Ok folks, here is the deal. I just had a bad time with the BT-021. I used to run 40psi, on both sets of Bridgestones that have been on my bike. I have read post that say psi is best at 42, others say 38, or even lower. I now have a set of Avon Storms and want the best mileage I can get out of these tires because I want to try them out. I run 2 up most of the time(95%), what say you? The bike shop said run no more than 38 for optimal performance. Please advise.
