Shimano wheelset will not take Michelin Pro Race tires(11 posts)

Shimano wheelset will not take Michelin Pro Race tiresRed Baron
Apr 22, 2002 8:25 AM
I have a set of R535 Shimano wheels and had fortezza's on them. I just got some Pro Race tires and could not get them on these wheels. Even the first bead was almost impossible to seat never mind the other side.

What's up with this? Anyone else having this problem?

Thanks.
Michelin's in general run small compared to other brandsPaul

that I've used. To get them on for the first time on my Mavic's, I have to use tire levers on the last section. They will stretch in time. Best thing is that they don't deflate as fast as the others.

Help me to understand this one.
They fit tighter, thus have less leakage. I've used many otherPaul

brands, and find that the Michelins hold air the best. I've also noticed that other brands go on easier. Thus, my conclusion. Others have told me the same thing. I have a set of Michelins on my Heliums, and ksyriums. I pump the Ksyriums once a week, and they are only down about 5 or so lbs. I rode over 8200 miles last year. The Ksyriums don't have the spoke holes drilled all the way into the rim, so it probably helps by slowing down the leakage from the tube. But there isn't much difference in the Heliums.

Again, just my conclusion over the years.

The loss of air from a bike tire is through the tube, period. The tire itself is virtually no barrier to air that leaks out of the tube, so a tire that is tougher to mount will have no effect on air loss. The reason the tire is harder to mount is the amount of rubber "below" the bead that hooks into the rim, not the diameter of the hook bead itself. If you have a leaking tube, and you submerge the tire under water, you'll see bubbles streaming out through the casing - it is not a gas barrier. Now you're suggesting that the fit of the bead into the rim is a gas barrier. Preposterous.
Same idea as tubeless car tiresPaul

didn't say they were air tight. If the leaking air has no place to go, or finds higher resistance ( like in electricity), or in tubeless tires, then the rate of flow will lessen due to resistance. In the Ksyriums with no spoke holes, you will get this effect.

Einstein has nothing on me.

A real pain the the butt to install, my finger swell up after changing the tires. It is not just you. What can you do? A couple of tire levers and a friend who has bigger arms might hlep.

It helps me out. I use them with my Rolf Vector Comps and the Axial Pros. I have more trouble when I use "regular" tire levers or none at all. I dropped my old speed lever on a century last year and went out the next day to buy a new one. Very helpful with the Axial Pros.

I run the Axial Selects (kevlar belted) as training tires. Pain in the a$$ to get on and off my Vector Pros. I used to pinch fingers and tubes all of the time, using regular tire levers. Much less now with the Speed Lever. Well worth the $7 price tag.

I always have to use tire levers on new Axial Pro's, they get easier with time. I'd rather have'em tight than loose.

I can get the Pro Racer better on the rim than the Pro's with my bare hands by the way, but i go back to the "normal" Pro's they are much stronger and stiffer ;) so
it gets even harder to put them on. I like the Pro's very much, when they are on the rim you don't have to worry about them anymore till you have a flat tire hahahaha
