Tire Selection John Deere 4320 Compact

[1937]

I am looking to put turf tires on my 4320 with cab and was wondering what the largest size is that I can go with on the rear. I have seen these with 44 x 18 x 20, but they look a little small. I currently have the r4 tires and I like how big the tires are.

Does anyone know what the factory turf sizes are supposed to be?

Factory tires should be noted in the Operator's Manual.
