you're right, they do suck, but if you use your truck as a truck, taking the tire out of the bed every time is also a PITA.

BTW, you can extend the depth of the tire carrier by cutting off the old pieces, and welding in 5/8" round stock to extend the length for wider tires.

Considering how mine (doesn't) fits, I imagine larger diameter tire within reason would fit also.

I still say the best tire carrier for the F-series is the full size bronco carrier. That reminds me, I need to install mine one of these days.
