I need to replace the front tires on my 4wd Ford 1710. I have both ag rims and turf rims for it. The ag tires are currently on the tractor, and I don't really plan on swapping back and forth. I'm missing a few gears that are needed for the front drive shaft to work, so R1 lugs on the front tires don't really help me much. In looking for replacements the 6.00x16 tires that I'm finding only go up to an 1800 lb load rating. That seems a little low. My rear tires are loaded and have wheel weights installed. With the loader empty and nothing on the 3pt, I'm tipping the scales at close to 4,000 lbs. So if I have enough in the bucket to start loosing traction, I have to think that I'm well over 1,800 lbs on each front tire. Is there a 6.00x16 tire available that will take a heavier load, or will I need to use the turf rims with an industrial (skid steer) tread pattern?
