Tractor weighs 2675. Loader weighs 700 lbs. Total 3375. Front tires are rated at 1320 each, rear at 1570 each, 5780 lbs total. I think the tires are spec'd for enough weight.
My only choices are 6-ply and 4-ply. I wish they made an 8 or 10 ply in my tire size.
I guess I will go with 6-ply turfs and see how they hold up. I had more or less convinced myself of that earlier and the responses bear that out for my needs. I do more digging and grading with the loader than hauling, and getting stuck isn't an issue, so I will likely be better served with the turfs.
Thanks!
My pocketbook tells me not to believe that. $1600 for a front differential repair on a Ford 2120 that the Ford rep tells me was caused just by inflation issues.
Can I use a different size tire on my 4wd tractor
In their example, an acceptable rolling circumference would be 126.9" - 131.9". That equates to a tire diameter of 40.4" - 42.0" at perfect specifications for the front tires leading the rears. You could also let the rears leads the fronts if backing up through muck was more important or let them be equal for no leading. That gives you a range of 38.0"-42.0" for what the axle was actually designed to handle under optimal conditions. So like I said, an inch here or there doesn't make much of a difference.
Now if you ran them continuously without enough air, you probably went significantly past 1" here or there because you not only decreased their size with less air, you then also wore out the tread for even more of a loss, and likely put more pressure on the axle bearings because the tires weren't handling the load. Hence your troubles. Not that I'd be entirely convinced of that anyway, I'd assume something just failed or that it was used excessively where 4WD wasn't appropriate, but thats just me.
