Anyone know what the treadlife for the 19"s? Been looking everywhere but couldn't find any warranty information on the treadlife, I'm guessing it's somewhere between 10-15k miles?

 

your guess is approximately right. If you take it easy on them, they may last you two seasons if you change out for winter.

 

I was checking the tires at the dealer. The treadlife rating was something like 160, somebody correct if I am wrong.

 

I don't know if they were rated that high, but I'e heard a large number as well, just can't recall. I am just going to visually inspect it and when its time, its time. All depends on how you drive (i.e. peelin out, taking sharp turns, suspension mods which aren't complete meaning negative camber, etc)

 

From what I understand a 100 treadlife is the benchmark. The old pilot sports were rated 220 meaning that they had twice the life of the benchmark.

 

It really depends how much toe-in your car came with too. Our cars need a lot of
toe-in to prevent bumpsteer especially if you've lowered it. If you can live with a
tad bit of bumpsteer, get the car aligned to gsedan35's recommendations...you
might not even feel the bumpsteer at your stock heights:

Front: total 1mm (approx 0.08 degrees total)
Rear: total 2mm (approx 0.20 degrees total)

 

Treadlife is 140

With no rotation, I'm hopeing for 10K.

 

Guys you can't compare treadwear across brands, say if the Pilot Sports had twice the treadwear rating of the Potenzas, it wouldn't mean that they'd wear twice as long. 00-03 Maximas came with 50-series Potenza RE92s which are also graded 140. Many people have gotten 35-40k miles out of them. I can't say that the stock 19" will be good for a whole lot more than 10k, but Bridgestone treadwear ratings are just a little on the low side.

 

I just looked at my car (05 w 19's) and the Bridgestone Potenza RE050A's have a treadwear of 140, Temp and Traction A

max

 

bmw z4 use this same tire, in fact i believe this tire made its first introduction to the market on that car. from searching z4 threads, they average about 18K miles.

 

Treadwear ratings are virtually meaningless in my experience. Ones with 400 wore like 200's, 160's wore like 300's etc. regardless of manufacturer. MikeinAustin has a good answer taht seems to be consitent to other threads I've seen for our cars.
