I just realized that one side of my gt3rs has uneven tire wear vs the other side. Passenger side is down to the 2/32” wear bars whereas the driver side is almost 4/32”. Whats interesting is this variance is even on all tires (i.e the insides and outsides of all 4 tires are evenly worn) and that the delta between passenger side and driver side tires are identical when you compare rears vs fronts. The car tracks straight and doesnt pull to one side and there is absolutely no abnormal behavior in the way it drives. What could cause this?

 

What direction are you running on the track. This has a huge influence on tire wear. Time to rotate your tires.

 

Not driving it on the track and I m not sure if this plays a role in street driving.

 

A subtle alignment issue can create this sort of left-right variance over thousands of street miles, but wouldn't be noticeable in terms of street performance, pull to one side, etc.

Get it properly aligned by a competent shop.
