If I were you I would get it. On the day of delivery for my car the manager asked if I wanted it for some unbelievably low price due to some promotion and me waiting there for a while before my CA came back from somewhere, but I declined thinking "I'll NEVER need this"
Honest to God, not 2 minutes after I left their driveway I got a flat tire warning and when I got home their was 0 tire pressure but no nail in the tire just a hole. Needless to say I forked over $450 for a new tire.
You never know when you can curb your wheel either so for me, next time it's a no brainer.
