JD 2320 rear wheels in wide configuration so valve stems are on inside. I want to be able to reach from outside of wheel so i can get an air chuck on them. Any suggestions?

Drill a hole in the wheel center of each rear wheel and then add flexible extensions to the valve stems. Use the drilled hole to mount the input on the extension so it isn't flopping around.

In thinking about this just a bit, you probably don't even need to drill a hole. The wheels have 4 square holes to hold the bolts for wheel weights. I bet you could feed the flexible extension though one of those and put a washer and nut on either side of the wheel to hold it in place.

I'd just drill another hole for a bolt in valve stem where it doesn't interfere with anything. Should be no big deal.

So I went to my local Camping World store and got flexible valve stem extensions designed for dually wheels. Long enough to reach thru holes already in wheels. Secured to outer wheel with provided hardware. Thanks for all the input.

Are your tires liquid filled..??

How often do you need to check your tire pressures? I'm in the same boat as you, wide-set on the 2520 also puts the valves on the inside. I've had my tractor 3 years and have checked pressures maybe once. I mainly look for the sidewall to settle and the contact patch to get bigger to tell my tire is low.
I do wish the manufacturers would keep this in mind and put a valve on each side of the wheel, 180 degrees apart.
