Tire size vs riders weight

[boywander]

Am I the only one on this forum who like skinny 23mm tires? Are there anyone who is currently using 23s and don’t plan to go bigger? I also am a tan side wall fan a well. Call me odd but I still using 21mm sew ups. I have ridden on gravel roads some off-road and don’t think much of it. I mean it makes sense if the rider weight is heavier then a bigger tire is better suited. I shake my head when I see a skinny person 120lbs riding 25s or even 28s pumped up to 100psi or more.

Anyway I’m just throwing up a discussion about what is the common sense on tire size vs riders’s weighs.

[Allcarbon]

Made the switch a couple of years ago from 23s and 100+ PSI, to 25s with 85 in the rear/80 front. I see no reason why I'd ever go back to 23s as a skinny person. Felt like I was riding on basketballs.

[mass_biker]

Caveat - all rim brakes here.

1) Ran 20c and then 23c for years and years. Albeit on narrower rims
2) Got a bike with more clearance
3) Began riding 28c tires on the road - felt way too slow and sluggish
4) Moved back to 25c tires on my HED (Belgium+) rims - felt very comfortable but still slow and sluggish
5) Now generally back on 23c tires on my wider rims and love it*

The only materially "wider" tires I'm running are Panaracer gravelking smooth 32c on my winter wheels (stock DT Swiss) - which have also been great in the rough stuff/gravel and also manage to fit on that bike (#2 above) with more clearance. Again, rim brakes for all.

FWIW - I am ~ 140lb or so - and running my 23c tires on the wider rims in the 75-80psi range. These feel great - snappy, light enough - and definitely more comfortable than when I used to ride the very same tire on the narrower rims.

* also running 26c Panaracer gravelking "smooth" on one wheel set - these have tan sidewalls to boot - and have been super...

[nobuseri]

I ride 23mm, mostly, on wide wheels. Tires fill out very nice; no issues here. Haven’t really ventured above 25mm on my road bikes.

[old_fat_and_slow]

I ride 23's on rear and 20's on front. Granted I ride on pretty good road surfaces. None of that chip seal crap. I am quite bummed that I can't find 700x 20's any more. I plan to ride 23's as long as I can find them. I don't even like the looks of 23's compared to 20's.

Man since when did everyone,s rumpouses get so sensitive? When I first started riding. Eveyone was riding 700 x 20's pumped up to 150psi. (gottah minimize road resistance yah know.) I backed off the pressure some, but 700 x 20's ride fine to me.

[Dave]

At 135-140, I'm using 25mm on 17mm internal width zondas. I use 80-85 front and 90 rear. Seems comfortable enough for me.

[vincenz]

Amen, brother. I run 23mm on all my bikes. I only use 25mm on carbon or alu bikes because they don’t have as refined a ride as metal frames to me. The ride quality gap is narrowed a bit more with the slight increase in width in those use cases. 28mm and up are dead in the water for road riding for me. They handle like lazy hogs and weigh like them too.

It is nearly impossible to find anything smaller than 23mm clinchers.

I remembered riding 18s and 19mm @120psi.. lol

[clyde the point]

240 and when Ritchey introduced the tom slick in '90 or so in 28 I made the switch then. 90 front 95 rear, though I used to do 100 each. Makes my wheels last longer and I've always ridden anywhere I can reasonably navigate.

[Peter P.]

I weight 130-135. When I rode 23's I would avoid pinch flats for a long time if I pumped my tires up to 100psi. I did it like this for decades.

When I started to experiment with lower tire pressures and reached a psi. where I could finally feel the tire providing some bump absorption, I started to get pinch flats.

I've now switched to 25's, remain at the lower tire pressure I found with the 23's, and pinch flatting is reduced.

So yeah; I could ride 23's if I pumped them up to 100psi. but I've discovered a slightly wider tire at lower pressure rides better for me while reducing the instance of pinch flats.

Shoot; I used to ride Michelin HD Comps which were 20mm wide and even at 100psi. pinch flatting was a regular occurrence. I quickly figured out these tires were too skinny. Maybe good for a TT, but not for road riding.

