After some short mud rides on my new 850 X-MR I can’t help but think that a set of wider rear tires would help me bear up on muskeg type bog a lot better.

I know the 850 X-MR has 9" wide Silverbacks all around (30x9x14). I was thinking I would go with:

1. 2 New matching SS312 rims with 11" wide Silverbacks on the rear (30x11x14). (This would allow me to keep the original 2 rear tires in case of front wheel tire/wheel damage.)

Will this new fatter rear tire fit?

I only ask as this seems like much too simple a fix to me. 🙂
