Kubota B5100E front wheel Conversion?

[Rob_Aussie]

Hi all I have a Kubota B5100E 2wd it currently has the 4.00-9 tyres on it. However here in australia you cant get them anywhere it would seem.
Has anyone successfully changed the size to a bigger option for the R1 tractor style tyre?
perhaps a 10 inch rim or 12 inch rim? TIA

With a 2wd the world is your oyster, common sizes are 20x10.00x8
Rim is 4 on 115mm, Very common rim.
You will want a steel rim because you might have to cut the centers as it's a large pilot dia of 90mm

Do you happen to know if there are rimes bigger than 8" that will work perhaps 9 or 10?

Thank you for the already given advice

Really any size will work with the right bolt pattern, center diameter and rim offset.
One thing to keep in mind if you go too tall on the front it's going to adversely affect implement use.
