Along with the manufacturer's name and the name of the tyre (i.e. Bridgestone Ecopia), there's always a set of numbers and letters that relate to the size of the tyre. As pictured below, here is a rundown on what those numbers mean:
Tyre Example: 205/65R15
205 is the width of the tyre in millimetres.
65 is the aspect ratio or tyre profile.
R means it is radial construction.
15 is the diameter of the wheel rim in inches.
94 is the load
V is the tyres speed rating.
HOW TO READ A TYRE
Your tyres are one of the most important safety features of your vehicle, especially when driving in wet conditions. Insufficient tread depth can lead to a tyres inability to disperse water when driving on wet roads.
When the groove depth is reduced, tyres lose the ability to push water to the outside of the tyre, leaving an excess amount of water between the road and the main contact point of the tyre. This is known as hydroplaning, and it decreases the amount of control you have over your vehicle.
In between tyre purchases it is important that you regularly test and measure your tyre depth's using a tyre depth indicator or gauge available from most auto retailers.
Having the correct tyre pressure in your vehicle is one of the easiest and most important things you can do for your car. The economic and safety benefits include longer tyre wear, fuel efficiency and enhanced vehicle handing.
Contrary to popular belief, tyre pressure is not determined by the type of tyre or its size but upon your vehicle's load and driving application i.e. speed. The correct air pressure for your vehicle can be found in the vehicle owner's manual or on the tyre information plate attached to your vehicles door edge, doorpost, glove box door or fuel filler door.
Generally, a tyre will lose up to one or two kilopascals (a unit for measuring air pressure) per month in cool weather and even more in warmer weather. Everyday flexing and bumps (like potholes) can also contribute to a reduction in air pressure.
Aim to check and adjust your tyre pressures once for every 2 – 3 times you fill your vehicles fuel tank – and don’t forget about your spare!

MONITORING TYRE TREAD DEPTH
MANAGING YOUR TYRE PRESSURES
Front and rear tyres do different jobs so they usually wear at different rates. Some tyres transmit drive, others steer and in some cases they do both. Their share of cornering and braking loads varies also. So regular tyre rotation is needed to help even out any irregular wear patterns and ensure maximum tyre life.
