I will be putting inner tubes in my DB30 tires since air likes to leak out of them. I got my inner tubes in the mail today and I can't seem to get these tires off the rim. I used a pry bar and tried to break the bead, but it won't work and I am worried I will bend my rims more or puncture the tire. The tires themselves are half flat as is. I am considering using an air hammer and was wondering if that is a good idea. Does anyone else know a good way to get tires off a rim?
