I have a 2003 G35 sedan it runs up and down mostly interstate. I have a set of Kumo Escta Platinum the tires made it 73987 miles on the tires when one wore through on the inner 1 inch of the tire while the rest of the tread has a flat even wear pattern to it. The rear end of the car seems to be the issue causing the odd tire wear. The car drives great handles well its not driven hard, fast but not hard. The car makes a lot of runs state to state so it sees a lot of interstate time and 75-80 mph. If the tires did not last so long I could see a major alignment issue. Hard to argue over 70k the tire still has 5/32 of rubber on the rest of the tire. The car varies from carrying 2 to 4 people. I know camber can cause a similar issue but it normally would show across the full width of the tire not such a defined edge. Any suggestions?
Both rear tires are wearing like this.
