Huge improvement great package deal
Not interested –
No listing for B20 wheels. Since tires are same size, I took a chance. Lug pattern was off. I redrilled the lug holes and they now fit my Kubota B20
C. Kenneth Imler –
Wasn’t sure these would fit my tractor so I contacted customer support. Got back to me next day that they would work. Fast shipping. Just bolted them on. Absolutely perfect replacement at a fraction of the cost of Kubota brand.

Tires aren’t name brand but half the price of the kubota brand.
