I just bought a 2011 B2620 with R4 industrial tires. Dealer called and said they think they put wrong size tires and wheels on rear of my tractor at the dealer. Can anyone check their tractor that is same as mine and get back to me with tire size? My rears are Good Year, 14.2 x 16, and dealer says should be 12 x 16.5. Owners manual has a lot of different tire and wheel sizes and 14.2 x 16 is not listed as I recall for this series of tractor. Dealer says they are for the 3030 series. Help me out here guys, they are coming today to swap them out. HJT
