Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire MarkingsNOTE:
• P (Passenger) — Metric tire sizing is basedon U.S. design standards. P-Metric tires
have the letter “P” molded into the sidewall
preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/
65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size
designation for LT-Metric tires is the same
as for P-Metric tires except for the letters
“LT” that are molded into the sidewall pre-
ceding the size designation. Example:
LT235/85R16.
• Temporary spare tires are designed for tem- porary emergency use only. Temporary high
pressure compact spare tires have the letter
“T” or “S” molded into the sidewall preced-
ing the size designation. Example: T145/
