Best way to keep going in snow or mud or ice.. is to have proper tires for the conditions AND to deflate to a lower psi (20-25psi seems to work best for me). And that's where the problem start with dually. You can't deflate them that low or the tires will rub between them. Rocks will also get caught there. Plus they are a pain to clean, lol. SRW also seem to track better than duallies.

But make sure you get a single tire with the proper load rating!

I’ve thought about it but the big concern is the weight limitation even on load range E tires on a big rig like ours.


I’m on a 6” Baja GG lift and I wouldn’t have cleanernce to run a 35” tire. Not without re-shaping the rear arch of the rear fender.

As for snow, drw will great with all that weight on the back axle! Here’s a video of me in CO last month bombing out of a lot I slept in.

Weight on the drive tires is huge something these rv vans don’t lack. The only big neg is rocks caught between the tires and destroying a tire/s.
Empty Pickups especially duel tire ones are horrendous given they float and have zero weight which case same truck on singles will be slightly better.
Out on the ranch we avoided Durl tire trucks because we often were dragging trailers around the ranch with an empty bed. We usually had skinny pizza cutter tires too so we could get bite on wet grass vs wide tires it was like trying to drive on an ice rink.

But these RV vans easily fix the problem by having good weight over the rears.

I can't tell if your tires are 235/85r16E tires or not, but I know a lot of vehicles with dual rear tires run them. Check out the BFG Commercial T/A Traction tires. See BFGoodrich Commercial T/A Traction Winter Tire - 235/85R16E for a better look at the tread.

I’m running 255/80R17 Cooper ST Maxx. Basically the same pizza cutter style tire you mentioned but in a 33x10.

When I looked into this I was unable to find a tire that could handle the weight without going to a 40" tall tire. I'm trying to stay with something like a 31" tall tire and the best I found was about 4,000 pounds per tire so 8,000 on the rear axle. I've decided to go the 235/85R16 route. Duallies look cool and they're more stable laterally.

I went with a set of Ricksons. Each tire is rated at about 6,500 pounds. 35" diameter and no trimming on an F550.

I wish BFG made the BFG Commercial T/A Traction tires for 17" and 18" rims.

I also miss the Wild Country TXR tires (NOT the TXR II). I ran 33x9.50R15 on my TJ Wrangler. Lots of sidewall, and they grabbed hard in the snow.

As long as one can grab the bottom, pizza cutter tires are great!

Check my links from one of my previous posts. BFG makes a good winter tire in the size you want.

I like your low profile flatbed. Did you build or buy? Manufacturer?

It really looks like there's turds coming out of the wheels. lol

I have designed it and had it built. It sits about 6" lower than a typical flatbed.

In my experience , duallies suck in snow, and I'm from Canada also, single narrow tires cut through better,, the duallies would float and spin, on gravel roads the blast rock has ruined a few of my tires with rocks getting stuck.. On this van I switched to 19.5" toyo m608z, 6500lbs rating if I remember correctly, haven't wheeled it to much yet, but I would never own a dually again unless highway only, with no snow,,

What are you driving? How loaded is it?
Fair point on the rocks. If I spent less time on pavement then changing would likely be a priority.
