The Goodyears have a treadwear life rating of 280, which is almost 30% higher than the Bridgestone and the Michelin at 220. They should last to 30,000, in my estimate. I got 20 - 25,000 miles on the Dunlop 2000Es on the E39 540. They're Ultra Hig Perf and listed with treadwear rating of 200, so you'd expect less life.

 

Wow thanks for the responce. I have had S02's on my 911 cab. loved them, but I'm concerned with the weight of the 545 being a little too much for the tire. I put alot of freeway miles on the car and tramlining really bothers me. Guess it's the Eagles for me.
Thanks

Thanks for the info.

2 weeks ago I swapped them out for Michelin Pilot sport ps 2 ultra hi performance

tires ......noise levels are much lower and handling is dope![per my teenage

son]. Recommended w/o reservation.

 

actually, the treadware rating you are referring to is not 100% in yoru context. The rating only applies to other tires within that Manufacturer's line-up.. In other words, you can't really compare a Goodyear 280 to a Bridgestone 200...

sorry for the correction!

 

Sounds like around 35,000 miles according to these owners:

"Totally impressed how this tire manages the torque of the E-55 with such quiet, smooth, and responsive operation. Tread life is exceptional as well. After 23k miles, the fronts still look great and the rears still have half of their tread. "

After 32000 miles and three snowstorms, I still love these tires. They handle great. Wet roads are no problems, and they simply dont hydroplane in standing water at highway speed. My rears are approaching the wear bars, but I did spin them a bit in snow and ice over the winter, but the fronts are still in good shape. About the quietest tire Ive ever used. They did ok in the snow, as long as I kept moving and no great inclines were encountered. I did get stuck going up out of my driveway a few times, a one foot rise over fifty feet, all ice. I will buy them again, but I am strongly considering winter tires, finally. -- Review Submitted 2004-09-06

 

OK, didn't know that. I thought the rating was vs. a general standard.

I went to tirerack and it confirms your point.

"The Department of Transportation requires each manufacturer to grade its tires under the Uniform Tire Quality Grade (UTQG) labeling system and establish ratings for treadwear, traction, and temperature resistance. These tests are conducted independently by each manufacturer following government guidelines to assign values that represent a comparison between the tested tire and a control tire. While traction and temperature resistance ratings are specific performance levels, the treadwear ratings are assigned by the manufacturers following field testing and are most accurate when comparing tires of the same brand.

Treadwear

Treadwear receives a comparative rating based on wear rate of the the tire in field testing following a government specified course. For example, a tire grade of 150 wears 1.5 times as long as a tire graded 100. Actual performance of the tire can vary significantly depending on conditions, driving habits, care, road characteristics, and climate."

So, that's interesting. You can't accurately use the ratings to compare manufacturers. So, what's the control tire, and what's to keep a manufacturer from choosing a really crappy one as the benchmark? Is that the point? That you can't trust the treadwear ratings? If so, that stinks.

 

I had the Goodyear Eagle F1 once and liked them very much!
