    Close call there. Get 10" rims if you can.

    No one makes a 10" rim for the 16.5" size. Its just a 9.75".
    I have run 39" Mickeys with 9.75" rims. Those Mickeys were like 15" wide. I have pics of this truck posted somewhere in this forum. It worked good too.
    BTW, a 9.75 rim for your 14.5 wide tires would work better than a 12" wide rim. The narrower rim will keep the beads seated better at lower pressure than a 12". 16.5's have no safety beads, so a wider rim will pop off easier than a narrower rim when aired down.

    Years ago, when I managed a Goodyear store, we were told that you should keep the tires to within 4" of rim width...all fractions aside, you are close enough for it not to matter....I just wouldn't run anything wider....it'll fit, but uneven wear becomes an issue....true, 16.5's are not a safety bead, so lower pressures will unseat themselves....you may consider switching to a 16" aftermarket rim/tire combo for more flexibility in the way you could use your tires when wheelin'.....just an opinion....JD

    I ran 10 inch wide tires with 14.50 tires before and it was fine. 9.75 is so close to 10, that I'm sure that will be fine too.

    Do you already have the tires?
    If you don't, go for the 16" setup.

    I'm sure that'll work considering I ran 16.50 inch wide tires on 10 inch rims... never broke the bead never had a problem... loved the fact the tire stuck out and protected the edge of the rim to from getting thrashed...!

    I've got a set of 35x12.5's mounted on some 6.75" factory steel rims. Near 40,000 miles on em without any weird wear patterns...

    The 9.75" rims will be fine. I run 9.75" wheels with 14.5" Swampers and they're fine plus the wheel is protected from rocks a little more. Good luck finding a 38.5" tire that mounts on a 16" rim. The only maker I know of is M/T and Parnelli Jones. Interco might make some at the end of this year. You won't have to grind with 16" wheels though.

    Does it look stupid to have that much tire buldge from a skinny rim/wide tire? Haven't seen it.

    The recommended rim size for my 15-39.5/15s is a 15 x 10.
