I have 10" rear wheels on my 2009 Outlaw IRS, I am wondering if 9" wheels would be better for XC. The sidewalls on the tires really seem to get ripped up, I wonder if it has anything to do with the shorter sidewalls. There also seems to be a better selection of tires for 9" rims too.

More tire = more give for cushion, but more flex for bad handling.
I'd take the 9's. My 09 has the 10's on it too.

The sidewalls tear up due to air pressure and quality of tire. The stockers do not have the best sidewalls IMO. Run at least 5 psi in the rears in rocky conditions. I run 10 in the fronts.

well I figured that the 10 inch rims would be more likely to get pinch flats from rocks. I rode for a week at hatfield McCoy last summer and really gouged up the sidewalls there. I think I may get a set of different tires and wheels for the trip next year as the rocks ate a lot of tread off the tires. Anyway, any other pros/cons for either size?

Were you running the stock tires? Hiper only made a 10" for the IRS and I never had any issues with pinch flats on them. I ran Razr 2 6 plys all year last year. Like I said,your air pressure has a lot to do with flats.
