Is anyone else experiencing rear tires wearing out about twice as fast as the front ones? I've got a set of Bridgestone RE760 Sport tires on coupe sport wheels with 245/40R19 in front and 275/35R19 in the back, and rear tires are down to wear bar, measuring 2/32 thread depth, and front tires are measuring 5/32 thread depth, not anywhere near to being worn out. It's a staggered setup, so obviously I can't rotate the tires between front and rear. I've checked alignment, and it's well within factory spec. The tires are most worn in the center that indicates overinflation, but the rest of the tread isn't too far behind. This doesn't seem like a normal thing to me. I've had plenty of rear wheel drive cars before this, wouldn't usually rotate the wheels, and never had the rear tires evaporate so quickly.

 

Pretty common, it’s the same on mine but I have a square set up so I rotate them and it lasts much longer.

 

How many miles on the 'Stones, they are a quick wearing tire compared to most other Summer sets. It seems a bit excessive wearing twice as fast but it's surely possible w/ these cars depending how you drive.

 

It's not uncommon to hear people complain of faster rear wear. My fronts tend to wear faster but then I track me G several times a year.

 

I've got roughly 18k miles on the tires so far, most of the driving is sitting in traffic up and down the lovely 405 here in L.A., sometimes I will take up a twisty road, but that doesn't happen often. I can probably count on one hand how many times I've done a stand-still launch, never did a burnout or anything else like that. I autoX the car as well, but for that occasion I've got a separate set of wheels with Bridgestone RE71Rs on them. If the rear tires were wearing at the same rate as the front ones, I think I'd get probably 30k miles out of them, 18k seems a bit short for a 340 tread wear tire.

One thing that I decided to look into recently is the alignment. While the alignment was pretty much perfect to factory settings, I noticed that rear tires had like .17 degree of toe in, to aid high speed stability, and reduce oversteer. I've set it to 0 degree toe, and maybe that will help with the tire wear. I know excessive toe settings can definitely wear the tires out prematurely, since they are essentially scrubbing the entire time, but what tests that theory is that front had an equal amount of toe in, and yet the tires have significantly less tread wear on them.
