I've got a 1975 JD410 with, I assume, original rear tires. I think they have tubes in them but the tread is severely cracking. The size is 18.4 x 24. Can the rims accept a slight size variation or 18.4 is my only choice? I may need to locate some used tires since the machine is rarely used and only for farm use and was hoping I had a better choice to find a pair. Thanks, Tom
You may find some interesting information here --- https://www.deere.com/en_US/docs/construction/non_current_products/backhoes/410.pdf It appears you have quite a few options for tire sizes.
Thanks for the link. Better than I thought for hunting down a couple replacements locally
