my 24 t had 21" split rims on it when I bought it. I would like to put the original size tires back on it but don't know if I can just get rims and tires ? here are a few pictures of what I have. thanks. ken
You should be able to swap someone as the 21 inch wheels are very desirable. You might want to reconsider: 30 x 3-1/2 tires are quite expensive, made in Vietnam and last about 7000 miles. 21 inch tires are a little less expensive, made in USA and last nearly forever.
If it were mine, I would stay with the 21 inch wheels.
I'm sorry to say, no you cannot just purchase the 30 x 3 1/2 demountable clincher rims and mount them to the standard Ford 21 inch balloon wheels. The later wheels are smaller in diameter.
Good news, 99.9% of the folks will never know that you have the later 1925 wheels on your 1924 car. In fact those that know that sort of detail will probably think you have a 1925 car when they first look at it (and you don't have to tell them that it is a 1924.)
Additionally the 21 inch tires tend to cost less, last longer, and give you a better ride.
But if you want to go back to the clinchers, I would recommend the demountable ones -- as a flat in the rain at night with non-demountable rims is no fun. You could probably find someone who is willing to swap their set for yours plus or minus cash etc. for which one is better etc. Note Model T Haven has a set of both types see: http://modelthaven.com/pdw.html but I do not know what type of wood was used when they were respoked.

If you want clinchers, demountable or not, you'll need different wheels. They're a couple of inches bigger than the wheels for split rims.
Thanks for all the help guys! I think i'll keep it simple and a better ride. 21" it is. Ken
21 inch tires are still about 30 inches in diameter, they just have taller side walls. About the time the 21's came out they went from measuring the outside diameter of the tire to using the rim diameter.
If you're getting 7000 miles out of new clincher tires you're either doing it in parades or on a trailer. Mine last more like 3500 and are mostly bald at this time. (Wards R'sides)
I run Universal T drivers and the 7000 miles is an about number. The main problem I have with them is flat spots, or, uneven wear.
can my 24 t spare tire carrier be modified to hang the 21" rims on? thanks. Ken
I finally have worn out the Goodyear 30 X 3 1/2 tires on the rear of my '15. I think they have about 15,000 miles! Wish they still were available. This picture is from 3 years ago, they are bald now.
This may be a dumb question, but are hubs interchangable? I currently have 30x3.5 non-demountable's on the front of my '16 Touring and would like to put correct 30x3's on someday. I thought I could just reuse my current hubs, find a decent pair of rims and have Stutzman work his magic.
Yes, but if your T is an Canadian build, it would have the right wheels on it, being 30x3.5
A little thread drift -- but at least it is Model T and wheels related:
Also if your car is a USA and not an ambulance then you may want to consider making sure you have the correct style hub for the 1915 cars. Any 1906-1927 hub will work for a wheel rebuild but the hub flanges changed from 5 to 5 1/2 to 6 inches and the design of the hub also changed.
See: http://www.mtfca.com/encyclo/U-Z.htm#fwhubs for the major changes.
See: http://www.mtfca.com/discus/messages/80257/88181.html?1239905425 for a discussion and some good photos of the type of hubs that originally would have come on your 1915. Note -- lots of folks do not care as long as it fits and functions and that is fine also.
++++++++++++Back to the original thread:++++++
Ken after deciding to keep the balloon tires on his car asked, "can my 24 t spare tire carrier be modified to hang the 21" rims on? thanks. Ken"
The short answer -- anything can be modified -- but it would probably be easier to swap for one that was originally designed for the balloon tires.
From the thread at: http://www.mtfca.com/discus/messages/80257/99271.html DaGunny posted the 30 x 3 1/2 and the 21 inch balloon spare carriers next to one another. The 30 x 3 1/2 is larger because the 30 x 3 1/2 rim is larger on the inside than the 21 inch balloon tire.
The spare tire carriers are bolted to the car so you do not have to do any riveting etc. to install them. You could also probably use the later 1926-27 style “Y” bracket shown in the thread at: http://www.mtfca.com/discus/messages/80257/97650.html Can someone verify that the 1926-27 “Y” bracket spare tire carrier for the TOURING would bolt on (not original – but does it function fine). I would guess but I do NOT know that it would function fine on the touring but the 1926-27 Runabout spare tire carrier would not function fine on the runabout without additional bracing. In the price list of parts they are only listed for 1926-27 use for both styles. Note for 1926 the Touring, Tudor, and Fordor used the same one and the Coupes and Runabouts used the same one – and of course based on tire size and type of wheel they would have the 30 x 3 ½ “Y” or the 21 inch size “Y” or no “Y” at all if they had wire wheels.
You might contact Smith & Jones Antique auto parts in Columbia SC. When I was over there Sat in addition to great ice-cream they also had a rusty spare tire carrier sitting on the shelf. I do not know if it was the clincher or balloon style but it was a 1925 or earlier style. Also Mark at Model T Haven might have one.
Good luck with you car.

I got one of each that I am taking to Hershey. Dan
I'll be at Hershey Dan and thank you Hap for your help. I really don't want to cut my nice original carrier even if I can't use it. someone else might need it someday. thanks. Ken
Hay Dan! where will you be located at Hershey? Ken
