Hello Luke,

I just purchased new tires all around for my 50. The original specs need to be translated into modern tire sizes. I believe either an 11.2x38 or a 12.4x38 is correct for the 50. I went with the 12.4s myself.

I restored a JD 50 last winter and I put on 12.4 X 38 Firestone Field and Road 4 ply and they look great. I was told that 11.2 X 38 would also be proper on it, but a lot of people told me they would look too small, and I am glad I went with the 12.4 X 38. I am doing a JD 60 right now and went with the 13.6 X 38 Firestones and I think the two really complement each other well. My 50 had 12.4 X 38 tires on it when I bought it but they were really checked. It looks sweet with the new tires, and I like the tread pattern on the Firestone Field and Roads. Hope that helps you.

By the way, the reference to 10-38 in the old literature would equate to the current size 11.2 X 38, and the old 11-38 would refer to the current size 12.4 X 38.

I replaced the origonal rubber on my 520 last year they were 12.4 4ply tires. The new ones I used are 13.6x36 4ply. I also have a 50 that needs tires it curently has 13.6x38 on it I'm going back to 12.4 tires that were standard size because the larger tire interfear the mounted equipment on the 3 pt hitch. The wheels are set as per specs. for the plow but when the plow is raised and swings against the sway chain there is just enough tire contact the pop out the linch pin.

Luke, the 530s generally came from the factory 13.9 X 36 if the tractor was equiped with all options like fenders with dual head lights, air stack with precleaner, floatride seat, cigarette lighter, etc. We have two wide front 530s that have the above equip and are identical options.
Rear tire sizes available were; 12.4 x 36 on cast wheels, 9 - 42, 12.4 - 38, 13.9 - 36 and 11 - 38 cane and rice tires. This is specified in the 530 operator's manual OM-R20710. Hope this helps.

Put on what will work BEST for YOU....!!

The 12x38's are about right for actual working "50"'s...they may "look too big", because the rim is a little too narrow...get wider rims.!! The 12.4x36" on the 530 was entirely too small--should have been wider... The 530's could have been bought new with 38" wheels also...Listed as "rice" tires. If the 12x38 tires look too big, put 6.50x16" tires on the front,they will balance it out..then you won't leave near as many tire ruts...!!!

Luke,

An old brochure I have states that the 50 came with either 10-38 or 11-38 tires.
Another brochure states that the 530 came with 12.4-36 tires, but it also mentions 13.9-36 tires, which I think would look a little large.
