My tires are well, lets say well used, but arent bald and are in decent shape. The right front tire came off the rim about 5 months ago, I brought it to a tire place they put it back on the rim. No problems. In the middle of a job a few weeks ago, same thing happened tire came off the rim. I get pissed take it back to the shop, for the hell of it I took my 10lb portable air tank and put some air in the other tires, then I put some air in the tire that came off the rim. To my surprise it fully inflated and seated itself perfectly back on the rim. Has anyone had problems like these with tires comming off the rim? I assume that the tire went back on the rim with only using the air tank is because its such a low pressure tire.
