>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. The only two things that detiorate rubber tires are UV Light and Ozone, NOT Age. Applying silicone/eagle 1 tire shine/whatever should prevent the Ozone from destroying the rubber (dryrot). Look around the outside of the tire for cracks, and you know the tires have not been cared for. New tires are still the best option, but some NCTs are still very useable. Patrick 1880 "88NGONE"
