not true. to much psi over manufaqctur rating will increase tread wear in the middle. to less and you increase wear on the outsides of the tire. both inside and outside.

even with camber issues you still create tire wear anyway you look at it. it is kind of like saying.....make the car toed in ( / \ ) to even the wear for your negative camber. sure...in theory your tires would wear evenly but why sacrifice handling for even wear? cant have best of both worlds....either handling...or tire wear...pick one
