O.K., I know there's been lots of info on 15 X 6" rims that will fit
over the Turner disc brakes. The NWRA # 40273 that Bob Helm sold and
Ford used for years is no longer available. Same for the older
Chrysler rims that fit. Most RV trailer rims are 5 lug 4 1/2" circle. I have located one that has 3.75" backspace and .5" offset. It will clear the Turner calipers. The original rim has 4.125" backspace. I'm not an engineer and wonder if anyone can advise me of any cons of using the trailer rims. :)

My first question (it may not matter to you if you have a ratrod) would be: will they have the "stop bumps" on each side of the valve stem and the proper rim to accept stock wheelcovers? [?]

It is a given that they will not have the right Stude. pattern bumps on them to accept the bottle caps or slots to accept the pre-1958 clips & caps, so unless they are white spokers or something, it will be impossible to "dress them up". :(

Roy,

Rich is correct regarding the wheel cover "stop-bumps" on either side of the valve stem. That condition can be eliminated very quickly with the addition of a couple of "bumps" made by a mig welder. Measure the correct spacing from an original wheel first. As for the small hub cap retainers, they're "circle" is too small for the OEM Stude caps and too large for Mopar caps. The most concerning factors are the "lateral" and "radial" runnout. "Utility" or "trailer" wheels do not have to meet the automobile standards in those areas, therefore, unless you are able to spin up each wheel to inspect for either/both of these conditions before you purchase, you may very well end up with some wobbly, out-of-round wheels and tires driving down the road.[xx(] Like other parts, once you mount/paint them, they're yours.:( OBTW, close inspection will reveal, if in fact it is a trailer wheel,(by law) it will be stamped somewhere..."this wheel is for trailer use only". One good point, these type of wheels are much stronger than standard passenger car wheels. Standard car wheel, (X40273), is rated at 1400 lb. capacity, while the comparable trailer wheel is rated at 1820 lbs. Having listed the above information, I would visit my local U-Pullit, Pull-a-Part, etc, there you have a chance to spin the wheel on a "free" front hub, and check for the above runnout issues as well as rusted, bent,etc. I know they're cheaper than a new wheel, plus you might get lucky and get some decent tires with them.;) Hope this info helps.:)

In addition to what Dan and Rich said, a 1" wider rim with 3/4" less backspacing means it will be 1 3/4" closer to the outer lip of the fender. This MAY be a clearance problem.

The stock 15" full wheel covers will fit. There are no "stop bumps". The "dog dish" caps would not fit.

Thanks for the good advice. The rims I'm looking at are new but I'll check the runout.

While they might fit you're gonna need to keep an eye on them- those bumps are there to keep the wheel cover from spinning on the rim and gouging your valve stems. Eventually you may have the wheelcover actually pull the stem out of the rim or cut it off. Loosing a stem isn't a good thing. Radial tires will make this condition worse.

I have had the wheelcover "spin" and pull thye valve stem out. I solved that by using a metal valve stem, no more problems!

FWIW, I've learned to weigh any wheels before buying them. Some trailer wheels are heavier than the hubs of hell. Some of the Ford and Mopar cop car wheels also have a very heavy gauge metal. The extra weight of these wheels will be very noticeable when going up from the too-light OEM Stude wheel and skinny tire. Add in the weight of a much larger tire and the ride and impact harshness can be a big disappointment. A 215/70x15 tire on a 6.5"x15 Mopar wheel can be 25% heavier than the OEM. This will affect the ride.

Best advice is to ask around and try to drive another SDC member car with the same wheel and tire setup before putting big bucks into a change.

thnx, jack vines

Thanks to all of you who responded to my questions about 15 X 6 wheels. I have learned that Summit Racing sells a variety of wheels that will fit. Does anyone know from experience what an acceptable offset should be? The ones I have looked at have from +3mm to +6mm with a 3.75" backspace. Other configurations are available but these seem closest to the original. FWIW Summit Racing has a big store in Tallmadge, Ohio which is right on my way to Lancaster.:)

Roy, FWIW, the "Search" function in the upper right corner will produce at least 50 previous threads where this backspacing question has already been covered in great detail and for every wheel width.

