Duals on the front of a pickup serve no purpose. The front axle is well under the max weight carrying capacity of the stock 2 front wheels and tires. It's also a great way to destroy the ball joints and wheel bearings, break an axle u-joint and prematurely wear out the tie rod ends, as well as wearing out 2 more tires unnecessarily.
The GM "Futureliners" had dual front tires too - back in 1937. Back then, they did not have 6,000 pound rated tires that we have today. And the Futureliner designers did not move the rear axle far enough forward to carry 65% of the overall weight.
There are a few tractors that have dual tires on the front axle, with some models having three tires on each side. One really big tractor used the "747" horsepower 16V92 engine in it, with 1,472 cubic inches!
I would rather have some 435-40-17's or some such size equal than duals! Same width, but better traction all around in ALL conditions.
Altho a kewl pic none the less.
I found a few real tires: Coker's Pro-Trac still has 515/45-15, at 32.8" diameter by 17.2" of tread width, OR Pirelli has a 385/35R24 at 34.6" diameter, that requires wheels 13-15" wide, rated to 2760# each.
Both are fully treaded for rain use, but the 515s are known to hydroplane like no dually ever has.

Useless P.O.S. that some pimply faced "Look at me!!" type will be drooling after...That should be able to break front spindles at will. I bet it has a loud stereo and straightpipes too...I guess you can see I'm not too impressed.