Interesting data point since I’m about the same weight and on 23s front 70-75 rear 75-80 narrow width rims 14-15mm inside.

[Ozz]

...When I first started riding. Everyone was riding 700 x 20's pumped up to 150psi. ...

+1

When I moved to 23's I thought they were plush! At 175+ (back then) I would still "snake bite" flat quite a bit on the 20's....not a problem at all with 23's.

All of a sudden, everyone is on 25+'s....what did I miss??

[pasadena]

I ride 23's, 24's and 25's
The 23's are fastest. 24's (Specialized SW Turbo - odd size) felt fast as well.

I put about 85psi in my tires, and just squeeze-check daily. I'm down to 50-55 sometimes before I put more air in them.

I do notice 25's are a decent compromise on rough roads.

yes, this describes me too. i dont fuss about with tire pressure too much. pump them up high and let the pressure drift.

really, there is so much variation in tire size, even for a given label, i can hardly tell a difference between my 23c tires and 25c sometimes, especially if you add rim width into the mix.

i would never run 28c on the road. they feel too heavy and sluggish to me.

125ish pounds here.

[ultraman6970]

I put the same air pretty much to every thing, close to 100 in the back and like 85/90 in the front, no matter wide or narrow.

Talking about narrow, have some NIB dugast silk road 20 mm tubbies moving around :D

Same with narrow NOS clincher rims aswell anodized and aero... cant remember the brand, think wolber. Which doubt will have any problem to fit all the way to 25s anyways.

Right now since im always in a budget to get tubulars if i can get 23s i go for those but lately 25 is like what is all over the place but always have a set of wheels glued with 27s in case there's a century, not because are arguably more comfortable but because are thicker and harder to puncture.

[Blue Jays]

My concern is ensuring sufficient air to protect expensive rims from unwanted impacts...due to deteriorating roadways.
One does seem to eventually find that "magic number" that gives best performance, fastest speed, and adequate freedom from pinch flats.
My roadbike riding is typically done on 23, 24, 25, and 27 mm tires. I think that I enjoy the 24 and 25 mm tires the most.

[pasadena]

exactly
plus 23's are still the most aero, no matter what width rim you use.

[boywander]

I found the popular conti 4000 sidewall casing is softer so I always pumped a little more pressure than Vic for the same size tire.

[Monsieur Toast]

I think I'm doing it wrong. 190# rider here, 58cm frames.

I started with 28s at 100psi (Conti GP4k) when I got into road cycling on my Della Santa.

But I much prefer my "new" Ottrott setup with 25s at 110psi (Conti GP5k).

[Bob Ross]

Am I the only one on this forum who like skinny 23mm tires?

No


Are there anyone who is currently using 23s and don’t plan to go bigger?

Well...I weigh somewhere around 172-175lbs.

I own four bikes:
- two of them are road bikes with 23mm tires pumped up to 100psi
- one of them is a road bike with 25mm tires pumped up to 90 psi
- one of them is a gravel bike with 32mm tires pumped up to 70 psi

I have no plans to go bigger on any of the road bikes.
Sometimes I screw around w/ 35mm or 37mm knobbies on the gravel bike.

Those tires were wicked to be kind. Rode amazing but I must have cut a dozen of them at the sidewall. Just a nick and they would slice. Fun :)

[johnniecakes]

I have 23's on 6 of my 8 bikes. Most of my wheels have 17 ID rims and I run 110 PSI. I weigh 165 lb. Tried 25's but didn't see the appeal so I stick with what I like

[jamesdak]

Well I'm that guy. I ride 700 x 25's on just about everything I have unless there's not clearance. Usually running 80 psi front and 90 psi rear. But I've pretty much been off the bikes for 7 months and gained around 30 lbs. So as I sort out the knees and try to get going I'm riding them at 90/100 F/R. Smooth pavement does not exist where I live and I find myself just as fast or faster on the 25's vs the 23's. The 25's also leave me feeling fresher at the end of my rides. A few years ago I rode a newly acquired old Lemond on the 19's that came on it for a couple of days. Lost three fillings out of my teeth, no really, I did. ;) Talk about getting beat up on the bike. Guess I'm the wuss around here, LOL!

