Do original oem tires become unsafe after a number of years?

If your GT has its original tires, do they become unsafe after being on the car for 7+ years? Should they be replaced regardless of tread wear after a few years?

YES, if you drive more than EP.

All it takes is a tire separation at any speed and you have major damage to your GT. I changed mine out a couple of months ago, just to be safe.

If you are considering a change, go with the BRIDGESTONES. Do not waste your money on another set of goodyears

Tires are nothing to ignor and almost every GT I see for sale has the OEs. First thing I do is get them off. (take it from an old tire lawyer)

I second the BRIDGESTONES recomendation. Much improved. And yes, tires do 'age out' Even Goodyear recommends replacement of tires over 7 years old as do most other manufactures. Rates of failure are much higher as the tires get older and the rubber is much harder as well.

That is exactly what I did. Never saw the car with anything but bridgestones. Nice sticky tires right from the garage.

Goodyear F1 flat out suck. Get Bridgestones and never look back.

Personally, I like the Goodyears as a great rain, and even snow, tire. I've been caught having to go over some 8,900' passes in a freak snowstorm with half worn Goodyears (>1" of snow covering the road), and they stayed the course for me. And, in major rainstorms travelling across the country, they've been a great rain tire, especially when the car starts hydroplaning a bit. As a general daily tire,, I'll take the Goodyears. For the track, they are slippery and don't have the grip of other tires available. Thus, on the track, I have been running Michelin Pilot Sport Cups, which can still be driven on the highways.

+1. I'd keep buying them, but the cost of the rears is outrageous. $1,200+ a pair for 4k-5k miles? Yikes.

Tire Rack has a good article on aging. A couple of relevant quotes:

"The NHTSA tire aging field study also indicated a strong correlation of the speed rating with tire durability, with higher speed-rated tires losing the least capability with increasing calendar age."

"Our experience has been that when properly stored and cared for, most street tires have a useful life in service of between six to ten years."


The full article: http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=183

Remember, Mark McGowan drove the Goodyears at 200+ mph for hours. (It would be interesting to know what they looked like after testing).

Having said I am a proponent of new , not aged tires I have to admit I have one car with 21 year old Michelins.

As many already know, several years ago I bought the second production Viper made (VIN 00002) from Chrylser President Bob Lutz. I have kept the tires, which were mounted at the factory in late 1991 on the car for posterity. I take it around the block once a month and for that purpose they are fine.

By contrast, I am getting ready to change out the rear B--stones on my GT after 8000 miles even though they look pretty good.
