I'm running Q2s and luv them...one suggestion is that if you are riding highway (straight) or commute but lots of straight road...I notice the center will flatten out quick if you just going stiff straight, I try to make full use of open lanes, tire rubbing...like if you were trying to warm up the tires....

One time I ridden bike 250miles highway...didn't think much able tire...just going straight stiff...got home notice tire somewhat flatten out (not much) on the center....

So I wanted to maintain the roundness of tire, I restrain myself from going straight, even if highway is straight....make use of lane width...this is only IMO

It may or may not mean anything...

Enjoy your Q2s...
