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. Unlike ours that are machined to less than 30 thousandths of accuracy, Steel wheels are made inconsistently and the results speak for themselves. We have replaced many of these wheels for customers and will give you their contact information upon request.

 

The danger of steel wheels

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

Tire Options

Continental Tire has specially certified our wheel/tire application for 7400lbs. That is 9% above the original rating and is exclusively available for DBL Design. The tires options are:

335/80 R20 (42in)  Continental MPT 81 tires.

365/80 R20 (44in)  Continental MPT 81 tires.

 


DOT MANUFACTURERS IDENTIFICATION NUMBER IS 27529

The MPT 81 is the most common tire purchased for customers that spend a good amount of time on-road as well as off-road. These tires are quiet at speed, offer low rolling resistance, and do excellent in Sand, Snow, and the Rocks. In extreme mud the MPT 81 tends to have a hard time clearing itself and the MPT 80 is probably a better option. The MPT 81 is a direct competitor to the Michelin XZL.

Our company started with a simple idea. We took USA’s farm truck and strengthened it to make it into a world-class military platform. As it turns out, we weren’t the only ones who wanted these modifications. DBL Design wheels can currently be found all around the world; used by NATO and in military applications, brush trucks, and civilian use. DBL’s “Severe Duty” wheels and accessories set the bar for extreme duty everywhere.
