In my 2014 Limited AWD, I changed all 4 out after picking up a screw on the corner of the sidewall and was not repairable. 42,000 miles on the factory 20" Pirelli Scorpions. I replaced them with another set of Pirelli Scorpions. If it wasn't for that damn screw, I wouldn't have changed them. They were wearing beautifully. Nice even wear across the tread 5/32 Rear 6/32 Front after last tire rotation.
