Brake pads against the tires?
 
Saw a bike today, chained up to a sign pole in Camden, NJ, USA. Wish I had brought my camera with me. The owner had reconditioned an old mountain bike. Frame was rattle-can painted so I didn't know what brand bike it was. Everything was clean and shiny. Just one thing seemed wrong - both front and rear brakes were adjusted so the pads would clamp down on the tire 1/4" to 1/2" above the rim. These were knobby tires and it looked like the top part of the pad would border on the edge of the lowest row of knobs. The pads were adjusted close to the tire and it looked like it would take little brake handle pressure to make contact - like with most brakepads over rims.

Has anyone seen this before?

maybe once or twice on rusted abandoned bikes donated to the local Co-op for salvage...

brake pads rubbing tire => tire failure

The Bikeforums member mantra, "Anyone can fix a bike". Looks like it is fixed. As a side benefit you know when you need to work on your brakes, because the tire fails.

saw it quite a bit when I worked as a bike mechanic.

I don't see why people can't fix their bikes themselves. I think a lot of people fail to take it seriously, and that's where the trouble comes in.

I haven't seen that. But on the $100 mountain bike I used to have, the brakes were pretty abysmal after a year, and I can see why someone would do that just trying to get it to stop.

Ha, maybe the figured tires were cheaper than rims so they'd just wear the rim out from braking. Honestly I am guessing they really just didn't know. We could always walk around with business cards that have Sheldon Brown's URL on it and leave it on bikes like that.

Yeah. I should have left a note on the bike. I spent three hours in the building and as I was walking out the front door, I saw the owner down the street riding away, but too late to talk to him.

He must be using those special "rubber compatible" pads!

Heh... don't worry. He'll learn his lesson quick, just like I did.

Early in the commuting career, I had to change a tire after running over a tack. Since it was flat, it came off the frame real easy. But after re-inflating it with the new tube, I couldn't get it past the brakes.

Stupidly, I ignored/forgot about the quick release thingie, and just whanged the thing through and back into place.

For the next few commutes, I wondered about the funny noise my front brake was now making, but since it appeared to be stopping me fine, I ignored it.

It was harder to ignore when the tire let go with an audible report when I hit the brakes going down a decent-sized hill next to my work. Yeah. That's some good homestyle bike maintenance right there. Quality wrenchin'.

This kind of mistake will only be made once...
