Information & Advice on Car Tyres

Tyre Size Info

The first thing you need to find out when purchasing tyres is what size you need. Simply check the size of the tyres currently fitted.

The size of your tyres should be displayed around the sidewall of the tyre.

It will be in succession 195/55 R16 87V, and mean the following:

195 = width (mm)
55 = profile (mm)
R16 = rim diameter (inches)
87 = maximum carrying load
V = speed rating


Tyre Labelling

From the 1st July 2012, European regulation states that all tyres within the EU must be labelled with performance information in a graded diagram.

The performance grading is categorised by fuel economy, braking in wet conditions and external noise, helping you to understand your tyre choice better.

Fuel economy performance is measured in a similar way to household appliances and is graded A to G, A being the highest and G being the lowest grade awarded. Tyres can have a big impact on the amount of fuel your vehicle consumes, by choosing four A grade tyres you could save yourself approximately 80 litres of fuel over the lifetime of the tyres.

Braking performance is also graded A to G in the same way. The lower the grade of a tyre, the longer the braking distance. The difference between grades can be up to one or two car lengths in stopping distance.

The third performance label concerns the external noise the tyre will make when driving. The noise level is measured in decibels, illustrated by black sound waves. There are three levels, one black wave means the noise level is low, two black waves mean the sound generated is average and three black waves mean the noise level is higher than that of the EU limit.
