Oregon Desert model 45 Posted August 27, 2022 Share Posted August 27, 2022 Rims are freshly primed. I managed to get the tire onto the rim up to Fig. 8 in the "Changing Tire" procedure using a tire iron only once. Then it gets real difficult unless a lot of paint is sacrificed by a lot of metal on metal prying with the tire iron. Fig. 8 shows a jack handle or speedwrench prying against the overlapping locking tab which isn't really that strong. It took a lot of force with the tire iron to get the rim end to make this jump. Then I could not get the ends that final 1/4" until a hydraulic jack was placed inside the rim. The final damage was when the "handle" of the locking tab bent out as I was trying to close the lock. A lot of primer got scraped off getting this tire on. Any tips for tire installing without losing so much paint ? Do those rim spreaders with a hand crank make this go any easier ?

JFranklin Posted August 27, 2022 Share Posted August 27, 2022 (edited) That is what a paint brush is for. The 3 leg rim spreader is a handy tool. Edited August 27, 2022 by JFranklin (see edit history) 2 Link to comment Share on other sites More sharing options...
Layden B Posted August 27, 2022 Share Posted August 27, 2022 Note that the 3 legged hand crank spreaders were made and sold by non-rim companies! Such items can easily bend a rim and make more problems than they relieve. No rim manufacturer recommended them. A bent rim is VERY tough to straighten( semantics for make round again)! Try putting a plastic garbage bag between surfaces that would rub together and over your tire iron. Lubricate the tire with a bit dishwashing soap in water. 1 Link to comment Share on other sites More sharing options...

I have a couple of rim spreaders and you know where I live. I think I have one to sell too! Also, I use aluminum rattle can paint that is easy to touch-up.

DonMicheletti Posted August 28, 2022 Share Posted August 28, 2022 Lots of talcum powder as a lubricant helps too. I have always had good luck with my 3 leg rim spreader 1 Link to comment Share on other sites More sharing options...
dibarlaw Posted August 28, 2022 Share Posted August 28, 2022 (edited) Kevin: Be carefull out there! From my own experience on the changing of the 600X22 spare on my 1925-45. MOST IMPORTANT! The photo diagram steps work well on newer fresh flexible tires. The replacement (what I felt as a flexible tire) a probably pre-WWII U.S. Peerless was a fight. Using the rim spreader/tire irons etc. corn startch RUGLIDE etc. I could not get the last section to drop over so the rim was parallel all around. Fig. 8 and 9. I had a 5' digging bar to help as I leaned into it I heard a loud "POP". The sound had nothing to do with the rim or tire, It was my right shoulder rotator cuff. The pain was undecribable! I was out of commision for over 6 weeks. Edited August 28, 2022 by dibarlaw spelling (see edit history) Link to comment Share on other sites More sharing options...
Oregon Desert model 45 Posted August 28, 2022 Author Share Posted August 28, 2022 That tire is only about 37 years old, so not quite petrified like some I have encountered on old wheels. I smeared liquid dishwashing soap around the tire which made it somewhat easier than the tire I installed on the other rim, which lost even more paint to the tire iron. That primer is not the most friendly for touch up since it is epoxy primer with 4:1 mix ratio. I was hesitant to put the jack in there, but neither tire iron or big screwdriver were effective in spreading it that last 1/4" to get the pin lined up to the hole in the overlapping tab.

Terry Wiegand Posted August 28, 2022 Share Posted August 28, 2022 The hydraulic jack setup in the one photo is a very viable way to get things done. I have gone that route a couple of times and it works. As was mentioned, a person has to be careful so as not to bend a rim. The other point is the condition of the tire. Mounting split rims into new tires is a piece of cake compared to working with 50+ years old, hardened rubber tires. I have used corn starch on the tubes and tires proper to help things move and/or slide a bit and I am here to say that this approach works and works really well. I personally cannot speak about mounting painted split rims. I do know a bit about working with Cad plated rims.

JFranklin Posted August 28, 2022 Share Posted August 28, 2022 Back when your car was new, and horseshoe nails were strewn over miles of road, people didn't worry at all about a few rim scratches, so touch-up isn't a sin. P.S. My teachers always got on me for run-on sentences! 1 Link to comment Share on other sites More sharing options...
dibarlaw Posted August 28, 2022 Share Posted August 28, 2022 I was finally able to get the rim closed. I did have these rims powlder coated but are now scratched up from the fight. 1 Link to comment Share on other sites More sharing options...

Larry Schramm Posted August 29, 2022 Share Posted August 29, 2022 Here is what I use to change those types of tires. 5 Link to comment Share on other sites More sharing options...
Morgan Wright Posted August 30, 2022 Share Posted August 30, 2022 I notice you used the tubes with the rubber valve stem. Big no no. You should always go with the brass valve stem with the nut that tightens on it. With the rubber one, the tube can slip relative to the rim and the rim will sever that valve stem right off giving you a flat tire. Ask me how I know.

Larry Schramm Posted August 30, 2022 Share Posted August 30, 2022 Rubber valve stems are fine to use as long as you keep enough pressure in the tires, especially the rear tires. 2 Link to comment Share on other sites More sharing options...

If you keep a minimum of 50# in your tires you will not shear the stems. However, longer metal stems are typically needed for wheels with wood fellows.

Morgan Wright Posted August 30, 2022 Share Posted August 30, 2022 (edited) These tires are 95 years old. 2 are Miller Tire Company (went out of business 1925) and 2 are Cooper. The correct valve stems are metal like these. Edited August 30, 2022 by Morgan Wright (see edit history) Link to comment Share on other sites More sharing options...
michealbernal Posted August 31, 2022 Share Posted August 31, 2022 I have always had good luck with the hydraulic jack method provided you don't get crazy and apply too much pressure and deform the rim. Work slowly and watch what is happening. Use just enough pressure to almost get the ends aligned and then use a large screwdrive for the final alignment. I used a very small pin striping type paint brush to deal with the minor scratches. Good luck. Link to comment Share on other sites More sharing options...
Jim Mead Posted September 2, 2022 Share Posted September 2, 2022 Maybe not for the final expansion of a split rim, but for prying tires, especially clinchers, onto rims, wooden “irons” work great. Saw the idea years ago in Tom Reese’ “Brass Tacks” column in AA. Make them from the top 16” or so of a broken pool cue. Platypus the end on your belt sander. Tire moves, paint stays……. Local pool hall had a 55 gal drum half full of broken cues…… 1 Link to comment Share on other sites More sharing options...
Brian_Heil Posted September 2, 2022 Share Posted September 2, 2022 Tape. Lots of tape. Not to protect the rim, but to mask the tire and stem when you repaint the assembled unit. 😝😝😝 1 Link to comment Share on other sites More sharing options...

Hubert_25-25 Posted September 6, 2022 Share Posted September 6, 2022 This shows the advantages of the rim spreader. It is used differently for removing a tire and then flipped for installation. I find it very difficult to change a tire without one. Hugh 5 1 Link to comment Share on other sites More sharing options...
Layden B Posted September 6, 2022 Share Posted September 6, 2022 You will never bend and ruin a rim with this method. 2 Link to comment Share on other sites More sharing options...
