Low-Buck Spare Tire Mount - 4-Wheel & Off-Road Magazine

Fred Williams Brand Manager, Petersen’s 4Wheel & Off Road

BluFerd, our ’79 Ranch Raptor (aka F-150) is a good truck, but even though it’s shod with the tough General Grabbers we’d hate to walk home from the back forty if we ever encounter a flat tire. We mounted up a fifth 35-inch Grabber on a 15x8 Mickey Thompson Sidebiter as a spare tire and in an afternoon wrangled a homebrew bedside mount for the big rubber.

Our goal was simple: Head to the local farm supply hardware store and come home with parts to build a simple yet tough mount for the spare, all while keeping bed space open for hauling lumber, logs, bales, and hogs. Mounting the spare underneath is a good option, but many larger tires don’t fit in the stock location. As a challenge we wanted to see if we could do it without the welder or tube bender, as many readers don’t have those higher-dollar tools. Here’s what we came up with for under $50. You could probably do it even cheaper.

Tools include a tape measure, an Ingersoll Rand cordless drill, a Harbor Freight Tools step drill bit, a Kobalt hammer from Lowes, Craftsmen wrenches, and a way to cut metal like a hack, chop, or reciprocating saw. We had to bend the 2-inch strap so we put in a vise and pounded it over with the hammer. An anvil, bumper, or heavy work bench mixed with a stong C-clamp could work the same. The angle iron gets cut to 11 inches, and 43⁄8-inch holes are drilled as shown. The 2-inch strap is cut to match the floor-to-bedrail height and gets two holes for the floor and two to match the center of the angle iron. We matched the holes in the bracket to the bedrail and the floor of the truck. After a coat of primer and paint we were ready to bolt the bracket in place (use washers on both sides). We added a 3⁄4-inch hole in line with the center of the wheel and slid in the 9-inch bolt. Note the 1⁄4-inch hole in the end of the bolt for a padlock. The pipe was threaded into the base plate and cut down to about 7 inches total. The pipe slides through the wheel center and over the 9-inch bolt with the base plate secure against the wheel center. Two washers, a nut, and a padlock secure the tire from bouncing away while we’re exploring rough pastures.
