How does Ford get away with five lugs on these heavy duty vans. I see they spread the studs/lug nuts further to the outside of the hubs. Is that enough clamping force by doing this alone?

Stud size?

It must be a big money saver..

That is different for a vehicle with the weight ratings these have :s

In the end I trust that the Ford engineers :nerd: know more about physics than I do and have confidence that they did not cheat on the figures.

There are more factors that contribute to the capacity of a wheel than the number of studs alone.

BTW, the old 1/2, 3/4, 1 ton scheme does not apply to the Transit 150, 250, 350. Their payload capacities are much higher. For example, the payload on my 250 van is around 3600 pounds, well above 1 1/2 tons.

The old 1/2, 3/4, 1 ton thing does not apply to ANY modern vehicle I'm aware of. My 350HD would be marketed at a 2 1/8 ton if it did.

As for number of studs needed it is influenced by stud size, stud strength, lug nut configuration, wheel strength, whether the wheel is hub piloted and probably a couple of other things I couldn't think of in 30 seconds.

The same way that NASCAR now gets by with just 4 lugs nuts on their wheels.

I wonder what the sprinter has? 6 lug?

The 150, 250 & 350 (non dual wheel) use the same tires, wheels, & brakes. The rear springs are different stock #'s but the look the same (maybe different steel).

Sprinter T1N's (2002-2006) had 5 lugs, torqued to 177ft lbs on steel wheels. Everything newer has 6. Good metallurgy and also keep in mind that the lugs only hold a fraction of the weight; their purpose is to hold the wheel tight to the hub. It's the flange on the hub that fits into the hole in the center of the wheel that holds the weight.

MY 14,000 lb. Fuso has 5 lugs, ain't no thing...

 

[hammerdown]

That Fuso IS AWESOME!

I believe Katman is correct having looked into this a while back.
Ford gets many $$$ extra for a T350 over a 250 or 150.
The only difference (other than the badge) seems to be the spring rates.
Nice and profitable!
