Lee, sounds like a car that one of us should hang on to! You are probably also a careful driver who does not punish a car during takeoff or the brakes during stopping. Keep it up! BTW: How do you like that 3400? s
2001 Trans Am, driven extremely hard.
Stock Tires were Goodyear Eagle F1 GSes, they made 23,000 miles. (IIRC the rating was 300) Replacement Tires are Kumho Ecsta MXes, with a 220 rating, they've made it 12,000 miles and aren't totally bald yet.
FWIW, my BF Goodrich Drag radials have a treadwear rating of 0. :)
The Canadian Tire Predator GTS's on my wife's Beretta made it 45k miles before they started to self destruct, there was still plenty of tread left, but the sidewalls started to crack and there was internal belt separation. Unfortunately I don't know the treadwear #, but the treadwear warranty was 50k miles.

I don't. Why? There's more to a tire than just it's expected mileage per set. I care more about traction (dry and snow) than whether the tire makes it 50,000 miles or 500,000 miles. I've found tires have a useful lifespan of
I can see this giving really screwy numbers for snow tires that use a soft "outer" tread, and a harder inner tread.

True, I drive like an old man, because at over 50, I guess I am one. Also in an attempt to keep fuel costs down. But it has had several full throttle blasts throuhout it's life. The engine is great, except mine has the leaking intake gasket. It was replaced once under warranty, and it has been leaking again for the past 20,000 miles. Not a lot, but just enough to let me know it is leaking. I have used a total of 2 gallons of 50/50 Dexcool since the second leak began.

You appear to have a terrible misconception of the scientific method. People have given you good answers. I don't know why you choose to ignore them. Nothing other than BS has come up saying that 100 = 30k miles.
If you actually use the scientific method to find out how long a tire will last under certain conditions, you need to subject a tire to those conditions until it wears out. Then you get to repeat the experiment again and again. If the results are pretty consistent, then you *might* have the right answer.
Which of the newsgroups you cross posted to are you talking about?
Yes.

I'll bet if you drove all 150,000 miles in a conservative manner on the same test track you get close to the rated mileage. But the real world is not a test track. There used to be a study that compared tire wear state by state. My home state, NC, was rated near the bottom, mostly because so many secondary roads are recoated with a rock and tar mixture. This leaves a lot of sharp edges exposed that really wear out tires. My ex-wife used to shred tires at an incredible rate. She never, I repeat never, drove on a major highway. If she needed to get from point a to point b on the other side of town, she would wind through all the obscure highly cambered, twisty surface streets she could find. Tires that would last me 50,000 miles would not last her
20,000 miles. Your driving style also affects tire wear. Lots of quick starts, heavy breaking, and high speed cornering will wear out tires much more rapidly than conservative driving. My Sister had a 1980 Honda Accord. She actually had the car shipped to Europe when she worked their for 2 years. When she was back in the states the car was totaled in an accident. It had around 80,000 miles on the odometer. There were rust holes in the body, the car rattled and whistled like a banshee, the muffler had holes you could stick your hand through, but the tires were original and still had enough tread to pass inspection. My Sister just doesn't wear out tires. I think she is averaging over 60k on the cheapest tires she can buy for her current Honda Civic. The type of car also has an effect. I had a 1978 Ford Fiesta. It came with 12" Michelin tires. I read a recommendation that you should never rotate the tries for this car, rather just replace the front ones when they wore out. This is what I did for the first 8 years. Finally when the car had 130,000 miles on the original rear tires, I moved them to the front so I could wear them out before they dry rotted. The fronts were only good for about 40,000 miles per set (Michelins). I think if dry rot wasn't a problem, the rears would have out lasted the rest of the car.Ed
