Dirt worthy wheel and tire options for heavier campers

What's wrong with the wheels? Can I air these tires down?
Not 'technically' able to air down. ATW trucks use them and swear by it, but no safety beads on 19.5 rims.

Have to find a weird *** offset 19.5 to run as a single (I guess you could just run an outer?). Also my current wheels are too skinny for anything bigger than a 225 width.... I dont think Das Bus's 6.75" are wide enough for a 285 either. EDIT: yes, Toyo wants a 7.5-9" wheel for a 285, 8.25" ideally.

Good to know. Have you been in soft sand yet? I'd like to be able to camp on the beach in Baja. I only got my Motovan stuck in the sand once on the beach last trip. It was easy to pull out the next morning with a fisherman's F150.
Yeah, along the river, and with two tires on each side there is such a wide footprint it just doesn't seem to sink. I would not even think about going to singles on the rear. I was worried about the front end, but it seems as if 265 is wide enough to keep it afloat


Das Bus is running Toyo M-608 in 285/70 R19.5 on 6.75" wide American Force wheels. I think I'll be light enough that I could just run those as singles in the rear. Toyo rates them for 6395 pounds as a single, that exceeds my axle capacity. It's 35.4" tall with 21/32s tread depth. This could work for me. 285 is wide enough I think.
Again, given what my experiences have been, I think going with 19.5 and paying for custom wheels would be nothing but a waste of time and resources. Not to mention that having some sort of custom, one off set up that is uncommon when traveling in remote areas is a BAD idea. Ford box trucks are everywhere, and I'm guessing you could get a 16" replacement wheel ( and certainly a 265/75–16) in San Felipe...or most anywhere else... if needed.

Also, running 6 tires reduces the need to carry spares in some situations.

Very good points. I'm going to test it out a bit more as is before I modify anything. I plan to build out most of the box first anyway. It has 6 good all terrains right now, not very aggressive though. Would you share some close up pictures of your rear wheels and the space between them?

255/85R16 on the rears and 285/75R16 up front would really be sweet, same height.
Yup, would be cool. However, 255s are gonna be an oddball size NOT widely available in backwater places, and a 285 is too wide for your skinny little 6" dually front wheel. Which means removing dually adapter hub up front and installing a conventional hub, so you can fit an 8 inch wide wheel. Which means you now have to carry two different spare tires. And there would only be about 3/4" difference in ground clearance and front tread width. Not enough difference to outweigh the downsides.

As you can see, I've already thought this through.

Sorry, no pictures. I'm currently on a fishing boat in the Bering Sea, and not near my bus

I'm working on a GMC Topkick based camper. I want to use 335/80R20 tires, for all the good reasons.
Having trouble finding wheels though. Does anybody know of any reputable wheel builders they could recommend please ?
I would really like to find someone that uses "dished centers" rather than flat plate, as this would make the wheels much stronger.
I would prefer not to use bead lock rims, to avoid cost, etc.
Thanks in advance.

Stazworks will dish their custom wheels.

Did you ever figure out your wheels/tires. I’m doing the same with the topkick as well as one other on the forum.

No. I haven't found anything reasonably sized and priced. Also, I'm still considering WeldTec Designs long travel vs a 4WD conversion. I'm still pretty far from the decision deadline.