Thanks for sharing. Sorry for your teeth on the 19s.

Width, weight and pressure. There's a relationship there, and a 120 lb person riding 28mm tires inflated to 100psi is running them way too hard. Even a 200 lb person usually doesn't need 100 psi in a 28mm tire.

[Kirk007]

all you thin guys on thin tires! I look down at a front 23mm wheel these days and think I'm the carnival clown riding the tiny bike.

My favorite road tire is Veloflex arenberg/roubaix which measure out between 24-26 depending on the rim I've got them mounted on. But I've found that 25 tubeless tires on wider diameter rims that end up actually being around 28mm are just fine for me too. And I have some Panaracer competition clinchers that are 28 and measure out close to 30, and they're fine too. Pressures range between 90 and 70.

Our roads are fairly crappy and I'm not doing testosterone induced group ride sprints so I'm not looking for ultimate speed, but I don't think the couple of mm difference in width is making me any slower. Of course my tires need to offset a bit more mass than many of you as I'm 6'3" and 210-212 in good months and up to 220-225 in the winter so there's that.

There's nothing more important than that when it comes to reasoned selection of tyres.

[Davist]

I weigh around 180-185 this year. I ran 28s forever, since early 90s, came from bmx/mtb and the 23s (or below) looked too skinny, but eventually in the Schwalbe Ultremo version were about 34 and felt "squishy" even at 90psi. Went back to 25s (had a bike that wouldn't fit 28s), then got a disc bike that fit 28s, had 4kS2s which were about 32, now I'm on 32 (true to size) 5kTLs at about 65 back and 60 front and loving it, faster than ever and plush. So I guess I'm the source of all your ire :), enjoy.

[5oakterrace]

I am 200-210 pounds and ride Cont. 4 seasons and 4000s, 23 x 700, at about 100 pressure. I think they are a "wide" 23 compared to others. Have to keep the pressure up to avoid pinch flats. Have not had a flat in eons but my roads are quite good. The 4 seasons are a rugged tire in my mind. Flats really ruin a ride. Once my supply is out I may try 25s but maybe not as my experience with what were much wider tires on a gravel bike left me with a sense they are heavy and slow. 23s are fine.

[soulspinner]

170 lbs, 25 mm on 17 inner width 85/90 ish. 23s on another bike width 18 inner width rim, 85/90.

I’m sure it’s not uncommon 5-10 years ago
90kg on 23mm @100psi but today’s norm is not the case.
About how wide are your rims?

[Seramount]

150 lbs, run 23f / 25r at 85 psi.

[ddtn]

I've been the same height/weight since junior high (5'11-6', 170-180ish lbs), was on 23s at 100psi for probably over 15 years. Worked for me in almost every scenario on the road.

Now in my mid 30's, my body weight is about the same but I can tolerate aches less. I find that 25s do the job most of the time at 80-90psi. I still pump them up to 100 to feel like I'm going fast.

Have a set of 28 Schwalbe Marathons on a single-speed converted English 3-speed (Stormy Archer hub) commuter bike. The bike on 23s was very bumpy, but on 28s at 80psi it's plush enough that I don't really see the need for anything wider. I feel like my body has been trained to take a harsh ride, so I don't require much in terms of comfort.

[David Kirk]

It's interesting....I rode an old bike last night with 23's on it. I've not ridden 23's for any real distance for 20 years and the difference in rolling resistance was noticeable. I weight 180# and had the tires inflated to 105 R and 100 F.

I typically ride 28 mm tires on wide HED rims and they are smoother and faster rolling. Is there a huge day-and-night difference? No. Is there a noticeable difference? Most certainly.

