I’d have switch to 12” rim diameter like the old ZD331 to run those tires.6 ply....other brands out there.
26x12.00-12 Deestone D265 6 Ply Rated Heavy Duty Lawn Mower Turf Tires (SET OF 2)
No problem. Kubota evidently has proprietary / patent rights to this 16” tire size because the dealer was the only place to buy it last summer when my bead busted in pic.Sorry reading comprehension problem on my end...
