Quoted from currieddog:You also want to try to figure out what is going on that that is happening. Shouldn't be happening at that rate. Confirm correct coil and kicking action, etc.
The source of the supplier is also a big factor. I once purchased a set years ago from those "Guys" in Michigan, the rubbers did not last 3 months. I have had great long lasting success with rubbers from PBR & Marco.
