I am fixing up my 6060 and it needs new tires.  18.4's are almost twice as much as 16.9's,  $2600 vs $1500.   I use the tractor to pull 3 bottom 14 inch plows and a 8 ft. brush cutter.  Tires will be loaded and there are 3 weights on each wheel.  Is there a reason I shouldn't go with the 16.9's?

16.9 is the size you need. Most guys oversize the tractors with stupid lookin big fat tires. With all the weight you are going to add,---- if 16.9 dont hold it back---bigger wont either.

18.4’s will not work well with a 14” plow unless you offset it some. I don’t really like 18.4’s on 16”.

Will make a slow road-gear even slower, but that may not be an issue for you.

The rule of thumb, was to not have a tire much more than 2 inches wider than the width of your plow bottoms. Otherwise, your furrow wheel will be running on the soil you just need plowed.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

16.9x28 tires are the correct size for your tractor. If a previous owner put 18.4x28 tires on it you will need new tubes in the new tires. The old tubes will be stretched out and will wrinkle if you reuse them. I just checked with my old tire suppliers. The price you quoted for the tires should include new tubes. Do you have a loader on this tractor? If you have 3 weights on it, I cannot see you needing fluid in your new tires unless there is a loader on it.

According to AGCOPARTSBOOKS.com, the 6060 had a 14 inch wide rim for 16.9 x 28 tires and a 15 inch wide rim for the 18.4 x 28 tires.  I've never seen one with 16.9 x 28's. Always 18.4 x 28's.
