Pedal bikes will get up to speeds well over 20mph(30kph) going downhill and their tires are still safe.
- gambiting 5y agoI mean......based on what? Like don't get me wrong, I used to do a lot of mountain cycling on a road bike, and going downhill I'd approach 60mph(100km/h) easily.....but I was never under any illusion that it's "safe" to do, or that the manufacturer even tested the tyres up to that speed. They just happened to work when we did it.
- rich_sasha 5y agoRoad bike tyres are clearly expected to hold at speeds like 50-60kph... that’s not even fast for a descent. And commuter bike tyres are usually substantially beefier.

- cranekam 5y agoWhat would you expect to happen to the tyres at high speed? I assume at some speed they’ll fall apart or something but that surely must be at more than 100kph. The things are already holding in air at 100psi+ — why would rolling quickly be an issue? Of course, at 100kph you might have other issues, like stopping in time, but I wouldn’t expect my tyres to fall apart under me. If you have any further information on this topic I’d love to see it!
- dharmab 5y agoLook up "tire speed rating" for answers to your questions.
- bigfudge 5y agoYou only have to look at pro racing to know it’s not common that tyres explode at high speed. Other bad things happen! But tyres only really go on descents when rim brakes melt carbon rims. That’s why many riders used alloy rims in mountains until relatively recently .. when high temp epoxies became more widely available.
