Super Wide Singles

Then they would cost as much as a real truck.

I was just noticing the 4 wheel drive on this truck. If the rear tires are more than about 3/8" taller than the front tires, there could be problems in the sand. On ice and snow, then the rear tires can easily spin faster than the front ones, and not cause a huge problem, but in sand, the center differential can cause problems if trying to spin the rear tires say 625 times per mile while the stock diameter front tires are spinning 665 times per mile.

I hope they are the same diameter! It looks that way. But a string around the outside of each tire, and making sure that they are within about 1/2" (outside diameter length) is the only way to make sure there will not be center differential damage.

They do make super singles for the 19.5" rims and some are rated well above 7,000 pounds required for a 'dually' pickup. The 4X4 F-650 has super singles on them (aftermarket) and are huge, with treads about 1.5" deep! They look about 15" wide.

The super singles in the picture at the top on the blue class 8 truck are probably rated around 10,000 pounds each, to match up with the normal 34,000 pound axle rating for the two rear axles. (Combined 2 axe weight rating is normally about 34,000 pounds on a class 8 truck).

Cement trucks have been using super singles for many years.

Those super singles you are talking about only come in 22.5 rims. They save fuel, which is why truckers use them. I have heard complaints about hydroplaning in the rain. The cost is actually less than buying 2 tires on the big rig. After the initial cost of buying 4 new rims to hold the tires, there is a cost savings.

I would imagine one of the reasons no air ride seats is the air compressor. A big rig uses air for a multitude of reasons(brakes, works the splitter on the transmission, supply the trailer with air, etc.) If the oem's would put a built in compressor like a big rig, it would make sense to air ride the seat.

That's a sexy-looking truck! Looks like it's ready for the quarter-mile ;-)

Also since many complain about the stiff ride from a 1 ton truck; I'm surprised the OEM's don't put airbags under the seats or cab like they do on semi trucks. I'd also like to see them take some design ideas from semi truck frames and apply them to the flimsy pickup frames so they can have some real hauling capacity.

Maybe it's the P rated tires? Or the light duty wheel ratings? Or the car axles they put in them?

For the asking price of a new truck; they really should offer a lot more.
