I wanted to take the time to share some of my findings on dually rims. My stock rims were totally shot, if you have simulators wash behind them often! My goals were to get 265-75-16” tires mounted on rims of the proper width and of the proper offset to allow normal loads. I also didn't want the tires to stick out beyond the fender flares so spacers were out.

A stock CTD has enough space in the rear fender well to make this happen. Factory wheel offsets for dually rims are usually 5", the truck that came with 215-75-16 stock tires had these rims. When the trucks went to a 235-75-16 tire the offsets were widened, I couldn't get a good measurement off of my rims but the offset is greater then 5" (I still have tires on my rims.) Hayes Lemmerz makes aftermarket replacement wheels with a 5.350" offset, its coined fitting our trucks and early fords p/n 129383. This is the widest offset rim you will find. I checked with Hayes, Accuride, Ford, Brentz & GM. I ended buying these and they are being powder coated as I type.

In order to fit a 265-75-16" tire on one of our trucks and maintain all tire clearances a special rim is needed. You would need a 16"x7" rim with a 6" offset. I found one place that could make these B&W Wheel in California, $300 each. Stockton wheels could modify my wheels for $150 each. This offset will keep the wheels in the fender wells and provide enough clearance between the duals. This deep offset would create issues on the front running into the steering arm on the knuckle with the tire. The steering knuckle issue would be solved by a jump to 2003 and newer 17" wheels but this brings up a whole new issue. The difference between hub centric, lug centric and stud centric rims. The 17" wheels use 5.350" offset and a 235-80-17 stock tire. I found that this isn't a very popular tire size.

Our trucks are considered stud centric with the coined rims providing the centering for the inner dual. Modern trucks are hub centric using flat faced rims, Dodge uses a 4.770 hub diameter, Ford 4.880", and Chevy is smaller. Our 1st gens have a 4.750" hub diameter. .020" isn't much and it may have worked but you still can't positively center the inside dual. Because of our 5/8"-18 studs the only lugs nuts with a floating washer available are from Alcoa, you could go to the 9/16" studs and stock lugs but why change both? So with the centering issue, the lug issue, the narrow 6" rim width, and limited tire selection I decided to pass on the factory 17" option.

This leads me to look into 19.5” rims, they solve the steering clearance issues, have long tread life, but VERY limited tire selection and are VERY expensive. To move to a 19.5” you would need rims from Rickson truck, or American force which are made over seas. For a 19.5”x6.75”x5.75” offset rim and a 265-75-19.5" off road traction tire your cost will be $550 per wheel plus balancing, plus lugs, trim rings and center caps. As I didn’t have $4K to spend on them I quit that option.

So we are back to considering how to put them on factory style rims which is just not possible without rubbing or spacers. One tidbit I picked up from the tire rack, every tires dimensions are listed with a measuring rim, the over all width for a rims (buldge to buldge) adjusts by .200” for every ½” of measuring width change. For example you have 10” tire measured on an 8” rim, and your rims are 7” wide the tires width would be 9.6”

So after all that I am back to putting a new set of 235-85-16” tires on. I have ordered a complete set of Firestone Destination M/T which will be here by the weekend. Hopefully all goes well with the rim powder coating and chrome plating of my stock lug nuts.

 

Acuride doesn't make the rims for Rickson, as they do no such "coining".

I bought my new hayes rims p/n 129383 from Southwest, $74 each and $82 shipping to Michigan. The rims are at the local powdercoater getting coated with Cardinal T064-GR05 semi gloss hammertone gray which matches one of the stock colors buckstop bumper uses. The money I saved by not going the 19.5'" route I am using to get some buckstop bumpers front and rear.

No less schwabs in my area that I know of. Are the online? ALso looking for a mud terrian tire because of my trucks intended use. The M55 are great tire, but I have read some absolutely oustanding reviews of the destination M/T's

ruquik--
I was told by Brent from Brents Wheels that both he and Rickson get steel wheels from Accuride. Maybe in Ricksons case the are just getting rim cores or something.

 

Please enlighten me on the 98 coined Ford wheels, as I haven't seen a coined wheel on a Ford since 1979, the last year that Ford used them.

1980, and newer, all have hub-centric, flat-surface wheels, and use flat-cup washer-style nuts.

Also, with the advent of the Super Duty body style, Ford changed the bolt-pattern to some stupid metric dimension that is Ford specific, and will no longer interchange with Dodge and Chevy.

Prior to 1979, there was no difference between Ford and Dodge wheels; lay them side by side and they were identical.

Thanks.

Sorry, I must misunderstood . You can get just about what you need from them, though.

Southwest salesman said they were coined Ford wheels for a 98, maybe not ?
I might be correct to call them bud wheels as there is one hole tappered in and one tappered out, every other hole.
The truck had a vibration, read wheel hop, at 42 mph, no matter what gear. I bought the wheels and put a set of Ultra's on, after cutting the dowel pin, no more bounce.. I spent a lot of time and money chasin' this bounce before I caught it.

Can't see where I said there were 1998 Ford Coined wheels. From the hayes application chart it says ford stopped using coined rims in 1984. Sorry if I was unclear.

From 85-98 ford used a hub centric flat faced rim 4.880 ID. After that the went to the metric bolt pattern.
