Does anyone know of an extension for the full sized spare that would enable me to fill it and check inflation without pulling everything out of the trunk and pulling out the spare? I have the full sized spare. It has a lot of room inside of it when it's in the well, so I got a soft sided tub and put it in there with my cables, bungees, flashlite, etc. It would be nice to be able to check the air pressure without removing this stuff, but the valve stem is on the other side of the spare. If I could find an extension that fit it and turned 90 degrees I could do this without taking it out.
