wow... this is really cheap price. since 2 years i plug in my car, 4000K is the best for road or hill drive. still now no problem at all. Durable & Reability, so at here i give u a BIG BUMP, THANKS a lots. GOOD DEAL.
I know this question is best answered by a mechanic, but I need to know in advance whether if a damaged air valve itself can be replace by its own or must the entire tyre or entire tube be changed?
