The Bentley manual says the rear rotor limit is 0.720 inches, and the front is 0.800 inches for my model BMW, and I generally am only a few thousandths above that by the time the Jurid/Textar or Akebono/Axxis/PBR pads are worn to about 1mm (which is their wear limit).
So, I do agree.
It's close to the minimum spec on a single set of pads.
I don't know.
But if it saves an ounce of lead, isn't it worth it?
you have a point, but i'd rather tire manufacturers focused on making product that didn't need as much of it in the first place. i have 4 michelin pilots on one car - the largest weight on one tire is 1oz. all the rest are either zero or 1/4oz.
Given how obsessive electronics manufacturers are about keeping milligrams of lead out of their products (ROHS standards), it's not surprising the virus is spreading to other industries.
Here is what I think the pros and cons of mounting tires is. (BMW even puts a match mounting dot on all its wheels for this.)
CON:
PRO:
how about making better wheels that don't need balancing? how about making better tires that don't need [as much] balancing?
bmw evidently haven't considered using michelin tires.
