Hello all. Im new to this forum. I have a ford 1310 4x4 tractor with 13.6/16 turf tires. I am trying to find ag or industrial tires and rims for the rear of this tractor. According to the manufacturer that is the only tire capable of fitting on my rim. The tire size that they say fits is 12.4/16 on rear and 6.00/12 on front. I have located the front rims and tires. I know some of the other brands like kubota use the same size tires. So I guess what I need is a 16 inch rim with a center hole size of 4.5" with a 6 bolt pattern. Center to center on bolt hole measurement is 6.75". I am willing to trade rear tires or buy if the price is reasonable. Thank you all for your time and glad to be on your forum.
