Well based on that, and having looked on the web for a while trying to find some, I may just replace the tubes and run on the old tires until I can come up with enough for a new set of rims. The tires should work for a while at least. The tread isn’t too bad on them, but the sidewalls are starting to crack up a little bit. I’ve never had tires do that to me before. Unless I just wore them out before it became a problem. Thanks!
