Set of 4 labels for marking wheels in storage - just put this under valve cap - no need to mark tires again with chalk/marker.
 

Polish version was made long time ago in Sketchup
As exercise, I created customizable version with OpenScad

just enter your preffered langauge abbreviatons for left, right etc and print

Font is popular one - so label will hold only contour of letters - you can substitute stencil font - that way letters will have internal contour  - but be aware that it will be prone to damage  anyways :)
