SUPER SINGLE WHEELS AND TIRES
For use on Ford F-550, F-450, RAM 4500, and 5500
DBL SEVERE DUTY Wheel Design
With the most extreme conditions in mind, our wheels are engineered to support 11,000lbs and withstand heavy abuse. Our all American design has helped thousands of customers around the world experience military quality at an unbeatable price. Three-piece forged aluminum 20 x 10, with powder coated steel plate centers, all manufactured with the F-550 reversible bolt pattern.
Please be careful not to order steel wheels for the F550 super single conversion. These are agriculture shells and are not manufactured to the precision required for highway speeds. Because the weld is forced to bear the load pinched between a flat plate and the shell, they may crack over time while ours remain strong. The shells will warp or wobble because they are not manufactured for the weight capacity of the F550 rear axle. We have replaced dozens of these wheels for customers and will give you their contact information upon request.

The red area in the stress analysis above indicates the location of the highest pressure. All of the weight is held by the welds instead of being dispersed in a pressed plate.
