Tires

[RoykeDoyk]

For my MX, I need front tires that are the same size as the wider rear tires. I'd like to keep the same diameter to avoid damaging the 4x4 system.

Are the rear wheels of B-series trucks different from the front wheels of an MX?

Kubota has separate part numbers for the rims on the back of a B-series and the front of an MX. Are their weights different? My wheel's part number is ABR8764.

Did you end up making the swap or find a workaround that kept your 4x4 system safe? Based on what's been shared by other Kubota owners and confirmed by dealers, the part number ABR8764 is used for rear wheels on several B-series models, while MX front wheels typically carry a different part number like AMXR8828. The tires themselves might match in diameter but the rims can differ in offset, stud hole size and possibly weight. That matters when you're trying to maintain proper gear ratios and avoid binding in 4WD. If you haven't already, I recommend measuring the center hole and bolt pattern side by side before committing, as even small differences can affect steering clearance when the vehicle is fully turned.
