Recently comparing the new 3720 to my 4300, I came upon the tire/wheel spacing options in the manual stating the available sizes offered and acceptable for both units and it appears that the 3720 is limited to the 11.2-24 R1 Rear and 7.00-14 R1 front tire while my 4300 states that a 12.4-24 6Ply R1 can be installed on the rear and 7.00-16 R1 available for the front. What's up with this??? My 4300 only has 32 gross HP while the 3720 has 44 gross HP and I would assume the bigger powered tractor would also allow the bigger R1 Wheels and Tires. Seems kind of out of whack! Anyone have pictures of their new 3720 with Big R1's or can you only install the smaller ones?

Good question,
and right now, only small rubber available in the R-1,,
:confused:

The tractors do have different gear ratios, and finding
compatable fr and rr tires to stay within overrun spec
is a bit challenging, but can be done. would require
larger rim for the front, and i believe only a 12.4 rear
width will work.

I have had a few people change around, because after
getting the tractor they could'nt stand to see it on such
small tires.. both had prior tractors with the larger tires.

Ever seen R1s on a 3X20? Pretty weird and skimpy looking.

Get the large R4s. I have the small R4s and they are great. They are on my 3320.
