thanks i was not surefytattoo said:i agree....i had 33x12 with stock backspacing and i felt like that was tippy...once i went to the 13.5's with 2 inch backspacing it is way more stable on the trail...i couldnt imagaine a 10.5 tire on the trail..a 12 or 12.5 inch with stock backspaced rims will fit fine under the wheel wells
