General Questions


Premature tire wear may be caused by many factors other than tire rotation. Some examples are as follows: improper inflation, driving conditions, misaligned vehicles, worn vehicle parts, and many other reasons. Without physically inspecting the tires it is difficult to make a determination as to why your tires wore prematurely.
When replacing only two tires on your vehicle, new tires should always be placed on the rear of the vehicle.
Acura does not recommend modifying the vehicle in any manner, including changing the original tire size or the suspension. Acura vehicles meet all applicable Federal Motor Vehicle Safety Standards when they are originally distributed, and modification could affect the safety and/or operation of the vehicle, as well as remove it from compliance with specifications and standards mandated by the Federal Government. As with any modification, if a failure occurs on the vehicle that can be attributed to the modification, the warranty on the affected components may be voided.
The sidewall markings on a tire provide descriptive information about the tire’s design. The following refers to the tire illustration below with the sidewall marking of 225/50R16:

225 – This number specifies the width in millimeters (i.e. 225 mm).
50 – This number is the Aspect Ratio, the ratio of sidewall height to width.
R – Radial
16 – This number designates the tire’s diameter in inches (i.e. 16″).
92 – This number indicates the tire’s load-carrying capacity, known as the Load Index; as the number for the load index increases so does the load-carrying capacity. (All passenger car tires in the U.S. are also marked with their actual load limit in pounds.)
V – This letter denotes the Speed Rating, the maximum tire speed under controlled test conditions. (“V” in this example is one of several types of speed ratings.)
PSI (pounds per square inch) – The maximum cold inflation rating for the tire.
DOT (Department of Transportation) – This symbol indicates the tire meets or exceeds U.S. DOT safety standards; the letters and numbers following the DOT symbol provide information about the tire manufacturer, tire size, and the date it was manufactured.


Snow / Winter Tires


For most vehicles, Acura does recommend using snow tires or chains in snowy or icy conditions. Refer to your owner’s manual for information and recommendations for your specific vehicle.
This is the most frequently asked question regarding winter tires and the choice is really up to you. The answer we tell everyone is the same for every vehicle type, whether you drive a compact car or SUV. For traction, safety, and control a set of snow tires is the best option.

A set of 4 winter tires is always recommended.
An ABS braking system prevents “locking up” the brakes by pulsing them as you apply pressure to the pedal. Remember that the tires on your vehicle supply the traction and help the ABS deliver faster stops. Tires built with better winter traction will improve overall braking performance on ice, snow, and cold roads.

TPMS (Tire Pressure Monitoring System)


TPMS, Tire Pressure Monitoring System, is an electronic system that alerts you with a dashboard indicator light when your car’s tire pressure falls to the point of needing inflation.
The light signals that one or more of your tires may have lost pressure. Our technicians can quickly inspect and diagnose the cause for the low pressure and reset the dashboard indicator light.

PAX/”RUN FLAT” TIRES


The PAX Tire System is the latest in “run-flat” tire technology that, in the event of a tire puncture, allows a driver to remain in control of the vehicle and continue driving for up to 125 miles at speeds up to 50 miles an hour on a deflated tire.
Yes, the recommendation for snow chains on vehicles with PAX tires is located in the owner’s manual. It is recommended that customers contact their local auto parts store to obtain snow chains.
No. PAX wheels will only accommodate PAX tires. Use of non-PAX tires will disable the Tire Pressure Monitoring System (TPMS) and is not recommended.
PAX-equipped vehicles may be driven up to 125 miles at up to 50 miles per hour.
While tread life is determined by multiple variables that include speed, load, road surface abrasiveness and crown, driving habits and temperatures, PAX System tires should provide tread life comparable to a corresponding Michelin tire.
