Thiswill produce the base line of tire which the thickness of tire may bemeasured at any point. With the use of carbon sheets, dupli-cates or manifolds may be secured, andthus give a pernanent record of the con-dition of tires at all times. This looks like a practical and inex-pensive way to make a record of tirewear, and commends itself on the scorecf accuracy, which we have never heardclaimed for many other devices for doingthis wor
