Excessive Rear Tire Wear!

[dwest]

I've got 150,000+ miles on my '04 G35 coupe so I know all too well how it eats tires for breakfast. And I've tried them all....Michelin, Dunlop, Goodyear, Falken, Cooper, Nitto, Firestone and maybe others that I can no longer recall. But lately it is eating my rear tires like it's a free all you can eat buffet. I've gone through two sets of rear tires in about five months. I put four Nitto's on about five months ago and within 6,500 miles (about three months) the two rear tires were completely and dangerously bald (a rainy day in FL with bald tires is a bad combo). Blaming it on the fact that they were Nitto's I replaced the two rear tires with some Falken's and within 4,500 miles (2 months time) they are now also bald. And when I say bald I really do mean bald all the way across - there is no tread left (you see the whole penny!).

It's not the alignment because I had it aligned when I got the Nitto's put on. It's not the tire pressure nor the way I drive. And while I do commute 100 miles a day (hence the high mileage) it's 90% highway driving and I've been driving the same way to the same place since I got the car in 2003.

I took it to the dealer and they put it on the lift and they don't have any explanation (other then wanting to sell me two new tires).

Historically I could always get 25,000 to 30,000 miles out of the rear tires (the fronts would go farther) so I don't know what's going on. But unless Mr. Firestone or Mr. Goodyear decide to adopt me and give me free tires I can't afford to buy tires every 3,000-3,500 miles.

I'm really hoping somebody has an idea of what's causing this because otherwise I'll be forced to sell the car. Which I'd hate to do since I've meticulously cared for it over the years and it looks great.

Any solutions or ideas would be greatly appreciated - Thanks.

What is the tread rating on the tires?

I think it may be the brand and type of tires you are getting... have you been getting the same kind as you used to?

Try some tires that aren't so soft... I'd try the Toyo Proxes 4's. They are good performance tire but the treadwear is said to be almost double the Toyo TR1's

If your treadwear is even and you aren't burning tires there is no logical reason that you would be going through tires unless they were just soft.

You said you don't drive aggresively?

maybe its time to get a camber kit?
