I tried to put my 21" new Tires on my old
21" Split Rim for my 1925-6 Model T Pick up
and the tires went back on the rims while collapsed, but when I try to Open them back to lock position the Dont expand enough to lock back in place.
Do I need a special Tool to get the Rim to expand back to the original Locking Position,,
Or Do I have a 21" tire trying togo on a 22" Rim?
Is that Possible..
Not having a spreader, I used a scissors jack to open the rim enough to lock it back in place. Worked great.
Dave - I'm not too good at using "keywords" in this forum to research past postings, however, some time ago, this subject came up (mounting tires on split rims) and I recall that one forum member discussed (and posted photos) of a method he used, perhaps similar to what "Ron in Central Massachusetts) mentioned.
What this "method" consisted of was a couple of "half-moon shaped pieces of wood, cut out of a piece of 2" x !0" or 2" x 12" and placed across from each other inside the rim, and carefully spread apart with some type of small mechanical jack or small hydraulic bottle jack. I actually tried this, and it worked very well. Hope this helps,......harold
See this thread:
Bingo! You found the thread I was talking about! Thanks Mark,.....harold
Dave, I did it almost exactly as "Harold Schwendeman - Sumner, WA" described only nothing so elaborate as "half moon shaped pieces of wood." Lay the rim flat on the floor. Wedge a 2x4 inside the rim opposite the locking mechanism of the rim - this forms a "stage" or platform for the scissors jack. Place the jack on this staging with a small block of wood on top of the jack, aligned with one side of the split or another (not so close to the lock that you cannot close it). Crank the jack up until it pushes the rim in place and you can lock it.
I just put my Model T jacket between the two lugs on either side of the latch. Of course after that I bought a correct rim spreader/collapser.
Seth, that would work too - I just didn't have a small jack that would extend that far.
Whatever you do, don't use too much force or you will bend the rim and make it out of round. Guess how I know this!
I had a similar experience and found that the rim liner being used was cut too wide and too thick and was actually between the tyre and the rim instead of being just on the lower flat section
Seth, did you have some type of expanding tool in your "JACKET" pocket? I tried this but the jacket just lays there. What am I missing? Bob
You can use a small bottle jack to expand the rim BUT as others have stated you can bend the rim if your not careful.
If you have a T that has split rims a rim spreader is a must have tool. I finally bought one to mount the new tires on my 24 Coupe and it works great.
Spend the money and do it right. That's what I did.
You might measure the I/d of your new tires and compare that with the I/d of your old ones. Seems there is a bit of a difference between new and old.
A friend bought a new set and could not get them mounted. When he checked the actual sizes the new tires were nearly 1 inch smaller i/d. He called the manufacturer and they quickly sent him another set. Seems this is an ongoing issue with quality control for overseas manufacturing. As quickly as they took care of the issue I'm thinking it must be a continuous problem.
Make sure that the tube isn't getting pinched between the rim and the tire. Ifn a bit of the tube gets pinched in between you'll never get that rim to latch up.
Nobody else at the auction knew what it was, so I paid $1 for it.
