Raising and lowering tyre pressures

[Massey 6470]

Currently have a tractor on VF tyres - so pressures need raised and lowered to get the best from them and Massey in their wisdom have fitted all four valves on the inside, have considered getting the rims Re drilled on the outsides and fitting new valves (opinions please) or maybe fitting valve extensions and directing through the hole in the massey rims to the outside but worried they may snag on something and rip the valve off.

Redrilled is the best option I would say

Redrilled some on my last tractor, stupid idea on the inside.

Have you had any bother with the rim rusting around the new valve because you broke the paint

Unless you need the track width, just swap wheels from side to side. Narrower track but all valves on the outside.

Tried that but with the spacers on the inside, the rim hit the cab before it was all the way on so rear rims can’t be turned . They’re the right rims for a dvt but the factory offset seems not to work

rim rusting around the new valve

No, I painted self etch primer on the bare metal + the ruber seal covered it as well.

If you're going to drill the rims , would it be worth drilling a 20.5mm hole and using a big bore EM (earth mover) valve ?

Anybody done this ?

Wheels on the 4x4s here have two valves, one to put air in and one to let air out. The one to let air out has no core in it. Some have a ball valve on them, others just a cap.

I've often thought of putting ball valves in the rims straight to a male coupler just use the valve for pressure.
