I think of a split rim as more a wooden wheel thing (and perhaps some trucks) - the rim actually is not a continuous ring and you have to use a rim spreading tool (a sot of three point jack like tool) to get the rim over the wheel assembly - also more fun than a barrel full of monkeys.


I just did 10 Auburn 852 wheels over the past month - My broken record phrase has been "do not chip my paint".

Thanks, that sounds like good advice. I'll go with the nickel 90 degree stems.

At the garage where I worked in high school, sometimes we got wheels like this and they always called them split rims. So I learned something new, thanks.

When I did the 1932 Packard Twin Six with the 7:50 x 18 Bedford Double White Walls, the 90 degree nickel plated metal stems came via Lucas Tire (via Universal Tire in Pennsylvania). I have not called Lucas in a while, though I usually ask for "Maytag" and he does a fine job in helping.

You will need flaps as well - wire wheel spokes and tubes do not get along.

And you will need to use talcum powder (just plain Jane old fashioned Johnsons baby powder works great) on the tubes, flaps, and casings - just a super light dusting. The talc keeps everything from sticking together and allows some flex movement. A lot of people will tell you this is not needed, but having put well over 100,000 miles driving prewar-cars I have never had a bias ply tire/tube let me down on the road. My tire guy (who also has 1930's cars) just retired on Wednesday of this week after 60 years as a Goodyear dealer - he swears by talc.

I usually lay the hub of the wheel up on some lumber, put on gym shoes, and and "walk" the lock ring in (tuck one end in and then step on the ring and walk around it) - I have had good success with both chrome and painted wheels.

Also, I have become paranoid about code stickers in tires - always double check as stickers also do not get along with tubes.

And, inflate in a cage at a store that does truck rims. It is not an old wives tale - lock rings really can kill and maim people.

I always heard them referred to as snap rings and learned early that the safest way to air up a tire with these devices is to make sure you are off to one side when doing it. If the tire and wheel are off the vehicle,turn the wheel and tire fACE SIDE DOWN.

For a definition of lock ring rims and split rims go to Universal tires web site. The term does seem to be used interchangeably but the two rims are not the same. Not even close.

The largest tubes available in Germany I found are 7.00-19, like these:

But it might be useful to ask this shop for other sizes, possibly not listed in their Onlineshop.

Good luck.

@mike- most people that I know use the two terms interchangeably. You have to remove the lock(ing) ring to "split" the tire/wheel assembly apart to perform a repair. <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->

Don't you mean they have lock rings? I didn't think Duesenberg had split rims. But what do I know.

Thanks for all the help. These are split rims, so no chance of going tubeless. But they are easy for a do it yourselfer to mount, I just have to put chains around it for safety while I inflate it.

I have bought tubes from "farm" tire stores and universal tire in PA. Just put one of universal's on a Stevens Duryea but have not driven it yet. The Michelin's are not available in many sizes and are very expensive and very thick. If I have any tires with tubes I can't mount myself they go to the "farm tire store". They no how to mount tube tires and most "regular" tire stores don't.

Being able to FIND these odd sizes is a minor miracle today.Back in the days when these cars were sold for $600 or less,7:50x19 tires were extinct which explains the 7:50x17 wheels on cars that had the 19's when new.
You might check European sources.I saw a Murphy CC at Auburn a few years ago that had Michelin 7:50x19's,six of them.
If Matt in Germany sees this,maybe he can source out something not made in China.

Hello Joel and Bob,

I haven't bought a new innertube in the last 6 or 7 years, but it looks like there are some similar tube-problems in Germany aswell. China-junk is everywhere!!! <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt=":?" title="Confused" /><!-- s:? -->

The problem would be the (today often used) "artificial rubber" material (Butyl-Rubber or IIR). So I can't give any recomendations. Maybe Andreas (61xlch) has more experience with todays tube and is able to recomment a brand.

Farm-machines/-tractors often use innertubes in its tires, so if there is a farm-machine dealership/shop in your area, you could ask there for a good quality tube. I am pretty sure they know good quality. No dealer can allow himself to sell junkstuff (a second time) to a farmer when he wants to stay in business with the farmer <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: --> <!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) -->

In question of "valve-style", I guess that an "elbow-valve" faces more centrifugal force (on a fast spinning wheel) than a "straight" valve -> more friction btw. rim and tube?! -> higher danger of damaging the tube?


Cheers

Matt

Is it possible to seal the spoke from the inside of the rim? I thought that one of the vintage wheel manufactures can do this. Then no tube needed. The valve stem might be a problem if the hole size is not up to any current valve specs. Just a thought. <!-- s:idea: --><img src="{SMILIES_PATH}/icon_idea.gif" alt=":idea:" title="Idea" /><!-- s:idea: -->

I have been told there are no tubes made in the US any more.

I decided to get a new set of Firestone 7.50-19 tires for my 1929 Duesenberg, now I need to pick out the proper inner tubes. The last time I had a flat due to a puncture, I decided to buy a new tube, rather than patch the old one. Well the tube I got was a chineese piece of junk, it felt like recycled bubble gum, like the rubber was not properly vulcanized. It lasted about a month and then went flat, so I patched the old tube and put it back in and it has held air for 4 years.

So I don't want to make the same mistake of getting junk tubes. Who sells high quality innertubes these days, and does anyone recommend a specific brand?

Also, what style of valve stem is recommended for an authentic look? Brass? Nickel? Rubber? My spokes are chrome. I think it should have an elbow on it so the open end protrudes out through the spokes for easy access. I have seen pictures on line where some stems have a 90 degree angle, and some have more of a 45 degree angle. Which is appropriate?
All input is appreciated!
