Tire size vs riders weight

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?

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

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.

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

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

Pumped up to 120 psi

I'm 145 pounds.

Clean roads around here, and I like to feel the paint stripes

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.

At 180 lbs (including all kit, helmet, water bottles, computer, seat bag, etc...), I ride Continental GP4000S IIs in 23mm width and GP5000s in 25mm width. 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.

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?

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

[pasadena]

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

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.

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.
