I have 235/40-18 P-Zero Rossos, about 14K miles on them. Just discovered the R rear tread is at the wear bar! All the other 3 have a bunch of rubber left, so it's not over inflation. I've been checking pressure about every other tank of gas; running 38 PSI in the rear, 41 PSI in the fronts. Any ideas? Bad tire??

makes no sense that the REAR one is out of tread.

my R-Fronts wear out faster than the rest because mountianous curves easier to take at speeed when it's a right turn (less threat of oncoming traffic)

too much toe in on that side. I'm guessing you lowered the car? if so, get an alignment

P-Fit

yep; can almost GUARANTEE that its an alignment prob.

If it where toe or camber misalignment, one side of the tire would be more worn than the other.

Strange thing was that only the inside edge of a 7K front tire got worn - severely (cords showing). Ultimately it was the dealer's fault for not doing an alignment after disconnecting suspension components during an engine repair; and they paid for a new tire.

Seems to be worn in the middle, just like overinflation (but that's not it)

Nope, no suspension mods; just changed to 18" wheels (Ronal LZs)

Need to rotate tires soon.
