I had my General G-MAX AS-03 done at Discount Tire complete replacement, tires, Balance, tax, etc. plus the " REBUILD KITS" for the TMPS sys for each tire. This is gaskets(O rings) and new schrader valves for each tire. Cost tax and all out the door for $998.00, as I remember. Tire pressure max is 31 PSI on the Generals, not the tire rating on the car door. Hardly any miles yet, but run smooth and quite. No complaints!
