Seems that i've heard them called rice patty tires.They look specialized. Maybe if you had to work around a nursery for instance. Well drained soil, no grass, you need a little extra traction but you can't have the agricultural tires ripping up the ground around your trees/plants. Just thinking out loud.
You are referring to R-2 "Rice and Cane" tires.Seems that i've heard them called rice patty tires.
You lose an inch of radius compared to the turfs.I had them on a B2400. No good there because they were shorter than the standard tires and you lost all ground clearance. If you can get them in the same height as your regular tires they would be allright.
On B2920 options are 11.2-16 R1 AG
33x12.5-15 Turf, 31x15.5-15 Bar Turf
12x16.5 R4
Bar turfs are two inches lower and 3 inches wider, I had these on B1750 many
years ago and they were fantastic, great on grass and great in snow, had R4's
on L3010 and they were hards as rocks, poor traction in snow and had to keep
off the grass. If I am able to get a new B2920 this year it will have the Bar Turfs.
