I just measured the back spacing on the rims -- fronts and rears comparatively between the stock wheels and the can am wheels.
The backspacing is about 3/8 inch more on the can am wheels so it looks like I could go with the 1 1/2 inch adapters and gain just a little over 2 inches in extra with.
The fronts tires are 27 x 9 x 14 and the rears are 27 x 11 x 14.
Is 2 inches of extra width going to be enough or should I just spring for new rims ?
