As for the rear tires. It sounds like you need valve stem extensions. Go to a good tire shop, farm supply store, full service truck stop, even CW has the extension. I have extensions on both tires it makes checking the pressure very easy along with filling. Get the extensions that have a solid bracket that attaches to one of the lug nuts to hold the extension. I put a pair on once that had some type of spring system to hold the extension and it was more of a pain than without.
Retired and never looked back
