25x8-12 and 25x10-12... hopefully tomorrow I’m putting some 27x9-12 and 27x12-12 Mudzillas on. I found a set local to me and picked them up for $20. Have about half tread, they’ll last until I go to buy Outlaw 3s
Got the 27s on and broke a rear axle almost immediately (shaft too short.) That didn’t stop me from riding though! My 3 wheel drive Grizzly was holding its own against a brute force 750 on 27” Mega Mayhems, and a Foreman 500 on 29.5 Outlaw 2s.
