Wanting to put 27 x12x12 on all four corners of my 09 650 xt outlander for my gf in the snow but im not sure what wheel and backspacing i need to make this work and the same question for an 09 sportsman xp 850 but im gonna put 28 x12x14s on it... anybody with any info on doing this to either of these would be appreciated

 

go with 14inch rim....i just received mine in mail...they are sick...completely change look and ride...i feel like a monster truck, riding over anything in my way..i didnt get crazy and run all 4 the same size like u r..i would be curious to see that and how it worked out..i cant imagine turning a 12x12 would be fun
