I've always said a repair is just that "a repair". But I am on my 3rd flat rear tire in about 2 years, each with about 2000 miles, one with a big nail, one with a large screw, the last one I don't know yet and at $200+ for a tire, well you know where this is going. I usually ride pretty fast, 2 up, and drag my trailer. With hot summer days heating up the tire, also it is a steel belt tire, what are your feelings on patching/plugging a tire for long term service?
