Paddle tires on Brute force ATV?

[rysondark]

Im currently got 08 KAWASAKI, BRUTE FORCE 650i

I was looking in rockymountainatv.com website and want to get some paddle tires for my atv but theres two kinds that showed up and i read their customer review and none of them are really good. (AMS Aerospeed and ITP Dune Star)

I really like Skat-Trak sand tires and my stock tires size is 25x10x12 but here my questions are:

what kind of sizes of wheels that brute force can fit for the rear?

what kind of tires size that can do just fine on the rims for brute force?

will the Skat Trak extreme paddle tires with size of 23x10.5x12 will do just fine on the stock rims of 25x10x12?

on the site, they show the wheel size of 12x7..what does that means?
