Tire Labeling - Acura 2016 RDX Owner's Manual

MAINTENANCE
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach
five years old. All tires, including the spare, should be removed from service after
10 years from the date of manufacture, regardless of their condition or state of
wear.
Winter Tires
If driving on snowy or frozen roads, mount all season tires marked "M+S", snow
tires, or tire chains; reduce speed; and maintain sufficient distance between
vehicles when driving. For winter tires, select the size and load ranges that are the
same as the original tires, and mount them to all four wheels.
Tire Chains
Install tire chains on the front tires only. Because your vehicle has limited tire
clearance, we strongly recommend using the following chains:
Cable type: SCC Radial Chain TC2212MM
Mount chains as tightly as you can, and make sure that they do not touch the
brake lines or suspension.
NOTICE
Traction devices that are the wrong size or improperly installed can damage
your vehicle's brake lines, suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
WARNING
Using the wrong chains, or not properly installing chains, can damage the
brake lines and cause a crash in which you can be seriously injured or killed.
Follow all instructions in this guide regarding the selection and use of tire
chains.

Tire Labeling

The tires that came on your vehicle have a number of markings. Those you
should be aware of are described below.
Here is an example of what each marking means:
P235/60R18 102V
• P: vehicle type (passenger)
• 235: tire width in millimeters
• 60: aspect ratio (tire section height as a
percentage of its width)
• R: tire construction code (radial)
• 18: rim diameter in inches
• 102: load index (code indicating maximum load tire can carry)
• V: speed symbol (code indicating maximum speed rating)
Tire Identification Number (TIN)
The tire identification number (TIN) is a
group of numbers and letters that look like
the example shown. TIN is located on the
sidewall of the tire.
Glossary of Tire Terminology
Cold Tire Pressure – The tire air pressure when the vehicle has been
parked for at least three hours or driven less than 1 mile (1.6 km).
Load Rating – The maximum load that a tire is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire
can hold.
Maximum Load Rating – The load rating for a tire at the maximum
permissible inflation pressure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure
recommended by the manufacturer.
Treadwear Indicators (TWI) – The projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.
