I have use several types of tire plugs and this style has always been the best. They always have out performed any others on the market. When I saw these I had to order them for my maintenance pouch/bag I carry in my car so I'm ready if I get a flat on the road I just plug it without removing the wheel and use my compressor to reinflate and I'm rolling in no time. There's nothing like being prepared especially when it's so inexpensive to do. Even at my age of almost 60 yrs I can do it myself and save so much money because I don't have to remove the wheel a put on the spare, I don't have to call for a tow or wait who knows how long for the service truck to arrive. Lickety split I'm on my merry way.
