carmover Posted August 3, 2018 Share Posted August 3, 2018 What is the tire pressure supposed to be on the 34" tires.The owners manual doesn't mention any pressures. Link to comment Share on other sites More sharing options...
Terry Wiegand Posted August 3, 2018 Share Posted August 3, 2018 Ronnie, My 1922 Model 48 has 35 X 5 tires (that is a 25 inch wheel) and I run 70 pounds in them. I am not real sure when the switch from the high pressure to balloon tires took place. Terry Wiegand Out Doo Dah Way 1 Link to comment Share on other sites More sharing options...
MCHinson Posted August 4, 2018 Share Posted August 4, 2018 I don't know the answer but I have a local friend who has a 1923 Buick. His car has 33 x 4 1/2 inch tires on it. We were talking about his tires today. He was upset because he was looking for a set of whitewall tires to replace the ancient tires on his car and could not find any in that size. Can anyone tell me if there are other size tires that would fit on the existing wheels? 1 Link to comment Share on other sites More sharing options...
Grimy Posted August 4, 2018 Share Posted August 4, 2018 I bought a set of BFG blackwall 33 x 4-1/2 tires for my Paige from Coker about 10 years ago, and I recall that whitewalls were available in the same size THEN. In contrast to Terry's recommendation which is consistent with pressures recommended when these cars were new, I have 35 x 5 tires on my 1918 Pierce and run the rears at 55-60, fronts at 48-52, as recommended by the full-time wrench for a large collection of brass vehicles, and get better steering and ride than at the higher pressures that were common decades ago. Variables MAY be our better roads, and better tire construction. Suggest experimenting with different pressures for your application. On the other hand, I run balloon tires on my 1925 and 1930s cars at 40-42, higher than generally recommended. 1 Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted August 4, 2018 Share Posted August 4, 2018 (edited) 1925 is the first year for Baloon tires on Buicks. These are 32 PSI recommended for the touring car. The 1922 Dodge I have been using takes 50 PSI in the tires. That's a lot of work with a hand pump with leather seals on the side of the road. They also made the 22" tire for this 1 year only. 21" rims in 1926. Edited August 4, 2018 by Hubert_25-25 (see edit history) 1 Link to comment Share on other sites More sharing options...

Most tire companies have stopped making whitewalls for the newer cars, I hope Koker will keep making them for classic cars! Link to comment Share on other sites More sharing options...
carmover Posted August 4, 2018 Author Share Posted August 4, 2018 My 23 Model 50 sedan has 34x41/2 made by the Lincoln tire co. and has no mention of tire pressure on them. My 25 model 6 25A enclosed touring runs 600x22 and has the recommended pressure on them at 36 psi. Link to comment Share on other sites More sharing options...
Terry Wiegand Posted August 4, 2018 Share Posted August 4, 2018 George, I bought these B F Goodrich Silvertown Cord tires that are on the car in 2002 from that famous tire dealer down in Chattanooga, Tennessee. The reason that I run 70 pounds of pressure is because it is molded onto the sidewall of the tire(s) to inflate to that pressure. I can honestly say that the car drives and handles OK with pressure at 70 pounds. This Buick is a heavy automobile also.

Terry Wiegand Posted August 4, 2018 Share Posted August 4, 2018 All, A couple of things that I will add are - the tires are White Walls. They sure look nice against that Cobalt Blue body. The other thing is that the 35 X 5 tire is an oversize of the 34 X 4 1/2. This car and my 1920 K-46 both have 25-inch wheels. The first time that I drove the car with the new tires, it almost felt like it had power steering as opposed to the skinny tires that were on it when we bought the car. That is the car and tires in my avatar. Here is a photo of the car with the BIG tires. Terry Wiegand South Hutchinson, Kansas 1 Link to comment Share on other sites More sharing options...

I just checked the Koker Tire website and they list a Goodrich Silvertown Bias Ply whitewall in sizes 32x4,34x5,33x4,36x4,and36x41/2.They are high pressure non clencher style in stock. 1 Link to comment Share on other sites More sharing options...
Grimy Posted August 4, 2018 Share Posted August 4, 2018 Looks great, Terry! I prefer blackwalls on most cars thru 1924 or so, but your car looks terrific with them. My Pierce is on the heavy side, too, so I experimented with pressures and decided to stay with less pressure. Whatever works for each car... 2 1 Link to comment Share on other sites More sharing options...
Morgan Wright Posted August 4, 2018 Share Posted August 4, 2018 You can put balloon tires on earlier rims. Literature from the 1920's shows tire companies advertisements, they were getting people with old skinny hard tires to upgrade to balloon tires on their older cars, without changing the wheels or rims. Coker isn't hip to this. 1 Link to comment Share on other sites More sharing options...
Brian_Heil Posted August 4, 2018 Share Posted August 4, 2018 Been running 24 x 5.00 BF Goodrich balloons on my ‘23 for years. Much better wear and stopping contact area. 36 psi on the sidewall. I run them at 40. From Coker. Watch the manufacture date / age on anything you buy from Coker. Twice I’ve had to return tires that came to me 7 years old already. 3 Link to comment Share on other sites More sharing options...
Mark Shaw Posted August 4, 2018 Share Posted August 4, 2018 (edited) Just a quick note: Always run a minimum of 60 psi for clincher wheels & tires.... The higher pressure is the only thing that keeps the rear wheels from shearing the valve stems. This is especially true for vehicles with a grabby clutch! Lower pressure on the front is OK and may afford better handling and more comfortable ride.
