Tire Valve Always in the Wrong Place
I saw a post here that I can't find now about the tire valve always being in the wrong place when you need to check or air a tire.
Simple solution and I'm surprised everyone doesn't do it; depending how anal retentive obsessive compulsive you are, add 2 or 3 rim locks! Drill a couple holes and you'll have valve stems every 90° or 120°! You'll never need to rotate a tire to check pressure again.
Sadly, this only works on tubeless tires unless you want to add valve stems to a tube, but that seems like an awful lot of work to me.
