Hi Mike,

Thanks for the informative post on: "another stupid tire thread".
Your insights filled in a few voids that have persisted in my understanding of tires for a Westy.

The word "reinforced" especially. I still remain a bit puzzled as to why the silver door sticker
designates "reinforcement" for the 205:70R X14 tire option. I follow your description (and
surmised  this myself) as to why the 185X14 "C" didn't need to be reinforced.... It already was....
so to speak!

A 205:70R X 14 load rated 97 tire at maximum inflation pressure still needs to have a
"reinforcement" designation but, only if one were to run it at "lower than maximum inflation
pressures".  Is my understanding here correct or still muddled ?
