In the front and rear wheels? What allows the fronts to fit the rear but not the other way?

 

[rocknroll]

The rear wheels are wider than the fronts and the back side of the rear wheel is too deep to fit on the front.

thats why i only carry fronts as spares so i can fit both my ranger and sportsman when we go riding

Do you think after market wheels, ITP Hurricane or similar in 12X7 would need spacers on the front?

 

[rocknroll]

Probably no. Most aftermarket wheels are 4+3 backspacing.

It is usually the tire width that is the issue, not the rims. Aftermarket rims may work if the offset is deep enough though.