Yep. I ended up have a pair of 15 x 7 wheels made for the rear of my '56 with 4 5/8" backspacing, which is PERFECT for the '56 sedan.

Would Any one have a picture of these bumps and a measurement of there spacing? I am fixing my wheel covers once a week at least. And I need to replace my valve stems soon.

use the screw in brass valve stems, even if you weld some bumps onto your rims.

Hi, Edsel,

What tires and rims are you using? From the photo, the tires appear to be oversize. If those are OEM Stude rims and the wider (radial?) tires are causing sufficient rim flexing enough to move your wheel covers, catastrophic fatigue failure is a real possibility.

thnx, jack vines

Summit Racing has a 15 x 6 trailer wheel made by crager that is very nice lookin for 71$ with a 3.5 inch back space The center hole is 3.1 inch so it may work on the Stude. Center caps are also available. jimmijim

WOW, I am glad I looked in to this now. I guess I need to find some better rims Or skinnier tires.

Tires are p235/75r15


Rims I am including a pic of the spare tire. It has an identical rim to the rest.

I know now I have fat tires.
Crap...

What is a good size to be running with these rims?

Any advise for Cokers or other wide whites?

Man I love this board! You guys are the best!

You should be able to use P215X75R15 Tires on those wide Commander Wheels with no problem, and the P205X75R15 will also work depending on the Brand, some may look at bit small on that big Heavy car because the height varies by Brand for whatever reason. The Commander came with Tires two sizes larger than Champions, so they were pretty tall.

I do not think that Studebaker used the wheel cover stop "humps" way back in 1950, you can tell by looking at the back of your Wheel Covers, I don't think you have the punched out stops on each side of your Valve Stem Hole in order to use the wheel stops.

What you do is, use your Channel Lock Pliers to bend the retaining clips out a little on each one.

IMHO, bending the wheel cover clips to increase the tension only postpones the problem. The narrow, light gauge 1950 rims were not designed for the side loads of today's too-large radial tires and today's highway speeds. The real answer is to go back to the original size bias ply tires or go to rims rated for radials. Your life, your car, your money, your decision.

Hey, Thanks!

I am not disagreeing with you by any stretch. I am glad some one had the fortitude to tell me what was going on with my car.

I bought the car with these tire on these rims. I didn't even think about it untill, I started reading about the spinning wheel cover stuff. I am Just glad I found the answer be for there was any problem.

I just noticed this post. You can still get the proper rims. I bought a pair of them last summer from my local FLAPS and they cost me $41 each. If you wanr, I can get you the name and part number(s).

There is no issue with stem cutting and they hold the wheel covers perfectly.

Hey if it gets more business through the door, unusual as a channel as it seems, all the better. Even better, it's free advertising, and its putting a name over the public airwaves with minimal effort. We have Jade Dragon Tattoo up here, and what's odd is nobody except them advertise over the alternative and metal radio stations(and TV), after midnight. But, if it brings them business(considering the time of the advertisement and the people who listen to the station), more power to them :D :D.

Here is my humble Opinion.
RUN from them, just saying.
I dont know for sure.

We dont advertise. We are busy. I dont need to say much more about us. 19 years and running now.
We do what we can do, I cant say anything about anyone else.

If some one would like a tattoo or to chat about a funny tattoo story or Just to B.s. Just call me. I would love to here it.

Duelly noted. Hey if what your doing works, keep doing it ;). I can't say much for them either, except they run it on the radio in the early morning. I have to note though, since I am working on becoming a teacher(they look you up and down with a fine toothed comb up here), I have to stay a choir boy on the matter of getting one, with all due respect.