This thread makes me think I'm either too old or too weak to appreciate what I have. Riding a gran tourish modern carbon frame (f8) with carbon 25mm deep wheels, 28mm veloflex clinchers aired up with latex tubes to 60-65 lbs. They ride smooth and fast, seem as compliant if not more than the 24 turbo cottons that they replaced.

Should I even be on this wide (26.7 measured) 28mm tire in the first place?

I only weigh 130#, and I'm not a racer or anything I would call fast.

FWIW, bike weight is under 15lbs in this config

[ariw]

I have a new pair of tubular Schwalbe Ultremo HT Evo 22’s, make me an offer, I ain’t going to ride them

23's on everything. Conti GP 4000 / 5000

Same weight, same tire, same psi. I find they can get a little harsh over the chip seal garbage, but overall they are still my faves.

The both measure 27.1mm in width on 19mm (internal width) rims at 87 PSI front, 89 PSI rear. Those pressures are for smooth pavement. If the pavement is old or rough (think chip seal...), I lower the pressure about 4-5 PSI. I find both tires to be smooth, comfortable, and reliable rides. And I consider both to be 27mm tires despite their labels. IMO, it's not what's printed on the sidewalls, it's what the tire measures that matters.

Greg

[CSBArizona]

Just another data point- I range from 128-134lbs and have been riding 23mm tubulars (Veloflex and Vittoria) almost exclusively on the often rough roads we have in Tucson.

Quality latex tubed tubulars somehow seem more forgiving to me than clinchers for a given size. And now now that I only inflate my tubulars to around 95 PSI. (and not the 120psi I swore by twenty years ago), they almost always feel and handle great for me.

Only the most broken, potholed pavement makes me consider going a bit wider for those roads, but the 25s I’ve ridden seem slightly ponderous to me.
Is there a good tubular in a 24mm?

[Seramount]

Now in my mid 30's, my body weight is about the same but I can tolerate aches less.

man, do I have some bad news for you...

[pasadena]

You would be faster and have much better handling at 90psi

Same weight, same tire, same psi. I find they can get a little harsh over the chip seal garbage, but overall they are still my faves.

Go tubeless next time you build wheels, then you can run a more supple tubeless tire and never worry about snakebites, I’m 215lbs abs use GP 5000TL tires. I’m riding 28c now on HED Belgium Plus rims.

[adrien]

I think it would also help if folks shared rims and rim inner width.

As for me -- now mostly on Enve 4.5, inner width 19mm.

Used to have Conti 5000s in 28; ran them at 100 / 95.

Now running Pirelli P7s in 25, though they're on the big side and measure up to about 27. Running 100/95. Great feel.

Just switched back to GP4k 23's on a wide rim and they are fine. The same tire in 25 blew up to around a 28, so I'm assuming the 23 is close to a normal 25 without measuring it. Curious about the new GP5000, are they closer to real sizing compared to the 4000's... I'm also on good roads and run about 80f/90r psi.

[vespasianus]

I must be an idiot. Until just recently, I was a 200lbs guy on a steel bike with 23mm tires pumped up to 120 psi.

Per my previous post above, my measurements for GP4KS II (NOT the earlier versions of the GP4K) and GP5K on 19mm (internal width rims) at 87/89 PSI is as follows:

GP4KS II (23) => 27.1mm width, 23mm height
GP5K (25) => 27.1mm width, 24mm height

Both measurements account for a few days of tire stretch after installation.

What do you run now rim inner width, pressure, and your weight if you don’t mind sharing?

[zap]

Oh man....I still think of 25c as a suitable fat tire for dirt (sprinkled with some rocks) roads in fairly dry to dry condition.......for a tandem.

[Spinner]

I weigh 185 and ride 23s inflated to 8 bars on two of three road bikes. I don't find the ride uncomfortable and I do like how they cut across the asphalt.

I ride 28s on my Rambouillet and they are certainly plush, but then again so is the geometry.

BTW, can the Rambouillet be called a gravel bike?

[boywander]

BTW, can the Rambouillet be called a gravel bike?


