Maintaining the correct pressure is the easiest, yet most important thing you can do to get the best performance, economy and safety from your tyres. Information relating to the correct pressure should be available from your vehicles's tyre placard.however, considering these points may help:

Differenct driving conditions require different pressures. For example, a higher pressure is usually recommended for high speed driving or when carrying or towing a heavier than normal load. Seek advice on what is best for you and your car. Tyre pressure should be checked when tyres are cold, as pressures will increase when tyres warm up. Under inflation of tyres can cause them to experience uneven or rapid tread wear, as well as lead to an increase in fuel consumption. In addition, under inflation reduces your vehicles brake and handling capabilities, and can ultimately lead to serious tyre failure. Where possible, carry your own tyre pressure gauge. Sealing valve caps must ALWAYS be used, the best being the metal type. If you require any assistance with the pressure of your tyres, see your local tyre retailer.

 
Regular rotation of tyres is a proven method for promoting even wear and therefore extending tread life.

If uneven wear has occurred, this may be due to worn suspension components, vehicle misalignment or incorrect tyre balance. These concerns cannot be corrected by simply rotating the tyres. These problems should be corrected by your local tyre retailer.

Front to back same side rotation is acceptable when tyres are wearing unevenly.

If the spare is included in the rotation it should be exchanged with the tyre allocated to the right hand rear position.
      
Note: Tyres will directional tread designs must remain on the same side of the vehicle.
75 and 70 Series

Popular on many small and medium cars, where they provide good ride, comfort and durability.

65 Series

Tyres with 65 series aspect ratios are popular fitment on many medium and large family cars. Improvements in handling while retaining good ride are key performance strengths of this type of tyre.

60 Series

Further improves handling, particularly steering response as sidewall height is reduced. Popular fitment on sports touring vehicles.


55, 50, 45 Series and below

Very low aspect ratio tyres developed for the new range of higher performance vehicles where ultimate grip for braking, steering and traction are the priorities.
P Indicates passenger vehicle tyre construction
C or LT Indicates commercial or light truck tyre construction
205 The section of the tyre in millimetres when fitted to the design rim.
65 The aspect ratio - the sidewall height is 65% of the section width
R Radial construction
15 Wheel diameter in inches

95 The load index is a numerical code; in this case '95' indicates the tyre has maximum load carrying capacity of 690kgs.

H Speed symbol (H=210km/h). The maximum speed at which the tyre can carry it's rated load.

S - 180km/h
H - 210km/h
V - 240km/h
Z - over 240km/h
W - over 270km/h
Y - over 300km/h
