Okay... this seems like a bald guy joke. Rubber minoxidil. There, I said it.
Jokes aside, this Goodyear technology extrudes new rubber compounds that harden in air, replenishing the tread as you drive. The idea is to make a tire that can last 100-300K - essentially for the life of the car. Goodyear folks claim they could even customize tread compounds for milage, performance, even a special type for electric cars.
The only question for this developing tech, could it keep up with tire shredders like rabtech ?
