For starters I know that tire wear varies wildly depending on driving style. I am just looking for a little insight. I drive what I would call spirited on the road, never tracked. I went through stock rears in 12,000 and switched all 4 at 25,000. These were of course OEM Potenza S-02's with treadwear of 140.

At 25,000 I switched to new 17" wheels and Goodyear F1 GS-D3's with a treadwear of 280. Rears are now in need of change, (inner part of tire is basically a slick).

How can a tire with a treadwear rating of 2x another, (140 vs. 280), wear at the exact same rate when driven virtually the exact same??

Also, is this what others have seen with the Eagles??

Thanks for any insight!

 

that is exactly why you cannot compare treadwear ratings between different manufacturers

 

What's you rear toe? Knock it down to 0.2 degrees total and enjoy better handling and much longer rear tire life.

F1 GS-D3's were discontinued a long time ago.

 

Flip the rear tires

Left tire to right and right to left

You now have good tread on the contact patch

 

It's possible (likely, even) that you began with less rear toe, and ended up with a ton more.
After an alignment a couple of years ago, my cars handling was getting weirder and weirder, and the wear rate went totally nuts (3000 miles on Dunlop SportMax TTs => BALD).
Apparently they hadn't tightened the adjusters enough, and the rear toe had gone from ~0.2 deg total to 1.05!
Got it realigned and had ostensibly shorter-lifespan Hankook RS3s installed. They now have close to 15,000 miles on them, still have ~1/4 - 1/3 tread depth remaining.

If you want less rear tire wear, minimize rear toe. As in, less than the minimum spec requirement. I recommend 0.2 degrees total.

 

Thanks a ton for the rear toe input. I will make sure I find out first what the toe is when they pull them and also make sure it is set to 0.2 on the new set.

Now I'll just have to figure out what tires are best to put on....

Thanks everyone!!

 

If you are looking for the longer wearing tires take a look at the ultra high performance all season tires. They are going to give good tread life and the longest mileage. If I can help with the tires let me know.
