Tubes Vs Tire Stems

Picked up some good used Goodyear Wrangler Radials for my '57 CJ5 for little $. I'm going to put them on the OE 15" steel wheels. My question is: will I have to use tubes on these wheels, or can I put TR-413 valve stems on them?

 

My 1966 CJ5A has 235/75R15 with no tubes on steel wheels. They are fine for my use.

 

If the wheels are in good shape you should be able to run tubeless tires. I have a set of KH wheels in the barn that came off a 50 Willys pickup and these have tubeless tires.

 

I had the same concern when I restored my ' Circa 1962 ' K-H wheels . I mounted 235/75R16 's ( tubeless) without any trouble so far.

 

Awesome. Thanks to all for the input! I'll just get some new valve stems - saves a bit of cash there too!

 

By the early 60’s, factory rims have raised “safety beads” to help hold the tire bead in place on the rim. This coincides with “tubeless” tires becoming popular. Yes, you can run the early rims with tubeless tires, but you take a chance of rolling them off the beads at lower pressures.
Besides the cost of tubes (radial tubes), the disadvantage of running tubes is getting rust inside around the stem hole.

Thx Donny. I'm going to mount them tubeless this week. I'll keep them at @44 psi.

 

I run my tires about half that.
44 PSI is gonna ride like a Mack truck...

 

Agreed, I run about 20psi on the street in the old Jeeps. They are just too light with too stiff of suspension to run 44psi.

 

Kesey Hayes tubeless rims start being used by Jeep in 1963

 

Same.

 

How do you tell the difference if they are tubeless rims? I'm running the 15x4.5 wheels that came on my 62 without tubes

 

FYI ….a typical wheel is composed of two main parts; the rim and the disk.

For one thing note that All 4.5” wide x 15” or 16” Jeep KH wheels are tubeless design.
Also tube design wheels will have a raise ring ( bump) going around the rim.
1962 CJ’s would still be standard with 4.5” x 16” and 4.5” x 15” was one of the options for that year.
The other option in 1962 was heavy duty 6” x 16” .
And no tubeless CJ wheels were available till mid 1963 when tubeless 15” became the revised service standard.
This info is gleaned from reading the service standards of that era and observing unmolested CJ’s from that same era.
