A couple 4300 questions.

A little addition here:

The R-1 Ag and R-4 Industrial tires are not reversible. These tires are unidirectional for traction. There will be an arrow embossed on the tires' sidewalls to indicate the correct direction for mounting.
So, R-1's and R-4's are actually swapped side to side.
R-3 Turfs are reversible.

If those tires aren't filled with liquid ballast, I suggest you do so. That really helps with stability!!

BTW, I have a 4400...same machine as yours with a bit more horsepower.

Deere recommends only one position for the front wheels when using
R1 or R4 tires. You don't really gain any stability in the front anyway,
since the axle pivots in the center.

They DO say it is OK to run these tires backwards in the front only
to assist in backing up when doing lots of loader work.
