My 02 Z28 still has it's original factory Z-rated GSC tires on it. I was looking at the DOT date codes and have two from 2000 and two from 2001. The tires seem to be in good shape and only have 12,000 miles on them. I'm not sure if I should trust them at 100mph+ being they are 8 yrs old. Should I be concerned about running them?

Are they dry rotted at all? Tire mfg say to replace them every 3-4 years, but if they aren't dry rotted I wouldn't worry about it.

I'm in the same situation with 11,000 on my '01 T/A. I called Goodyear on two separate occasions and they recommended changing the tires at the 6 year mark, but also hinted that if the tires show no dry rot (small cracks) and have been garage kept, then you can add a few years on to that. 10 years would be the absolute MAX unless just driving to local car shows or errands. I'm keeping mine for now since they are basically perfect and meet the above criteria, but will get some GSD3's within a year most likely. They are better than the GSC's and also are not prone to 'flat spots' after sitting. I might just keep the GSC's in storage for originality purposes for the future. They still have over 50% tread.

I would run them personally if they had no dry rot and they hold air perfectly

I have the original goodyears on my 98SS and they're like new. Granted I have low miles and garage kept, so no need to replace them.

I bought GTA wheels a few years back that had the original razorback tires on them with LOTS of tread. I drove on those until I had the money for new tires but even after we dismounted them they looked fine. I ended up selling them to a local guy for a few extra dollars

The problem with old tires is that even with a lot of tread left, the tires are not of the same elasticity as when new.

It's okay for a short time, but I'd replace tires, especially if the car spends a lot of time outside because it's the uv light that breaks down rubber. If it's a garage queen, then it's not as bad.

The car has spent 100% of it's life in a garage and there only seems to be a very slight amount of dry rot. I guess I'll probably run them a little longer, I'm also having a hard time finding performance tires in 16" rim size, so I guess that helps me make the decision to stick with em for a bit

I am still running on OEM goodyears on my 99 ws6. Still have 80% tread and the tires are in awesome shape. Mind you, the car is sheltered most of its life and it only has 35,000 miles on it so the tires have had an easy life so far.

keep some tire glaze on them and take it out of the garage every couple days and drive it around or just pull it out and back in so the tires dont flat spot and always have teh floor pressure on the same part of rubber

Usually people have the opposite problem The tread wears out before the life of the tire is expired! Haha.

I suggest only DD'ing these tires if you see cracks and wear after 8 years and 15k miles. If you plan on doing some heavy 100mph+ stuff you will want to upgrade for safety considerations.

This also gives you the option of buying aftermarket wheels with your new tires. This way you can always have your stock wheels + tires!

tire maufacturers reccomend replacing tires after 5-7 years,so I would not feel safe driving on 8-10 year old tires at high speeds. Just because they look "ok" from the outside, the structurally integrity of the rubber and other components is diminished over time. just my opinion though
