as some owners like the little door for the valve stem,
Some people LIKE the little door!!??? There are two ways to fill the tires without the little door.
One way is to have a 90-degree attachment on your compressor. You lie on your side beside the wheel and roll the airplane back and forth using the main gear until you can feel the valve stem. You wiggle the adapter up and get it on the stem, and then try to apply sufficient pressure to get air into the tire.
OR
You pull the wheel pant off...
I find that yanking the wheel pant is easier.
