so i have stock size Goodyear eagle rs-a tires on my g37 and the rears wore out after about 5000 miles. this is my second pair of those on the rear and second time wearing out this fast. i have no idea why this is happening. the wear is even too and i don't really drive that hard

 

Do you have a camber kit?

 

yep i have a camber kit

 

Alignment, aggressive driving, incorrect air pressure, lack of rotation, etc. Could be many factors. Typical to go through rears faster than fronts on a staggered car on coilovers.
