ive just recieved NOS BMX knobby tires, with the releasing agent still on them. its this thick white film all over and inbetween the tread. the guy that had them posted it as "still has the releasing agent on them, will need to be washed off before mounting. well im asking you guys, how do you wash it off? i cant contact the seller to ask, or else id just ask him. has anyone ever gotten tires like this?
