Anyone have a series 4 with 14.9x28s on it. Do they look funny or not much difference. I know 16.9s look beefier but not necessary for what I use it for. ------------- Can't fix stupid |

I have 14.9 x 28 on the 6140 I just bought and I think they look puny:) They are some oldddddd Firestones at about 20% which might have something to do with it. ------------- AC 6080 (8030,7060,200,175,D-17HC, 6040,160,6140 all gone) Farmall 1066 & 656 Hi-Clear (for sale), White 2-62 High Clearance, JD 4255 Hi Clear. |

I have a D-17 IV diesel with 14.9's ---- x 38" . Looks just right. They should have all come with 38's. ------------- Nothing is impossible if it is properly financed |

| 14.9 was standard on a new one and 16.9 was a option but most were ordered with 16.9x28 our local dealer sold one new D17 ser 4 with 18.4x28s it was ordered from the factory with them. |

Does anyone know the Outside Circumference of a mounted 16.9 x 28 tire ? This would be at the midpoint of the treads. Also, the max width of same? TIA, gatz |

Those questions are answered in the tire company's Ag Tire Handbooks. The 2015 Titan/Goodyear one that I downloaded a couple years ago says the circumference is 168 inches, tire width 17.2". Diameter 56.4", rolling radius 25.7". Bias ply type R1. Preferred rim width 15" Gerald J. |

Funny how people gets used to a "look" and think it's perfect. If you have a tractore for 20 years or grow up with it. It looks normal. THen you see another with bigger or smaller tires and it looks funny. 14.9's are small for that, I think 16.9's are perfect  I would get whatever tire that matches the rim or that you can afford.
