Off Roading Traction?

[50BMG]

Question which provides more traction a super single tires or duallys in a deuce and a half ? Thanks in advance for any and all thoughts, opinions, and answers.

Super Single, always.
That's why all military Vehicle are setup that way.
Also you can't air-down a dually setup to what's needed especially on soft terrain.

Super single because it gives more Contact Patch and Yes you can air them down easier .

What's a "Super Single"...?

 

[Simplysmn]

Super singles are the super wide tire that the Military truck's have gone too instead of running Dual wheel's .They run 1 double wide tire that hold's the same weight as dual's .

I think you'll find the the over the road trucks that are running one tire on tractor drive and or trailer axles also go by the term Super Single.

I know in Snow conditions I have seen and experienced duals perform better than super singles. The reason is the duals have to "plow" less snow away from the front of the tire as compared to super singles. On a heavy vehicle in snow, a tall skinny tire cuts through the snow.

In the world of big rigs, duals are the standard. They also have a minor safety advantage of allowing the vehicle to remain in control and mobile enough to pull off to the side of the road, if one of the tires has a blow-out. Super singles are favored in applications where maximum load capacity is required. By law, most states limit big rigs to gross 80,000lbs. To carry more weight, you have to reduce the weight of the truck. Super singles are capable of carrying as much weight as standard duals, but duals tend to be heavier. The super single design, along with other weight saving components allow some trucks to carry more physical weight without exceeding the max gross limit.

In an off road application single tires tend to have more advantages than duals. For one, it's difficult to go wider with duals. Space between the tires need to be maintained to prevent wearing out the sidewalls, especially as you air down. Also, mud and other off road debris, can pack up between the tires and rims, greatly increasing unsprung weight and causing severe unbalance. Tire maintenance is also increased with duals. Tires should be at equal pressure at all times.

Depends on the terrain. Bottomless mud, the singles would be better, but if you need to cut to the hard bottom, then singles, also singles not good on road in winter conditions. If you have a flat with a single, much harder to limp to safety than with duals.

Up here, singles run about 5% more fuel mileage, but more expensive to replace than two singles and terrible in winter
