Does more PSI in a Tire mean Quicker movement?
I have a Trek 7.3 FX and a few weeks ago I took a spill and the bike shop had to replace my rear tire. Instead of placing the same Bontrager Race Lite Hardcase (110 psi) where my front tire is, they placed a Continental Contact (85 psi) on the rear tire. Is there a difference in speed when there are 2 different tires with 2 different PSI's? This would not really bother me that much, but from time to time, I compete in 5/10K road races, so I was just wondering if it changes my speed with my bike or if it doesn't really matter that much. Thanks!
