Low-Buck Spare Tire Mount

Ranch Raptor’s Secure Spare

By Fred Williams, Photography by Fred Williams

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.

  • Our supplies included a 2x3⁄16-inch steel strap, a 2-inch pipe with threaded ends and a screw-on base, angle iron, a 3⁄4x9-inch bolt, and a bunch of 3⁄8-inch bolts, washers, and nuts. 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.
