I don't know if this pertains to the thread, but I ran into a tire width issue when I put massive tires under the truck. Fortunately, I already had the stock "swing&drop" carrier under the truck, but the threaded rod and hook were too short and the wider rubber wouldn't fit. I took the hanger hardware off the frame and went to Tacoma Screw, they gave me threaded rods 2" longer than the rusty originals. I bolted the diagonal "saddle" to the new rods and now it holds the oversized rubber like it was designed for it (the bottom of the saddle is barely above the bottom edge of the pumpkin). I doubt you could do this with the earlier slide-out carriers (although Russ' design will take any size), so I prefer the swing-out carrier.
