That depends on what you use as fluid and how much you get. I would call Rimguard and see who is their local vendor, the price varies greatly on rimguard so shop around. You can also use windshield wiper fluid, that is probably cheaper but it is not as dense. I am not sure if anyone still uses calcium-chloride anymore but that used to be popular but it will eat your rims eventually. I know on another forum some folks did it themselves. :bigbeer:All of this is good info. thanks yall. and to change the subject a little, what will it cost to fill my tires with fluid? i am taking it to the dealership tomorrow to have the hydraulic remotes installed. can't wait to get my tnt.
