Not quite tires/tyres but rims.
moved discussion from:
...so not to drag the great Envied thread off-topic.
I love the thicker spokes but can't get pictures out of my head of carbon wheels tearing the centres out. I think our local roads have way too many random pot-holes to be confident enough to run carbon but on the track you should only see performance gains.
I put over 30,000km's on my BST wheels, with probably 400+ passes in the 1/4 mile with my zx10r. I live in Canada where winter ruins the roads and never had a single issue with them.
The bikes destroying them at the track are 500-600+whp, and even that is a rarity. I have seen magnesium wheels get damaged very easily, and they are standard on a few bikes.
Truely awesome you have not had a problem and I sincerely hope you never do but it's certainly not only 500hp monsters that have had problems, the Internet is littered with stories about sub 200hp track bikes doing this on good race surfaces.
...and magnesium isn't much of a comparison. They have stopped using mag rims in World Superbike (WSBK) and in many other competitions too. In our local LSR rules they "don't recommend" (whatever that really means).
"Magnesium wheels are not recommended and, if used, shall have an initial Zyglo certificate and stamp available. Zyglo inspections made with tires mounted are accepted. Wheels are to be re-inspected if any adverse condition arises." -- 2017 Rule Book Dry Lakes Racers Australia
Brembo make some of the best magnesium rims in the world under the Marchesini brand, you need deep pockets and I'm pretty sure the MotoGP guys just toss them away nearly as often as they change tyres.
I'm pretty sure that both MotoGP and WSBK both stopped the use of carbon rims a few years ago, not to say they won't come back at some point.
Carbon wheels look amazing and I understand the performance advantage of something the will turn-in faster with less gyro and accelerate faster with less rotational mass... but as mentioned, the exploded pictures that everyone likes to share when there is a failure give me a twitch.
Some of these pictures are getting quite old and I'm sure the companies and their technology is in constant development too as they don't want any failures, ever. I get that.
I live near Carbon Revolution
and have watched their progress over the last 10 years. They have come a long way in that time and produce some of the world's best wheels now. It's their wheels you can get optioned on a Shelby Mustang (at a price!).
They are even using ceramic coating (think space shuttle tiles) on the insides of the rims to protect from brake heat and their rims are forged under very high pressures, not laid out in molds.
I wonder if any of the bike rim manufacturers are going to anything like this level of research, development and production values?
...or are they just knocking out carbon rims and letting the owners test them?
