Got a Kubota b1750 4wd and starting down the rabbit hole of getting front tires for it. It’s got 31x15.50-15 Goodyear I think “xtra trac” tires. I’m pretty sure what originally came on it and the annoying 20.5x8.00-10 Bridgestone front tires. I found some tires online I like, but both are 20x8.00-10’s. Carlisle trac chief R4 tread and OTR 22 mag with R1 type tread. I’m trying to read through old posts to understand what I need to do to know if these will work and I’m not totally following all the numbers and math. I really want a R1 style traditional tractor tire for the front if something can be found, but I would settle for the R4 tread if need be. The original Bridgestones aren’t “worn out” on it, but I’m wanting something with more bite and traction for when I have the rear blade on or mowing some of the slicker areas on my property I’ve acquired. Putting it in 4wd now those turf type front tires aren’t giving me much help.

20x8-10 will work fine. Most likely will be a hair taller than your current 20.5 turf tires. You could always swap to the skinny rims and run a 6-12 front and 9.5-16 rear ag tires as well but would require different rims
I really don’t wanna have to swap wheels if I don’t have to. Wheels are still in mint shape and the back tires, while old, still have tons of tread life left and hold air perfectly. Lot of the older threads I’ve been reading have a lot of numbers and math being thrown around to calculate things making sure the 4wd can still be used safely and I’m way lost in it all.
And that tire combo is listed in the manual for the b1750 as an option. Over on the far right in the picture.
