mountain bike tire question

You have tubes in your dirt tack tire ?

 

That was what has me a bit confused. At 60PSI there is a fuckton of pressure on the bead and it should not be slipping. I guarantee it is the correct size for the rim too. They are both 26". We are still old school.

The low pressure on race tires still messes with me a bit. I was away from roadracing for several years and almost shit myself the first time Mr. Hirsch told me that I needed to run 20-22PSI on the rear tire.

 

I had thought of that and the bead to rim gap did not seem excessive. I had checked that previously by comparing it to my bike which does not have this problem at all and they looked about the same.

 

Odd, I would try that glue I posted.

 

Xr100. Yes.

 

Without a rim lock or screws ?

 

I'm not sure I've ever used the rim lock on it. Definitely no screw. It's been a while but I can't ever remember fiddling with a rim lock on one. And thinking about it, most of the time they're already gone on the xrs I've gotten. Never chalked a tire to see how much it moves. My guess is the tire just slides around the rim. @Robby-Bobby probably knows more. I was a hack doing it for fun. But I do know hire to makes things really slippery.

 

It's been a long time since I raced dirt bikes.
Can't remember what pressure I ran, but I know in mud and sand it was pretty low.
I removed my rim locks and installed screws.
