My wife has some old racing slicks she wants to get rid of since we're trying to clear out the house on her parents' property in Watsonville. The tires are at least ten years old and have been stored inside and wrapped in plastic, but they've never been used. So my question is: do tires go bad after a certain amount of time? Should we try and sell them, or just toss them in the recycling?
5 years is the shelf life on street tires if they are stored correctly. Race Rubber is even less.
I've used tires of both types that were far past their expiration date, but performance definitely suffers. Michelin Race Rubber like the Power Race series for some odd reason seems to hold up way better than the other brands when it comes to age, but it is still rolling the dice when compared to brand new race tires.
One of the problems with cycle tires is the hot/cold cycles. They need to be heated up to be effective and all those hot/cold cycles really add up. Noobs don't understand that, they just look at the tread and the costs.
