can i run on a rear raptor tire,that is backwards? just for a weekend?

 

If you ride hard,.... I'd not do that.

Why not flip it around? Relatively easy. Especially since they are at least 9" rims. (unless you have aftermarket smaller rims on it)

Harbor freight sells two different bead breaker tools that would do the job. They are less than 50 bucks each. One better than the other.... Normal stuff. This is the better one. It's specifically for smaller tires/wheels.

- Harbor Freight Tools - Quality Tools at the Lowest Prices

Usually in stock at my local HF.

 

What do you mean backwards? You mean the tire is backwards on the rim? Or the rim/tire are mounted backwards on the machine?
