Does anyone have an opinion about these tires. I saw these tires at a local Artic Cat dealer and found them to be extremely aggressive looking compared to the stock tires or ITP Mud XTPs?

The other question from a newbie Artic Cat 700 LE owner, I want to put 27 inch tires on my 25x8-12 and 25x10-12 stock aluminum rims, is this possible or go with the 26's.

Thanks for any input.
