Substituting light Truck Tires 33-12.50-15 for Goodyear Turf Tires

[Yourkie]

Does anyone know of inexpensive usable turf type tread tubeless truck tire in 33-12.50-15 NHS (1989 755 Deere compact utility) that I can substitute for my OEM Goodyear Turf Tires (Terra Tire Soft Trac 4 ply in that size. I bought the tractor new in 1989. It has only 1108 plus hours and has always run well. The original rear tires still have tread and hold air but are getting questionable from sidewall cracking. I only use it for minor mowing and light loader work.

Is there a good reason not to use truck tires as a substitute? The new turf tires are $400+each and Id rather not spend it if not needed. They have never calcium solution in them. Any other thoughts are appreciated. Thanks.

I've done this before. You just go to a tire shop that's willing to work with you and figure out an equivalent size. I went with their recommendation and we just stood the tires side by side to confirm that they were close enough in size. The new tires were even radials.

You can get that size at Walmart for less than $200 each for M/T tires. The metric size would be something like 315/75R15. The difference may be the rated ply. As long as you're not driving over rocks or stickers, they should be fine.

I just bought some Goodyear Wranglers for my truck for less than that. I haven't mounted them yet. I have new wheels too but trying to get my balancer working again first. My new tire changer will handle up to 42" tires.
