Conti grand prix 5000 30 /32 tubeless

[skiezo]

Looking at my first go at tubeless. My bike can fit up to 35's.
These will be mounted on 25mm external width rims.
How wide do the conti 30 and 32 blow up to?
I am looking to go no wider than 32/33mm actual width on these wide rims.
I found some post on other brands but not much on the conti's.
Thanks Brian

I don't think there's a 30.. I run 32 TLs on 25mm id rims and they're basically "true" with 32 width when 1st mounted, grow to 33 after a while. I use 55-60psi with great results at 185 lbs. They last about 4k miles in my experience, highly recommend.

Perfect. Thanks for that info. I am looking for a true 32 so these will be the ones.
Will be ording a set today.

Very similar to Davist, although I am running my GP5KTL32 on 22 ID rims. They measure a true 32, roll fast and last.

My 32s are mounted on Belgium black rims and are a great ride.

I have GP4Season 32s on another set of wheels (DT Swiss 411s) and they're not the same ride. Duh.
