Hi everyone - Sorry if this is a repeated thread - but I am in need of help - i have a 1975 FJ40 - and I want to know the factory tire size as I have factory rims.

Also can someone provide me the same factory tire dimensions for my 1964 FJ45 -

I believe both are the same - if someone can confirm that would be great. Also is there a particular brand and thread type to getting it looking as factory as possible?


I show H78 - 15 205 / 75 R15 LT

Thank you in advance everyone!
 
The '75 40 did come with H78-15, generally Dunlop Snow Cruisers. If you are staying with bias ply tires as original, STA makes their Super Traxion in H78-15, L78-15 & 7.00-15. All are very similar in size, all will fit your stock rims fine. The 7.00-15 is made in much larger quantities and so is considerably cheaper than the other two sizes.

The 45 would have come with 15" rims and tires if it is a US model, or 16" for most of the rest of the world. The 16" would be 7.50-16 on split rims. If they are 15", the original size was probably 7.60-15 old style sizing, which converts to the same 7.00-15 listed above. The early 15" wheels were riveted tube-type wheels.

I just put the 7.00-15 Super Traxion on my '64 FJ40 on the original riveted wheels with new tubes. I like them a lot.

I Went the same route as OregonFJ-- after seeing his rig
 
Can those STA Super Traction’s be run in a tubeless manner or do all bias ply tires have to be with tubes?
 
As far as I can tell this is the stock spare

edit- for my 1974

The set I got (from Summit Racing) are tubeless, as long as you have the later welded tubeless wheels.

Nope, that's a Chevy wheel. Tire is one size smaller than stock on the later FJ40s, and is not a Japanese make. Plus Toyota never fitted whitewalls, ever.

Thanks for ruining my dream! Hahahahaha!

So for real, thanks for clarification. I was going to try to find out eventually and you got it for me
 
I'm running bias plys without tubes on my rig with early riveted wheels, no issues. I thought the later welded wheels were for clearance for disc brakes, otherwise no difference (?).

Riveted wheels were designed as tube-type. Large stem holes, no safety humps to retain the tire bead when flat. The rivets were never designed to be air tight, although many may be - especially if powdercoated. To be 100% safe, I'd recommend tubes in any riveted wheel. But that may just be my training from 20+ years working in the tire/wheel industry speaking.

Good Morning Everyone - I went with OregonFJ's suggestion - I went with the STA super traxion for both the FJ 40 and the FJ45 - Summit Racing had the lowest price - greatly appreciate the help everyone! Looks like the current rims and tires - just about brand new are available
