Who says you gotta have 18 wheels? Super singles are the new "10 wheeler".

Probably just ruined a bunch of songs, didn't I.

Still haven't seen these in person.

I've seem them on tankers mostly. They weigh less so you can fit more cargo and be under the 80k limit.

Some trucks looks like this in the rear because of theses tires. They we're designed to get double tires at first.

A couple of companies around me run them. See a lot on I-40.

Didn't think about that...

When they first made an appearance I was skeptical of their water dispersion and snow traction capabilities compared to the duels.

The biggest drawback is really if one blows there's no paired tire to take the load. So it just goes down. The second biggest draw back is that they're not as common so it's harder to find a tire shop that has them in stock at o'dark thirty at night.

I hope they are safe...

Dual wheels aren't for looks. they are for having twice as many tire sidewalls and wheels holding the weight of the truck up.

If half as many sidewalls and wheels per inch of tread width is safe... good for them.

But a blow out is going to be more of a problem, if/when it happens.

Reducing redundancy is a way to cut weight... but does it cut capacity or safety, is the question.

When you blow a tire on a dually, you often do not know it until you see it shred itself. I would assume with a single you will know right away. I'm pretty sure that the main purpose of the single is weight reduction as the cost of a tire is about twice that of a single.

Dual wheels are for load capacity. Tires have come a long way since duals were implemented.

There are still physical limitations to a sidewall, and to the disc and barrel of a wheel.

Technology has advanced, but it hasn't negated the law of gravity that gives mass weight.

Such a wide wheel barrel, on one disk, and one set of lugs is taking the load that TWO used to bear.

Plus, the center of such a wide tire is likely much less supported if the tire runs over debris in the road. A dual has a much more rigid, narrow tire tread for each, and it is supported by a double inboard sidewall.

If there are trucks where duals are way over-kill for the weight load design, I can see where a super single would be fine, and a way to run a lighter rolling assembly. A straight truck, maybe a car towing roll-back, a box-body truck, with just 3-4 tons of cargo weight... duals may indeed be overkill.

Maybe they are actually safe under maximum road allowable weight... but if a tractor-trailer is pushing maximum legal weight, especially at sustained high speeds, I would hope very much that they are damn sure those wheels and tires are up to the task, and that the vehicle would still be stable if one of them blew... because truck tires are known to do that... and one blow-out of a super single, is like losing BOTH tires of a dual setup, simultaneously.

So you're saying this would be the best?

For snow and bogs and stuff, maybe.

I am not sure that would hold up the weight of a tractor-trailer, and would likely induce a lot of drag.

I don't see them much on the Prairies, but in the Vancouver, BC area I saw them all the time, primarily on gravel and dual-steer axle concrete trucks, but also on regular OTR trucks. I guess it all depends on local markets and DOT/MOT codes.

It would take forever to get to the destination, but it definitely *would* get to the destination.
