The original front tires on my 1253 have finally gave up. They are the Goodyear 16x6.5-8. I have a pair of 4.8/4.00-8 wheels/tires from a tractor I parted out years ago. Has anyone used these on a medium frame? I will eventually replace the tires on the oem rims. Also does anyone have a good used pair for sale? Let me know.
