so i reckonmend taking them to a shop or if you do it yourself use dishwashing liquid an lube it up as much as you can to pop it off an on easyer dont use oil to lube it up cause you cant wash it off an it stays in the rim an when you ride it the excess oil will make the tyre spin on the rim an pop tubes
lube & the right technique is the key to 10" pile-o-crap tyre changing... & be prepair'd to work up a sweat!
