There's a ratio of inside rim width to tire width that gives maximum tire volume. If the rim's too wide, the tire is overstretched. If the rim's too narrow, you get the "lightbulb profile."
Please correct me if I'm wrong. A 30mm tyre actually wides 33mm? I also want to buy a 32mm some model tyre but it must wide over 34mm etc? In this case, my frame and fork cannot hold it.
I have a pair of these 30mm Vittoria Corsa Pro on hookless rims that are 24mm wide internally and measured them 32mm. I had no luck (to say the least) trying to set them up tubeless though. First few days were fine, but then pressure loss was too quick. Sealant kept seeping through the sidewalls (the non reinforced area; Milkit and OrangeSeal sealant). Running the front tire with an inner tube now and changed the rear tire. The Corsa Pro shows wear on the cotton sidewalls and the tread (fine cracks). I’m not convinced of this tire although I was truly determined to like them.
Good example of rim being too wide for the tire; Look at that thread on top it is flat! So is the sidewall. The tire profile almost looks square. This tire profile will cost rolling resistance and handling smoothness.
Yeah, they look pretty square on the thread part. It should be a more round shape. I’ve ordered a pair of 30mm for Enve’s 4.5 with 25mm inner width, and I’m starting to think they will be too small.
@@outdoorbros_ no doubt they will roll but that profile is not optimal for rolling resistance or cornering. A lot of teams use Corsas in TdF, compare the profile and see the difference, no one has just side wall on the side, the thread’s shoulders should slope. On a side note, Pogi runs 28mms on C25 enve this year and his tire profile doesn’t look like this for whatever reason.
I get the same measurements with GP5K STR, 35.5 with the 32’s. I have two sets of these wheels for my gravel rig, so I was able to compare the different sizes and I was pushing 20 more watts with 32s mounted to maintain the same speed at around 20mph, so maybe an aero issue?
If you like the wide wheels, I also have the 52/63 on my Supersix with 30s, they are supremely quick and lateral stiff, and much less affected by windy conditions compared to my older Tokens Konax Pro or Duraace c50s. They also have a 25 internal width, but a little wider externally to maintain closer to the 105% rule.
I will never understand y people care what size the wheel comes in at. Almost Everyone is mesuring the extra width of the sidewalls instead if the actual tread that u ride on. And of course their number r different from rider to rider, most of us have different wheels and tires

I’m surprised that size fits an SL7! How much clearance do you have left with these tires?
Still a decent amount.

I have around 500 hard miles on them now and they’re great- no issues.
Totally fine on my Reserves. Had a friend use the same size on his 3.4’s and no issues.

good eye, good comment.
I’m using 28c Schwalbe Pro One, and it goes 31.5 for front and 31 for the rear
Good intel!
Could I ask what they plumped up to after a few ride please. If you still have them and remember that is
Awesome,extra width up front.💯👌🏻🚴♂️
Yup!
Ooof. I really hope they fit the supersix evo when I get it in a few weeks. I bought the tires already.
🤞🏻🤞🏻🤞🏻
@jonathan_guerrero did it fit the supersix Evo? Looking to pick up a set of 40 44 for mine as well
@@megaxzero88oh yeah for sure it did. I could have even gone 34s and I'm sure they would fit. 30s were perfect though
Tubes? Tubeless?
Tubeless, always.
I’m tired of these wider rims and tires. It just bring issues
Issues? I just moved to 32mm tires and love them.
Tubeless?
for me 28 already feels slagish... or maybe its just a perception
Could be! I've been primarily on 30's since and they feel great.
30mm nominal?
They do 20mm also
Too wide no? How is the performance?
First day on them and they felt fine today. Give me a few weeks and I’ll circle back.

Just ride on rims
