Recent new family member, 2021 RAM Rebel, arrived with Goodyear LT275/70R18/Es on 8x18 wheels. Removing, changing, rotating these monsters puts a serious strain on my aging back, so decided a mechanical assist was necessary to enable my DIY habits. Browsed the interweb, saw a couple ideas, but nothing I really liked. Put together a design concept using an old HF floor jack and mostly scrap metal.
Parts: 1.5" punched square tube, U channel, 4 roller end plates, 2 rollers, an "L" bracket bolted to the jack saddle using the saddle bolt plus 2 supporting bolts, and of course the floor jack. The assembly can be removed and the saddle plate/pad replaced to return the floor jack to conventional use. Here's the parts and a pic of the jack saddle with "L" bracket. Note the 45deg cuts on the tube. Project cost: $25 for the rollers.


Below is a mockup of the design. The square tube is welded to the floor jack "L" bracket. The two U channel arms are welded to the tube at a 45deg angle to support the rollers. The inside (closest to jack) roller plate is welded, the outside plate is bolted on so the rollers can be removed/replaced if necessary.


Below is finished assembly and maiden voyage. The arms/roller spacing is such that the tire can be lowered to the ground, freeing up the tire and/or the floor jack/tire lift. The rollers allow the wheel to be easily rotated to line up the wheel studs with lug nut openings. Very pleased with how this turned out and my back is happy
