I have some 35″ BFGoodrich Mud terrain tires. I am starting to see some unusual cracks between the treads. I am guessing this is due to the dirt/tire shine combination that is on the sidewall and between each tread that I cannot clean off (scrubbed with a brush with soapy water). I am looking for the best way to remove this and the best treatment to prolong the life of the tire. Scrubbing 4 35″ mud tires for hours or days will hopefully be the last option.
