Depends on how you drive.

Michelin says 10 years max. As long as they are inspected yearly.

I do spirited driving but typically stay under 90. Don’t do much in the way of racing. Still good tread even in the middle portion of the tire.

Hans,

Thanks. The tires look good.

No sudden moves or heavy power when cold. Take it easy.

Ask me how I know that already.

Yeah, that's true for most "summer" performance tires - Nittos for sure!

Time for new (for me) is triggered when traction when warm reminds me of traction as tho it was only 30º!!:eek::eek: My last set had over 50% of the tread left, but they were 5 years old and were definitely past their prime (for spirited driving...very spirited!).

I’ll be reviewing this issue w Dr. Greekenstein over lunch today.

By 7 years, the tread may have decades of life left, however the tires become noticeably hard and slick.
Cold weather makes an already hard and slick tire downright dangerous.
Being as I sincerely want to live longer, I have been changing mine out at 5 years.
Good Year GS D3 Eagles or Michelins seem to be most favored yet most expensive, although the expense should not be the deciding factor.
Have used Nitto 555's and liked them, not loved, but liked.
The Toyo Proxes Drag Radial looks promising although only for folks who avoid driving in the rain.
The GS D3 is the best tire I have had on the car, although those who have used them and Michelin swear by the Michelins over the Good Years.
My only reason for not selecting the Michelins were that you need one size up to 335, and the good years were actually available at the time I was replacing, which is somewhat rare.
A new cheap tire like Sumitomo is often better than an old expensive tire simply because the rubber hardens as it ages.
Keep us posted with your results and the "feel" of the new ones.

I won't keep anything over 5-6 years old on my cars. Beyond that, and the grip/traction just drops off way too quickly. By 9-10 years old, even if the tire looks great, it will have probably 25% of the grip of a tire that is less than 5 years old (have experienced this multiple times).

The Shelby wheels I bought had PS2s that were 9-10 years old, and they were night and day difference to the 3-4 year old Goodyears that were on the wheels I took off.
