I've looked in vain for the definitive answer to the question of what wheels will fit dentside one-ton trucks with dual wheels. I've recently acquired a 1977 F350 with the 16.5 inch wheels. I've seen a '79 F350 dually with 16s. Did Ford make both sizes for the one-ton dually trucks of this vintage? Will the 80s 16s fit correctly--backspacing, hub bore, brake clearance? I would love to get 16s to fit so my tire options are not so limited. Does anybody make good aftermarket steel wheels that would work? Any advice would be appreciated. Thank you.

 

Welcome to FTE wta, AFAIK, and have experienced, 72-96 dually wheels should fit your truck, 16" steel rims should be fairly easy to find on craigslist or the like.

 

DRW: Some of the following are 16" x 6" .. some are 16.5" x 6" / 1967/97 F350; 1969/74 E300; 1975/2014 E250/350.

Sterling 10.25" rear axle introduced in 1985 F250/350. Same 8 lug 6.50" bolt circle, but the Sterling hub is larger in diameter than the Dana 60/70.

F250's were not available with DRW

Note: Ford measures wheels across the inside flanges, not across the outer lips.

 

Thanks for that information. If the wheels from '85 and up have bigger hub bores, they would work if they are lug centric. That's a question I meant to ask in my first posting. Are all these Ford dually setups hub or lug centric, or are some one and some the other depending on model year? Thanks again.

 

Look for E250/350 (Econolines), they didn't have Sterling rear axles.

 

Any particular year Econoline? Thanks. You've been very helpful.

 

1975/2014.

People walk past Econolines in wrecking yards, not knowing that some of the parts are the same as F100/350 and some Bronco's.

Your '77 F350 has an instrument cluster back made of a composition material that can TURN TO DUST before your very eyes!

1981: Ford came out with hard plastic cluster backs for Econolines, these were also the FoMoCo replacements for the POS cluster backs.

1981/91 Econoline with oil/amp gauges is the retrofit for: 1975/79 F100/350; 1975/80 Econoline; 1978/79 Bronco.

1971/77 F100/350, 1974/77 Bronco; 1975/77 Econoline use the same steering wheel and horn pads...except 1975/77 F100/350 & Econoline w/speed control.

 

They are lug Centric.

 

Thanks for that information. It seems to me that later model '85 and up 16 inch wheels will work since the lug nuts locate the wheels.

 

FWIW :

If you have the flange type lug nuts, they do not centre (locate) the rims.

This picture shows a flange nut resting against a stud.

Look at the rotor, where the studs exit the rotor, and you'll see a counter sunk section.

At the bottom of the picture, inside of the lower left stud, the pin is used to line up the rims.




This next picture shows that the eight fitting holes have alternating concave + convex lips, and 4 of the lips centre the rims against the counter sinks in the rotor.

The flat hole aligns with the pin.



The bolt pattern you need is 8 x 6.5'', a.k.a. 8 x 165.10mm.

Check your existing back space measurements so that you can ensure the 16'' replacements are the same, or an acceptable similar.
