What size wheels and tires are you running in the rear and what pressure do you keep them at?
I am running a set of staggered Style 65s with 245/40 Michelin PA4 tires front and rear. After the first winter season running these I noticed that the rear tires wore the centers down more than the outer edges, almost like they were overinflated. I had been keeping the rears at 38 psi. The fronts are wearing perfectly. I ended up having to replace the rears early because the tread was getting too low in the middle and making them ineffective in snow/ice.
Last winter I kept them at 35 psi but still wondering if I need to reduce this even further. My summer tires are wearing perfectly (Michelin PS4S, stock sizes, 35 psi front 38 rear). I don't understand why only the rear winters are doing this. Even with a slight stretch (245 tire on a 9.5" width wheel) I would think that if anything, the outer edges would be more likely to wear down first. All the suspension components are relatively new and the alignment seems perfectly fine. And because I know someone will bring it up, I try not to be too rough on them with full throttle in lower gears and hard cornering.
Any help is appreciated.
