Tire life expectancy

I have 55,000 miles on my Cooper tires that have a rating of 780. Should I expect around 78,000 on these tires or do the ratings mean something else?

The Treadwear rating is only comparative - it doesn't correspond to any specific mileage. So, it is only for looking at different tires to get a vague idea of how much longer one tire will last compared to another.I can't believe you have 55k miles on the OEM tires. Did you buy the car used with these tires or did you buy the tires at some point and put 55k on them?If the latter, you might be able to google and find out how many 32nds of treat they came with new, and take a measurement now to see how fast they are wearing. Then you can extrapolate the expected time frame that they'll be down to 2-3 32nds, as that should be about the absolute outside of safe use.My last couple tires never even made it that far - I'd think I could run them one more summer but then they'd get a flat and it was too thin to repair or I'd find out that the cords on the edge were starting to show and so it was time for a new matched set all around.

These tires are my third set since purchase in 2003. Original tires lasted 30,000, second set over 70,000(great set of Goodyears) and these have 55,000. IMO Goodyears are worth the extra price if you are keeping the car for a long time.I did the Geo. Washington quarter test on all four tires and all seem to lack enough tread for winter driving in Western PA. Tire shopping is a must now!

GOODYEAR! My experience with them has been very very bad. Your tire milage will depend on driving habits, inflation PSI, shock/strut condition, road conditions and other suspension/steering parts condition (I may be leaving some items out ). If you had goodluck with the Goodyear why did you switch? I've heard good things about Cooper but never had a set.My First set of tires on the TRIX lasted about 55K but some aZZhole lube monkey over inflated them to about 45PSI causing them to ride like rocks and ruined the tires (they cupped) and could have gotten another 10K out of them. I have the Riken Raptor HR tires and have been very happy. I know what you mean about winters in Western PA.

I was told this year by a "tire expert" at Costco that the tread wear number only means something within tires from the same manufacturer. In other words, comparing tread wear numbers between brands means nothing.I find this concept a bit strange - but not completely unbelievable. My factory Goodyear RSA's only have a number around 260 IIRC, but still have 6/32" of tread left after about 62k km of use. At that rate they should be good for close to 100k before approaching the wear bars, or maybe more. Goodyear doesn't seem to post a mileage wear rating for these tires that I've found.On our Mazda 5, we have Michelin Primacy MXV4's with a tread wear number of 620 - rated for 100k kms (60k miles). Maybe in a few years I'll know how they compare with similar driving - but I really doubt that they'd be good for over 200k based strictly on the tread wear numbers. With the amount of driving that car gets, they'll likely die of age first anyway:(

I got around 50,000 miles out of my stock tires from factory. Put on Goodyear Eagle GT's and they are about ready to be replaced before too long at 83,000 now.

FWIW - DOT has commented that tires only have a "shelf-life" of five (5) years before their rubber content begins to oxidize and deteriorate, which is *why* all new tires have a manufacture "date code" (week-year) stamped into their sidewalls.

The eagles aren't known for good tread wear but more for performance. I had a set on a Lexus SC300 that were done at 25K miles. Ofcourse it was a sports car and I drove it like one.

Based on Tirerack customer review the Eagle F1 AS is pretty decent for a hi po tire.

Quote, originally posted by Old Tele man Â»FWIW - DOT has commented that tires only have a "shelf-life" of five (5) years before their rubber content begins to oxidize and deteriorateI can certainly relate to that . Had an original set on my 1992 F-150 (bought new and still own) have a "blowout" after only 42K miles on the truck ... BUT they were 16 years old . Can you say DRYROT Had to replace them all due to "old age". The new set have four years on them and only 5000 miles on them to date.On my last two GMC 2500 servive vans, which are my daily drivers as part of my job, they both had Michelin LTX M/S tires from the factory and when I had to turn in the vans due to lease requirements (5yr or 100K whichever comes first), BOTH of them had over 90K miles on the original tires with no abnormal wear at all. They were just below the legal tread wear but were still rolling along just fine. VERY impressed with this truck tire! On a humor side, as long as you don't hit any objects in the road like I did, you should get 40-50k out of the Goodyear RSA's with normal non-aggressive driving

Nowonder why after we have our tire change over , the tires sound so noisy..According to Rubber Association of Canada , tire storage tips..StorageWhen not in use, tires should be stored upright in an indoor location, out of direct sunlight or exposure to strong artificial light, heat, ozone (electrical motors) and hydrocarbons. If tires are stored on their rims, the pressure should be reduced to approximately 15 psi to avoid cracking or deformation.

Because my summer tires are designed to give really good traction in the dry/wet by providing lots of rubber contact with the road over large tread blocks whereas my winter tires are designed to give really good traction in the snow/ice by providing very small tread blocks with many open spaces and a very flexible rubber compound. Not to mention the 80-100 studs in each tire...

Hey so do you use your factory steelie as your winter rims?
