SAFETY QUESTION--Changing a model t tire

I have a couple of bad tires on a 24-25 model t coupe. I have a couple of model a tires that are the same size. The wheels are wood on the t. Can I just unbolt the metal ring and pull the tire off. Is the metal ring a spring like on split rims?

My safety is my concern and I will appreciate all tips.

Thanks
 
Many 1925 model T's have 21" tires. It was the first year that they were available on the T's. 1928 and 1929 model A's use the same size.
 
You should use a "Rim spreader" - a 3 legged screw jack sort of thing that is mainly used to spread the rim back into the tire when re-assembling the rim. Most of them also have hooks on the 3 legs that allow you to pull the rim into a smaller diameter to remove the tire. There is a joint in the rim with a locking device to hold it together once in its operating position.

To remove the tire, remove the rim from the wheel, let out all of the air, undo the locking device, place one leg of the spreader near the joint - on the side that should be obviously meant to slip inside the other side, pull the rim small enough to remove the tire - no more.

Reassemble in reverse order, a flap is a good idea as the joint is very apt to pinch the tube on assembly & is a point that wears the tube in use. It sometimes is a good idea to lightly inflate thr tire then ,mount the rim on the wheel before bringing it up to full pressure - (35 psi).

A bent rim is not uncommon & can be very frustrating. You can change these tires without a rim spreader but it usualy involves tire irons, bars, screw drivers, extra patches & band-aids. Impressionable young children should not be exposed to the process!

Thanks for the information. Will model A tires work or do I have to by cincher type tires that were mentioned in one of the posts above?

The earlier Ts used clincher tires in 30 x 3 or 30 x 3 1/2 size. The rims for these are not split rims. The later cars came with 21" tires. There was an overlap where some models came with either type as an option. If you have split rims they are 21" tires which were used on 25 through 29 Ford cars and many other makes as well. The size will be on the sidewall of your tires - what does it say?

They say 4.40-4.50-21. some are Firestones and some are Armstrongs. I was going to take some pictures but my camera must need a new battery. The lens stays popped out and will not retract. It has been on the charger for a few days. When I go vote I will see if they have a battery that will work.

My friends say there was a waiting line to vote at 8:00 am

I sure appreciate your responses.

Thanks
 
If you have 21 inch tires and 21 inch T rims thay are NOT clincher type. The "A" tires will fit BUT you NEED the wide heavy protective RIM FLAPS and inner tubes with valve stems long enough to fit through the wood wheel fellow. Coker Tire will have both WIDE Flaps and inner tubes. :)
