Do tires go bad?
Turning 25 in May so I took the big step and bought a 03 EB Z06 w/ 17k miles. All stock down to the original filter and tires. It is my dream car but I have one problem. Do tires get hard after time and go bad? I am asking because I lowered my tires to 28psi and still no way to grip (even at the end of third and shifting into fourth). It is rediculous, I had a Z-28 w/ spray before this and it gripped better. Just wondered it anyone heard of tires getting hard after time? My friend has a 02 Z06 and can launch at 2k, I can't even roll on the gas in first. Kinda sucks I want to fell the pull like my friends.

its the stock tires for the most part. Tires can go bad in the sense of how was the car stored if ever stored. A lot of eviromental factors come into play here. Some have had tires go bad after a few years way before tire tread would come into play. Does your friend have stock tires as well?

The F1 Supercar tires are best in tempertures between 70 - 85 degrees, (I think I got that temp range right).

And, I also agree with the cold temperature "problem post".
These factors would work together to MULTIPLY "the traction problem".

Can I expect that the Garage will keep these tires new for a year? (when I get the Z06)

They do!
Usually as a result of bad parenting. I went to school with this one tire, dropped out, went totally out of round.
I think he eventually went bald, and is spending his last years in a landfill somewhere.
Very sad...

Tread depth has nothing to do with performance tire life.
as ppl have mention exposure to UV light, weather, and one other thing is heat cycles. How much has that tire been up to competion temp?/
If you looking at milage, I have some tires in my basment with less the 500 miles, I can sell you cheap. Only problem is they have 12-14 heat cycles and they are shot.
For normal GY F1 or street tires on a corvette, IMHO tire life is 2 years max no matter who little the car has driven.

I always put them in black garbage bags in addition to "out of sunlight, in a cool, dry place".
I really don't know if this helps by keeping air from circulating over the tires,
but it can't hurt, and it made me feel better.

1. Stock Goodyears suck below 50-60 degrees.
2. All tires cycle out, and typically do so by the time they are down to 2-3/32nds of tread depth. (my personal experience at least)
I'm planning to buy a new set soon, probably Kumho MX's.

Put the tires in black plastic garbage bags and in the garage untill I mounted them on rims.
