Measure your rear rims like Kelvin said. If you have an 8" rim it will take a 9.5 tire. A 9" rim took the old 10 x tire which is now an 11.2. A 10" rim took the old 11 x tire which is now a 12.4. The fronts would be either a 5.50 x 16 or 6.00 x 16, your choice, most having been the tri-rib. As for your paint, PPG # DAR72083 H is a perfect match. I try to dissuade people from using the IH red, looks nice on Farmalls, but not Minnie Mo's; especially when sitting next to a tractor with the right color. Hope this helps.
