Tire Numbers

I have a 1943 farmall h that has a 10-38 firestone tire on it my question is when did they start using the decimal in the tire size it has about 1/2 tread and checked quite bad wondering if it could have been original ?

Thanks for any thoughts

I think '55 was the year the sizes were changed. 11.2x38 Is the modern equivalent of the 10-38. And it is possible it is original.However,I would bet it is the second.

Actually it was '54 when the new sizes came out.

I seen a 51 Super C, with the original tires on it, they were B.F. Goodrich's. They were checked, but they could easily go for another 10 years. I talked to the man that bought this tractor new, and it is still working on the same farm, I though i had done good with my 14.9 38's, they were bought new by my dad in 1964.

My dad bought a late serial number 400 new and it had 12 x 38 and not 13.6 x 38 Firestone tires. Of course who knows if tires were in the back of warehouse somewhere. I thought it was 1956 or 1957 as I have never seen a 450 IH or 720 Deer with old sizing
