It is key on a mountain bike. On a road bike, it is important to keep your pressure up for less rolling resistance and not quite as important for traction.Quote:

I have run, even with regular tubed tires, as low as 25 when the conditions were just right. I was probably asking for a flat, but I took the risk. By the way, I did not flat!