Good question. How about a road bike on gravel or mtb trails be call a cx bike?

Honestly I can careless what people call it but if you’re able to, all the power to you [emoji23]

[Hilltopperny]

I am 212lbs and have 23s on my steel road bike and 25s with wide carbon rims set up
tubeless on my titanium road bike. The 23s feel lively and still comfortable for every ride I have done on that particular bike. The 25s are smooth, but do not have the lively feel of the 23s. The 25s are likely closer to 28mm on the 18.6 inner diameter and 26mm outer as opposed the 15mm inner diameter of the old school wheels on my steel bike.

I enjoy riding both bikes and the wider tires and rims add increased comfort for the long haul although at the expense of ride feel. They still ride wonderful and don’t feel sluggish, just not as lively as the 23mm on old style rims. If I still had as many back and body issues as I did a few years back I would likely prefer the wider tire wheel combo for the added comfort and dissipation of shock they provide though. As it stands right now I like both and it really depends on what I am in the mood to ride on any given day.

I'm about as light as I've ever been right now, but not necessarily super strong on the bike this season.. the whole lockdown + some injuries has kept me from riding as much.

I always was in the 170-185lbs range in my 20s & most of my 30s. My diet has gotten better and I figured out some food issues the last 5 years and I stay closer to 170-175 all the time now. (I'm 6'1")

I always rode 23c tires and based on the recommendations on tire pressure I was basically always near the max pressure and it seemed like the ride quality suffered. When I'd get real light when I was fit I could reduce the pressure down closer to 110psi and the tires rode a ton better. I mostly rode Michelin 23c tires which apparently usually measured on the larger side.

The roads here are as bad or worse than they ever were, and they were never that great. These days I have 26c on one bike and 32c on the other bike. The 26c bike is pretty much the fastest bike I've had, I don't feel any real need to try some 23c tires on it. I think I have a set of Mavic 23c tires in the garage that came free with a wheelset... didn't use them long.

Road quality is a huge variation.. I go to Florida, California, etc.. and the road quality makes my head explode... flat out amazing compared to New England where "pothole" means 50 yards of terrain that looks like a bomb went off and a drunk guy filled it back in with rubber filler and random chunks of asphalt.

We're always copying what the Euro riders seem to be doing and last summer when I went to France/Germany/Switzerland the road quality there was flat out amazing too. Smaller tires for the win there.

Pros weigh 140lb?, and ride 23mm tyres.

So Weight X .164 = tyre size.

I am 215, so I need a 35mm tyre.
That works out perfect, my new Kirk has 35mm tyres. :)

Now we need a localized normalized aggregate size modifier.

pros are ridding 25mm tires now and they probably measure more like 28mm on wide rims so you need to step to 38s :D

Pendula always swing.


On my "road bike" I have been on 38s for some time. For my next road bike, I really want something Italian sitting on 23s or 25s. Maybe 27mm Vittorias but not anything more than that.

To wit: I rode fat 2.5" and 2.4" WTB Vigilante/Trail Bosses on my MTB for the past few years. Ordered a custom frame with clearance for 2.5s out back this year, even. Wound up switching to a smaller, faster, as it were, 2.35" Vittoria Barzo/Mezcal combo. My next pair will be 2.25". Clearance for days for nothing. Go figure. But these tires are faster, alright!

Today I rode on victoria open tubulars 23mm
On maverick ksyrium elite pumped to 74 front and 77 rear. I’m currently under 140.
My observation is that it rolled very nice on smooth fine asphalt.
When the asphalt is aged or weathered a bit. I start to get feedback a little buzzing feel.
When I’m on long descent with similar or worse surfaces my hands and arms feels a tingling sensation. Any longer would probably feel numbness.
So I’m pretty sure I could have and should have let out 10psi on both tires to have changed the med harsh ride to a comfortable ride. But I was too lazy to want to stop for that. Figured it would build character to suffer through any minuscule things. [emoji38]
At the end I think 23 are way big enough for me and I wouldn’t gain much going bigger.
