In my restoration of the Dalotel I am currently stymied by a lack of wheels and tires that will match the original look and will also fit inside the wings on retraction. The original setup was 400-100-8, which means 16-inch O.D. tire, four inches wide on an eight-inch rim. These were by now-defunct Dunlop France. This tall, narrow setup is important to the look of the Dalotel, and also fits easily into the wing.
I have only one original wheel. I have been unable to find a second wheel, nor suitable tires. The wheel is of cast aluminum and has no markings whatsoever. The closest tire sizes I've found are 4.80 X 4 X 8 by Shin which has marginal weight capacity ( 765 #, but my gross is 1800 #).
The various tires I've found for 5- or 6-inch wheels seem to be too wide. I could make room for a 15- or 16-inch diameter tire that was maybe 5 inches wide, max. I'd hate to have to put in 13.5-inch tires that are 5 inches wide, because the look is just plain incorrect.
Can anyone help here? Have you seen wheels like this one?
Posted: 4/24/2010 12:05:41
Man, don't all shout at once. Well, then, can anyone suggest a suitable NARROW setup with 5-or 6-inch wheels and whatever tires might work?
Any suggestions will be most helpful. Thanks.

Dunlop are still in business elsewhere, have you tried contacting them? Their website has a "tyre finder":
Posted: 4/25/2010 18:02:50
Yes, I did. They were one of the first I contacted. They were essentially zero help, other than informing me the French department was out of business. They suggested one tire that fits a Lear jet, and another that was not much help. I found the AA4AA tire here: http://desser.com/sta_aeroclassic.shtml, which appears to be six inches wide. Also the MCCREARY
500X5-6P AIRHWK TIRE, which is only 13.5 inches in diameter, but also only five inches wide. It may not have sufficient load capacity. Thanks for your suggestion.

I just heard from Dunlop U.K. today with the suggestion of a 16 x 4.4-inch tyre, Dunlop number DR17026T. This tubeless tire apparently fits Mustangs and some Cessnas, and apparently is an "auxiliary:" tyre, i.e., for the tailwheel. It requires a wheel that is very close to what I illustrated above, specifically:
Rim width between flanges: 3.5"
Rim ledge diameter 8.00 (I presume this means 8-inch wheel).
Anyone know the size of tailwheels on Mustangs?

Mustang repo tailwheels are available from Pioneer Aero Service out in Calif. Check their website. I do not know the prices or the dimensions. I hope this helps you. Good luck on your project. ----Tom

If you are looking at 500X5 tires with load capacity, the Sikorsky S76 uses 500X5 16 ply tires at 135 psi. The S76 varients range from 10,500 to11,700lbs GW. I don't recall the tire mfg, but its one of the majors. Good luck.

Azusa makes an 8" wheel, but it is really only for homebuilts. The 8" Tri Star.

I don't know if this wheel from France might be appropriate for you.
It is made by MDO Aircraft in France. I understand that the initial
correspondence with Mr. Bastien is probably best done in French if this
is of interest.

My mistake. The tire I found was for the front wheel of the Cessna Mustang jet, not the P51. Although those tires are available if very much too highly rated for my 1850-pound gross weight, no one has been able to tell me who makes the WHEEL.
Thanks for your kind help

Thanks for your info. Through Christophe Marchand, the test pilot, I have a lead from Beringer in France on a nearly suitable wheel & tire, but it's actually a bit too large in O.D. . What I need is the thinnest wheel and tire that has an outside diameter
of no more than 16 inches. I may have to go with a 600-6, but the OD is
still a bit too large and the thickness is not what I'm after. I'll take a good look at the two you noted here. Do you happen to know the load-carrying capacity of the 8-inch two-piece wheel?
I suspect the OD of the French tire/wheel combo will be on the too-small size. Who would have thought this could be such a knotty problem. As noted in my reply to Mr. Anderson, Cessna has not responded as to what wheels are used on the Citation Mustang, and the tire is way too heavy duty for my airplane.

Those tires are very much too heavy duty for me. My gross weight is 1850 pounds. Thanks just the same.

The wheels are for use on Powered Parachutes, Trikes, and other sport aircraft to 1,000 Lbs gross, so they may not be appropriate.
The best way to check the load capacity might be to verify this with Azusa.
The listing for the wheel and matching hydraulics for homebuilts I am posting below.
It looks like a nice project. It is too bad the original wheels and tires are not available, the plane looks great with them!
Does Beringer have an 8" wheel?
P.S. In searching for the weight of this aircraft online I notice you brought it over from England. I like the idea of what you are doing. I hope you don't mind I am also including a link to the article I found regarding this. I hope when the Dalotel is complete I have an opportunity to see this wonderful project!

I don't mind at all your posting the link to the Epoxyworks article. I'm using West System epoxy for all the gluing, and the Gougeon brothers at West System have been very helpful to me in that regard. Here's another link to a story posted online in Model Airplane News about building a full-scale "model." This tells more of the story, and there are pix below the story:
Thanks again for your help with wheelmakers. Because of illness and an extremly long winter here in Idaho the work is going mighty slowly now. But we persist.

Thanks, Clarke, but bearings are too small and load is not up to snuff. Please know I very much appreciate your efforts.

What size is the axle?
I am searching for a wheel for my own project and am hoping that I also stumble on something for you.

Clarke, the original roller bearings for the axle shaft had I.D.'s of 1.150" and 1.375" or so. Very heavy duty. I will have to rebuild most of the bottom of the gear legs incl. the axles, as there was some damage to one side and I didn't even get all of the other side. But I won't make the axle any smaller than it was.
That latest wheel in the *.pdf file looks mighty nice. I wonder what tyres it takes.
BTW, you could send your email and I'll answer directly if you wish. Or tell me where to find your email if you don't want it posted here.

The Kaspar 26mm axle is close at 1.02 inches. That original axle is certainly heavy duty!
The tire is a 400mm x 100mm -8 15.75" x 3.93" -8
I have emailed you directly.
