Very happy with this tire. I don't know how, but it seems like I always have a flat tire on my car. So I did my research and picked this puncture proof tire based on reviews and price. I didn't really understand the technical terminology used in Revain's Q&A and reviews. So I just measured my 14 inch tire and the bar it rolls on and rode it. (No useful dates were stamped on the original bus, as people have pointed out). I chose this 13" tire because I couldn't find a 14" tire. Fortunately, the old tire was easy to remove and just as easy to "fit" the new one. Nice. It creaked a little, but not enough to complain. Didn't notice any difference in size. I only carry maybe 50 pounds at a time. The tire copes well with it. Only problem is it's so clean and shiny it makes my old car look dented! LAUGH OUT LOUD
