How are the rubber tires guys cleaning their tires? We use sxt for traction compound and I have used that and motor spray to clean my tires. Traction compound seems to sink into the tires though, and I am not sure if it has a negative effect on the next run. Motor spray usually leaves some gunk behind on the tires still. Also, are people really truing the rubber tires? Currently I just rotate them from left to right to get even wear and set my front camber to wear them flat.
