Researching the net. I read that the 1.5's would be a bit too much and a lot stress on the hubs and bearings. I had liked the width of running ITP wheels, so when I switched back to stock all that was needed was 1" spacers to make it the same width.
Copy and past this link.
Right after the Ruler pictures and the stack of 4 tires. Are pictures of my spacers and the install.
It's personal preferance. 1.5 inch isn't going to do any more damage than 1 inch spacers. I had 2.5 inch spacers on my Raptor with that spindeley thin axle and didn't do any damage.
When you put after market rims on you're doing the same thing. You're moving the tire footprint farther out from the center of the machine. Your hubs are still in the same place, so what's the differance.
