Spare or donut tire: Although many car manufacturers now include a short-term donut tire with new cars, a few still include a full-size spare tire. It is usually located in the trunk or under the ...
To take a common example, 195/55R16 would mean that the nominal width of the tire is approximately 195 mm at the widest point, the height of the side-wall of the tire is 55% of the width (107 mm in this example) and that the tire fits 16-inch-diameter (410 mm) rims. The code gives a direct calculation of the theoretical diameter of the tire.
Chalking a tire is an old-fashioned technique used by many municipalities for checking to see if a car has overstayed its time in a parking spot.
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers.
