There is a rubber lubricant that will keep them looking good. In the spec sheet it says that it will renew them. It also works on rubber mounting to eliminate squeaks. I used it many years ago in the gas station to dismount and mount tires. We also used it on the local police cars when they were service and it made the tires look almost new. Beats tire black. Napa sells it and here's the spec sheet.

I don't own a vehicle that isn't old enough to drink.
