I think I should just get some tires that don't ned tubes. I really don't have the money to be constantly paying the man at the bike shoppe to replace the tubes and I can't do it myself with a disabled hand. it's too complicated and frustrating a hassle. could I just buy tubeless tires or would I have to get new rims too or what? I saw these tires on Amazon which had good ratings as being nearly puncture-proof but I don't know if i could use those on my type of bike
