My truck’s spare tire hasn’t been properly inflated since 2002. Ok, I know that’s a bad sign, but it is indeed a fact. I should point out I’ve never had a flat tire in the entire 40+ year history of this truck, at least never when using it, so it’s quite possible I’ll never need to use the spare tire. But I’d like to have one that holds pressure just in case. I decided to be better about the spare tire situation and inflated it the other day, and in 2 days it was flat again.
I used the soap bubble , and discovered it is leaking at the tire/rim interface along about 6-8 inches. What are my options? I don’t need this spare tire to be perfect as I’d only use it to limp home, at most 5 miles on surface streets 30 mph max. I’m thinking presently the only sol’n is to remove the tire and smooth whatever’s causing problems along the rim, then remount the tire. Are there any simpler solutions to this? I’ve also wondered if I could fix it by just keeping it inflated for a while, maybe a little overinflated even, and it might seal and fix itself. Is that a happening thing? Or over-optimistic?
