ASK THE BMXPerts: TIRE TROUBLES
Bookmark and Share

Q: I just bought a new Verde bike and when I 180, the bike tire pops out of the rim a little. If I leave it, it gets bigger so I have to keep deflating and pushing it back in the rim, then reinflating it. What is the matter with the back tire?

A: This could be your tire, or it could just as easily be a few other things, so run down this checklist with us before you buy a new tire. Take note of the spot the tire pops off at and mark it on both the tire and the rim with a piece of chalk. Now air down your tire, turn it a half turn on the rim, air it back up and note where it pops off the next time. If it pops off at the same spot as the chalk mark on the tire, you have a bad tire. This could be a defect, but if you are side loading 180’s all day long, we wouldn’t be surprised if you damaged the bead and simply need a new tire and should run more air pressure in it next time. On the other hand, if the tire pops off at the same place as the chalk mark on the rim, the rim is the problem. Start by checking to make sure that you don’t have dirt under the lip of the rim, or that the rim strip hasn’t shifted over to prevent the tire from completely seating. If neither are the case, then have your local shop check it out, provided you don’t have a dent or a flat spot in your rim at the spot in question, they will either fix it, or replace it for you. And go easy on the air pressure until you sort this out, you don’t need a tube blowing up in your face. Good luck.
