Been a big rig fan since watching Will and Sonny every week in that KW W925VIP.

Just never notice a tractor with that many axles. Some of the concrete pump rigs running around have a bunch of axles.

Quite common.

First time out of the house in a while ?

"Jake Leg", ie; tandem steering axles.

Off topic but around here everyone is running Super Singles and getting rid of the dually wheels on the tractors and trailers.

It was mentioned above the cost is about the same but it saves on weight. I have also been told its a tax thing. There is a very high tax on truck wheels and they can cut that number of wheels down significantly and in turn cut cost.

Learn something new every day, seems the tax law was changed. The tax was the same due to it was based on load, but now you are correct it has changed. The great thing is they save a lot of weight and runbber, the bad is the ones I have seen suck in the snow and ice.

Tire Business - Log In

A new method of calculating federal excise tax (FET) on tires was included in the American Jobs Creation Act passed in October. Previously, the method for calculating FET on tires was based on the actual weight of the tire. For every 10 pounds of weight above 90 pounds, there was a charge of 50 cents, plus a flat fee of $10.50. Thus a tire weighing 118.63 pounds carried a tax liability of $24.81.

The new FET is based on the load-carrying capacity of the tire. For every 10-pound increment in load-carrying capacity above 3,500 pounds, a tax of 9.45 cents is levied. So, for a tire with a load carrying capacity of 6,175 pounds, a fleet would pay $25.27 in tax. Super single tires, however, are to be taxed at the same rate as bias ply tires, which is 4.725 cents for every 10-pound increment in load carrying capacity.

This gives super single tires a great advantage in the marketplace since taxes are cut in half and, since one tire replaces two, users of super singles will get a real deal in the tax department.

We ran about the same tire as a super single back in the 70's on a mach l Mustang. No tax credit then...

this is a 64 ton truck by dutch construction truck maker Ginaf, sold to a quarry in Austria. It is based on a standard road truck which is legislated to 50t GVW (46t in the rest of Europe) so the components are off-the-shelf and therefor cheaper.

Meanwhile they have also made an 80t GVW truck with a 60t capacity, which is tagged at 50t so it can still drive half full over the public roads: However it is intended for large earthmoving projects at closed courses. Fuel consumption, tire cost, purchase cost are much more favourable than ADT's, however the trade-off is lesser offroad capability..
