Tires Trading Ag tires for Turf tires

[Mr. 5000]

I have a 2009 Kubota mx5100 and I am wanting to trade my ag tires for turf tires. What models of the kubota tractor will cross over and are there any other brands that will fit my 5100? Also is there any place to buy tires and wheels cheaper than the Kubota dealership?

Thanks Bob
