Ya, my butt-o-meter is not that sensitive, though I can tell the difference between tire brands I've had on the Camaro. Thanks for the info and not taking offense to anything said.I knew the minute I got in the car last spring that something was off. That being said, my seat is extremely sensitive vs a normal driver. I’ll feel a difference from a minute change in pressure from tire to tire in my car. Ones a regular driver would never even sense. Most will not notice the differences that the compound change causes. To me, it’s very noticeable.
