1.Tire Pressure


Importance of Tire Pressure

  • Optimum air pressure should be maintained to ensure safety, driving performance, tire life and fuel cost.
  • Tires have been known to lose usually up to 1 psi in a month (psi : pound per square inch), therefore, it is important to check all tires, at least once a month or before a long trip.
  • Recommended Interval
  • Tire pressure should be checked every month.
  • Checking for Optimum Tire Pressure
  •                                  Driver’s side door                                                                             Inside of fuel tank cap

  • The optimum air pressure level for your tire can be found on the inner side of the car door, inside the fuel cap or in the car manual (the location of the sticker can vary according to country). 

  • DO NOT compare your inflation pressure to its maximum pressure marked on the tire’s sidewall.
  • How to Check Tire Pressure
  • 1) Purchase a certified air pressure gauge or take your vehicle to a nearby service center (or gas station) for a check-up.
  • 2) Tires must be checked in a “cold” state (at least three hours after driving). 
  • 3) Insert the gauge into the valve.
  • 4) Compare the measured air pressure level with the level listed on the car door.
  • - in case of higher pressure than a recommendation, deflate your tire to the recommended pressure.
  • - in case of lower pressure than a recommendation, inflate your tire up to the recommended pressure.



Importance of Checking for Tire Wear

The deeper the groove, which is a circumferential channel or drainage road, the more grip a tire will have. You can prevent an unexpected accidents by checking for tire wear regularly.


Recommended Interval Between Check-ups

Crowntyre recommends you to check for tire wear once in a month. Also, make sure to do a check once more after long distance travel.

Tire Tread Wear Indicator

You can check for the depth of the groove by using a Tire Tread Depth Gauge or by observing the Tread Wear Indicator on the bottom of grooves, the location of which is marked on a shoulder as “▲”. To ensure optimum safety and performance, tires should be replaced when groove depth remains less than 2mm.


3.Tire Rotation

Ideally, tires should be rotated every 3,000 to 5,000 miles. When this is done consistently, the tires are more likely to maintain good handling and traction and deliver maximum tread life. However, it's important to remember that tire rotation alone cannot guard against rapid or uneven wear if your vehicle has faulty mechanical parts or improper tire inflation pressure.
