Looks like the NTS wheel has the valve stem on the inside of the rim. Not a deal breaker but does make servicing a little challenging for old cranky knees like mine. A fella could easily add another valve stem to the outside though.

Using the wheel pictured would be showing the back side if used on a 3 series since Deere suggests the wheels to be set narrow for loader work but could be used in the wide position for other chores. Maybe the 4 series can use the wheels in wide setting for loader work?

Most of 'em are two position. My stock JD fronts and rears are on my 3039R. I would prefer to run the fronts on wide if for no other reason than the more aggressive look but I mostly use mine for loader work so I guess it's best to leave mine set narrow.

Plus, it looks so danged cool!
