It’s imperative to keep the tires and wheels clean: Salt, snow, ice and road debris that are not washed off the tires can lead to rubber deterioration. The metal on the wheels can corrode after exposure to chemicals and road salt.
Washing tires and wheels is not difficult. Simply use warm, soapy water and wash inside and outside. Avoid petroleum-based cleaning solvents, which can damage the rubber, and be cautious with high pressure as well.
