6 x 7.25 x 17" Split Rim Replacement/ Modification Choices

Experts, please comment;

Dreaded 6 x 7.25 x 17" Split-Rim...

Option 1: Cut out center, weld in new outer rim > 17" Diameter.
Option 2: Cut out center, weld in new outer rim > 16" Diameter.

Will option 2 be feasible?
As in, has anyone done it & not experienced an issue with the [smaller diameter] wheel interfering with the brake drum?
Preference for 16" = [theoretically] more tire choices.

If a more logical option exists, we would greatly appreciate knowing.

Vehicle Application: 1963 Ford F-350 Napco 4x4

Thank you for your consideration and input.

I’ll begin by assuming your Napco is single rear wheel (SRW). If that is wrong and it is DRW we can have an entirely different conversation.

The first option you list is possible, and is a good option. That option has been discussed in detail several times. The below old thread covers it. The linked thread goes everywhere, so focus on the later postings. Your second option might be possible but the center would have to be cut down to fit a 16” rim.

The better solution is to find a set of Budd 70740 tubeless 19.5s. Described in this below old thread. The 19.5” is the tubeless equal to your tube type 17”. I have a set of four available if you have interest. Stu

Thanks for your reply...

Yes, it is a SRW [Single Rear Wheel], and not a DRW [Dual Rear Wheel]

Why is your opinion that Budd 70740 tubeless 19.5s would be the best alternative, as opposed to cutting/ welding new centers [specifically, 17"]?

Lastly, the shop we have been in contact with is Collins Custom Wheels & Wheelcovers, Bellflower, CA [in business for decades]...

Again, appreciate your advice...

Either is a good option, and might be cost equal if you don’t have shipping to consider using your local shop. The 19.5” is a direct bolt on replacement, and with a radial 8R19.5” tire is the size equal to your 7.50-17” bias plies. The new 17” tubeless rims iirc are slightly wider than the 5.5” original widow maker RH-5° rims which might allow you to go with a wider metric sized 17” truck tire. So that might have some appeal. If you were to go with the 70740s shipping through the Fastenal Company’s 3rd Party Logistics service is cheap, so that is an advantage. Link below. So, either way you can’t get hurt by the widow makers. Stu

Thank you so much...
Indeed there is no consideration for the modified rims...
As well, my brother is keen on keeping them appearing as stock as possible.
But those Budd rims do sound attractive...
You're located where?

Central Illinois. If you want to discuss the 19.5s please do me a private message. Also, before I’ll sell them I’ll need to pull the old dead tires to make sure there is no hidden internal rust that I can’t see from the outside. Stu

So... sometimes the obvious is staring right at you.

As in, it's been over a year since my brother got the truck...
As in, it's been a constant question as to what to do with the rims...
As in, we picked up a rim last night at his house, so we could have the "wheel man" give us his opinion...
As in, when we pulled it out of the back of our truck, at the wheel shop, we noticed...

... that the rim is NOT a split-rim, after all!!!

All four rims are not split-rims...

BUDD D 8 74
68600

Unbelievable...
Two heads are not always better than one...
Especially when neither bothers to really go over something with a fine-tooth comb [or, a good pair of glasses].

Thanks to all, for your input...
Sorry to all, for wasting your time...

... now, on to finding a decent tire - and a spare rim.

No, like so many others before you the absence of an obvious widow maker joint has tricked you into thinking the wheels are one piece. There is a raise band like area around the middle of the rim that is the joint. Below is a photo of the Budd catalog showing the RH-5° rim on the 68600 wheel.



Right below the 68600 you’ll see the 70740 DC (drop center one piece) that was itself an optional wheel on your truck. I have mine at the shop right now pulling the old dead tires. Stu

Edit : here’s a better picture that includes the sizes. Stu

truckdog62563,

You are correct...

We just found out [in the last 10 minutes] about the background of this wheel [68600 / Firestone RH-5]...

... looks like we are headed back to the wheel shop.

So close, yet so far.

TY for the correction.

If I may share some wheel trivia, the 8/74 build date of your wheel tells me that Budd cheated on their promise to the NHTSA and IIHS to stop producing RH-5° equipped wheels in 1972. It’s been known that Kelsey Hayes produced them into 1976, and reported by the IIHS in their Status Reports that are available online. The agreement to cease their production averted a recall effort, but plagues us in the hobby to this day. Stu

I did find it odd to see that date stamp... thinking maybe the Budd # number was in error. But it is not... for a fact, they are a tubeless tire - with the stem emanating from the very center of the rim.

Our quest is not over yet.

Appreciate the trivia...

Update:

Wheels went to shop today...
They will remove the [riveted] centers, & will convert to 7" x 17" wheels.

4 x $125 each

Collins Wheels, Bellflower, CA

Still need a fifth [spare]

Budd 68600 [Firestone Rh-5]

Collins Custom Wheels & Wheelcovers, in Bellflower,CA, did an awesome job on fitting 7" x 17" steel rims on the "Widow-maker" centers. They said they haven't seen these wheels in 30 years...
If you need your wheels customized, these are the guys! Tim & Carlos know their stuff!

My brother opted for a "street tire", rather than an A/T or M/T, as it will be primarily driven on the street - as a daily driver, no less [thankfully, he only has about a five-mile commute...

Those look great, and reasonably priced. The wider rim gives the opportunity to run wider/taller radial tires than would be possible with the OEM tubeless 19.5s. Do you know what amount of offset or backspace your company spec’d in their build so that we can share this with others down the road? Stu

truckdog62563...

I discussed it with Carlos [@ Collins], and with the 7" wide wheel we opted to go with a further 1/2" of Backspacing [to mean, the rim is set back 1/2" closer to the frame of the truck].
In theory, as compared to a 5.5" wide rim, this would make the rim appear only 1" wider on the outside/ face of the wheel.
Further, it would appear that there is plenty more space available, if one were wanting for a wider rim.
My brother wanted to keep it close to stock appearance, and is not considering putting very large [wide] tires on the truck - hence a 7" wide rim.
Collins' work shows up in the product; excellent quality... superior welds.
We hope this information helps others out there...
