The 25" bear claw might have 3/4" lugs(just a guess),I've had them and they are a very good all around tire but I would look into the 26",they have deeper lugs,you have the power.

 

I have 27'' Bearclaws on my 400, and it seems to turn them fine. The lugs on the rear are about 15/16", the fronts are a little smaller. You'll notice a big difference in the handling with these tires, and I must say, they're tough as nails. They offer good rim protection too. For an all around tire, they're hard to beat.
