Ok, I just bought my new 2010 4x4 420 Rancher with power steering, ES, and soild rear axel I love the ATV and hate the ugly/cheap factory rims. I need some help on buying new wheels I find custom 12x7 front and rear wheels listed for my model but my factory wheels are 12"on the front and 11" on the rear? Does this matter is it Ok to go 12"s all the way around? Any extra tips you guys can give me would be great on wheels and tire buying for this ATV I am new to this whole game. Thanks!
