AMERICANO !!  - Bah humbug.  If you want it black, you'll have it how it comes, and how it comes is espresso, pure, unadulterated, triple shot, light roast, fresh bean espresso. My Brughnetti objects to having hot water thrown into his output.

He will with slight protest allow the shots to be adulterated with 59c textured milk, but not watered down just for the sake of satisfying thirst...
.....americano . . . americano . . . .  apologies to any from the continent above Brazil etc, . . . but really, we're talking coffee, and that is a matter of life and life... or something.

Yes, you are very right, the addition of a tyre lathe/truer, any truer used well, will improve the feel and ride of your cars greatly. 
You will be surprised at how anal you will get over time, in getting each car's tyres  " just right "
