What size R1s?

[dieselram]

I want to change my R4s for R1 ags on my JD 4300. Does anyone know the size of the rims/tires? I have a dealer searching his stuff but I don't think he knows what I need either!

I want to do the same thing with my 4610 but it's hard to find someone close to trade with. The 4310 use's 11.2-24 rears and 7-14 on the front and I'd bet your 4300 uses the same.
