I have a Kubota B4200 (1995) compact tractor, that I have turf tires and need to know the tire pressure to use on the front, 20X8X10 on the rear 29X12X15?
The best information will be printed into the side of the tire. May be hard to read or may be gone depending on age. But there will be a max air pressure printed as part of load capacity. I would say it will be something is the 15-20 psi range.
Found some 20-8-10 4 ply that run 24 psi max the Firestone G-2 29/12-15 in 4 ply are max 20 psi
