R4 for Kubota B8200

[fatjay]

I'm looking for a set of R4's for my B8200. The question is can I keep the same rim, or do I have to get a narrower rim? My turf tire rims are really wide. I couldn't get R1's on those rims, but can I get R4's? The turf tires are 13.6-16. Would I want the same dimentions for the R4's?

I had 12x16.5 R4s on my 2400 when I bought it. I replaced them with 33x12.5x16.5 using the same wheels. The diameters of the two tires matched so my 4wd is not affected by different diameters. Seems turfs and R4s are setup on a different numbering scheme as noted above.....was for my sized anyway. The width of the wheel vs tires was identical. Nice fit....wheel not too wide nor narrow.
