And you would be wrong. Age does deteriorate tires. The rubber compounds outgas from the moment they are released from the mold. You can vacuum pack a fresh tire, stuff it in a barrel, stuff the barrel in a climate controlled room, turn out the lights and lock the door and after 10 years the tire is still junk. The tread will harden, the sidewalls will stiffen, and the tire will lose grip and stability. All those sprays do NOTHING to preserve a tire because they can't stop the chemistry. If they did, you would have to coat the whole tire inside and out, not just the part you can see. If you just want something to hold the car up and look pretty, go ahead and spray up your old tires. If you want to experience the car as the designers intended, you need new tires. -- Mike > From what I understand, driving on NCTs is still fine as long as they have been > out of sunlight and have been siliconed over the years.
