I have a 1982 250r ATC. I want to get new tires for the rear. The stock one (or the ones on there now) are 22x11.00x8 I am looking at the 22x11x10 or 22x11x9 Kind of want the same size or close, but more flate, not round, like the ones on there now. Also, what is the biggest rim that could fit on the front? 9x9 or 10x10 or 8x8 (stock)

Thanks,

Ron
