Glad to be of assistance. Also check out ITP Mudlites to.

 

I have Kenda BearClaw 25x12,5 rear tires on my Ozark. I have also raised front and rear suspension about 1 inch.

 

...and the clutch is o.k? since when you have had them?
Thanx

 

Yes, the clutch is ok, why shouldn't it be? The outer diamater of the tires aren't much bigger than stock, since they "get flat" when mounted. From behind they almost looks like barrels.
I've had them on for about 2,5 years now.
Rode 60 kilometers terrain yesterday and got stuck once (my friends Sportsman 500 got stuck in the same spot) I think the grip is awesome.
I will post pictures.
