Instead of grinding the "keeper" off, you can install a valve extender which you can buy at most auto parts stores. Now it's easy to air up.
Hi, Ken!
So, after adding all this "stuff" to the wheel, (t-valve, valve extender, tpms) would it concern you at all the amount of balancing weight that would be required? That is assuming no other balancing option is used. Just wondering.
