After looking all over Internet for good pricing for R4 tires an rims to fit my 2320, I talked to a very helpful JD Dealer in Vermont. This guy named Scotty I believe explained to me what I was looking for could not be found in JD-parts that it was sold in bundle numbers thru the JD salesmen who sell you a tractor, seems their parts look-up is different than regular JD parts. Anyway cost was not so bad at John Deere after comparing, the rear wheel package #LVB24803 is 16.5x9.75 rims-2 pcs & R4 12-16.5 TIRE-2 pcs cost $740.00, front wheel package #LVB24804 is 12X7 rims-2 pcs & R4 23 X 8.50-12 TIRE-2 pcs cost $420.00 total $1160.00. :thumbsup:
