Biggest size tire you have or know will fit on your trike.

I just totally lost it and purchased 2 sets of enormous mud tires for the 350x and the 250sx. On the 350x they are getting 26x12x12 Gateway Outlaws (highlifter tires) On the 250sx are going some 26x9.5x12's Super swamper vampires. Got both sets for cheap. So I will soon let you guys know if they fit and I will have some pics. Now I need to find some cheap 12 inch honda rims.

When I bought my 350X, it had a pair 25/9/12 Gateway Buckshot Mudders on the rear. See the pic. Sucked huge! The gearing was way off...not bottom end at all. It got a set of 20" Holeshots and I have not looked back since!

26" on an SX? Hope you have some wheel spacers or the exhaust removed. Might rub a bit.
