Johnnyboy my rims are 12x10 with the 5 x 4.5 bolt pattern. On the distance from the center mounting surface (where the hub meet the rim) to the very outer edge of the lip is 5 3/4 inches. When I get to the office tomorrow I'll scan an illustration and post it.

thanks buddy, but for some reason i can't pull up the illustration. is the 5 3/4'' measurement to the front of the rim ( if your facing the wheel ) ? i need the measurement to the rim edge if your facing the back of the wheel . thanks , j.b.

rim dimensions (1).jpgThe measurement is on the inside of the rim, or the tub side. Try this image.

that's it. thanks a bunch. i wanted to see if the rim and tire would clear my front drive chain. my chains are outside the tub. j.s.

The tires appear to be Kenda Bear Claws. I have a set that I got with an amphib, but the tires are not swimmers, at all. They do perform well in the mud, and I transferred the tires to a four wheeler and have two backups.

A Hustler 980 tall tub is a good find. Congrats on that. The old Kohler 18hps were very much under rated, I always thought they had the power and torque of a 23hp engine. The Kohler will tune well too.

They are GBC Gators. 26x12x12. The deep lug looks like they should swim pretty good, but only time will tell.

So I still haven't touched my new to me machine, but look what I ran across yesterday. I think the this would be a good modification for the 980.

Gators do swim, they are not fast, but swim ok, and mud really well.
