I have an 2006 Artic Cat 400 4x4 auto
The existing tires are:
25x11-12 on Front
and 25x10-12 on the rear
When I measure the front stock rim it appears to be a 12x6 or 6.5 rim.. backspacing is like 3.5 or 3.75 inside, 2.5 or 2.75 outside - it's hard to measure.
The local CAT dealer couldn't say for sure because he thought the size was unusual... Although in the Artic Cat part guides the tire size is right... He thought it should be 25x8-12 on the front and 25x10-12 on the back.
The stock rim is stamped 12x6.5.
I'd like to take advantage of a set on eBay of 12x7 ITP with center caps & free shipping, that have 5+2 backspacing.. I think that means 5" inside, and 2" outside.
