erichill Posted December 11, 2023 Share Posted December 11, 2023 I am at wits end trying to mount my 34.5 tires on the demountable rims. For the life of me I cannot get the rims to expand far enough to clamp together with the tires on. I know I should be able to do this and I have mounted tires on Model A's but I must be overlooking something or doing something wrong. Does anyone know a shop in this area that I could see if they would take on the mounting? I live north of Atlanta GA but at this point will drive 100-200 miles to drop off is need be.

The inside diameter of the rim where the tire bead sits is 25" If I am understanding correctly to determine tire 34-25 = 9 dived by 2 gives 4.5 so use 34x4.5 tire? I apologize I wrote it wrong above.

1912Staver Posted December 12, 2023 Share Posted December 12, 2023 Usually tires { and rim widths } from this era are described in fractions rather than decimals. For a 25 inch diameter rim you would have a choice of 32 x 3 1/2 , 33 x 4 , 34 x 4 1/2 , 35 x 5 or 36 x 5 1/2. These days quite a few of these possible sizes will no longer be available and you have to use the closest one you can find. In addition to rim diameter , rims also came in different widths. Your rims are probably stamped with the size of tire they were intended to be used with. Your tires at 34 x 4 1/2 fall into the middle of potential 25 inch rims and should fit most 25 inch rims unless they are unusually wide or narrow. 1 Link to comment Share on other sites More sharing options...
Pete O Posted December 12, 2023 Share Posted December 12, 2023 There are antique tools available on ebay to spread the split rim. You can get them for less than $100.00 Here's one: https://www.ebay.com/itm/225839993003?hash=item34951cd0ab:g:Kp4AAOSw0m9lNzvk&amdata=enc%3AAQAIAAAA4GPJrOrkcjpjzMi%2BsFLv%2BjMBVHUDj67ejTHr0EwN7X7iLV5YN2GzVVzyQ9zlhLGnO2ucolKjGuLEYL6MvQE9xljwm82TAPWfHaw3xoOLNwUfmT%2Bo1QEdaiFNzlW58KeIeLn0fdcILbweGY44%2FvAtCcmCX3JIS%2BrRom%2F3Xzn%2BgOfkMhg5tUpEYbWD5CKGBxrEm0%2BhOFz%2BgDnGQ6ob%2F9L0QZtGyd9z95EbaZvPP0NfyktJw87eA2kRmA8O6s5c0kNNDHEw1wj6HEUOnbbAoGV5xd0ukxmJZvEqnu9s0t1YtWQ7|tkp%3ABFBMnOvu74tj 1 Link to comment Share on other sites More sharing options...

I apologize I wrote it wrong above. Measure the diameter of the tire bead & see if it's close to 25" If not, you may have the wrong size tire. It shouldn't take a whole lot of pressure on the rim spreader to get the ends to go back together. You might post a picture of how you've got the spreader located in the rim, you need to position it so that it pulls the ends of the rim apart.
