How to Choose Right Tyre Size?

Purchasing tyres for your vehicle is a big decision. Knowing your tyres size can help you making a better purchase and save your time. Selecting correct tyre size can help prevent accident and help guarantee your safety of future driving.

1, Your vehicle’s original tire size can be found in your owner’s manual, on the inside door end of the driver’s side door and on the existing tyres.

2, Write the number down and examine it. Take the sample number 175/65R14 as example. The ‘175’ represents the overall width of tyre in millimeters. The ‘65’ refers that tyre height is about 65% of the tyre width. The ‘14’ means the diameter of the wheel (tyre rim).

3, Ask Great Tyres’ team for help if you are not sure about which tyre size is correct for your vehicle.


Safety and Maintenance

Proper maintenance of your tyres will give you a longer tyre life, a safer and more comfortable ride.

Driving Habits
  • Avoid driving over obstructions such as curbs and potholes, and do not ride on the edge of the road.
  • Avoid speeding. High speeds generates excessive heat which will rise the rate of tyre wear and decrease the durability of tyre.
  • Avoid fast starts and panic stops, avoid fast turns on curves and around corners.
Air Pressure

Air pressure is one of the most important factor in tyre care. There is a maximum pressure recommended by manufacturer. You may use the inflation written on owner’s manual.

  • We recommend checking air pressure once a month and before long trips.
  • Check the pressure only when the tyres are cold. It is the best to check your tires in the morning. Or at least three hours after the vehicle has been stopped. Do not forget to check the spare tyre as well.

Tyre rotation is vital to extend the life of tyre and even treadwear. Each tyre and wheel from your vehicle is removed and change to a different position. This becomes very important for optimum tyre life. The tires should be rotated every 8,000 – 10,000km. This ensures that all of the tires wear evenly and last longer.


Alignment means adjustment of a vehicle’s suspension parts. Proper alignment will help maximize the tyre life and increase the tyre performance. You need have the alignment checked if:

  • Your wheel has hit something such as curb or potholes.
  • You have had a accident.
  • Your car is pulling one side when holding your steering wheel straight.
  • You find uneven wear on your tyres.

Balancing refers to the distribution of mass within a tyre or the entire wheel to which it is attached. It would cause irregular treadwear and increase the stress on front parts when one wheel is out of balance. You need have your wheels balanced whenever you have replaced a tire and a balance weight is moved or removed.

Treadwear Indicators

All tyres have treadwear indicator bars at 2/32″ of remaining tread. When the tread is worn down to the indicator bar, the tire should be replaced. Take your vehicle to your mechanic for inspection.
