What do the markings on a tyre sidewall mean?
Every tyre should show information regarding its manufacturer, type, size, model etc. The following is an explanation of all the terminology used for both normal and low profile tyres;
Tyre example: 185 R 13 79 T
185 - Means the tyre has a nominal section width of 185 millimetres
R – Means its a radial tyre
13 - Means it will fit a 13" diameter road wheel
79 – Is the tyre load index
T – Is the speed rating, i.e. its rated for speeds up to 118mph.
Other tyre speed ratings are:
- S - 113mph
- T - 118mph
- H - 130mph
- V - 149mph
- Z - Over 150mph
- W - 168mph
- Y - 186mph
When selecting new tyres you should always replace a tyre with the same or a higher speed rating. Generally the higher the speed rating, the better the quality and technology of the tyre, this generally will give you better cornering power, more grip in the wet and increased braking performance.
Low profile tyres have slightly different markings
Tyre example: 195/55 R 15 79 H
195 - Means the tyre has a nominal section width of 195 millimetres
55 - Sidewall height is 55% of tyre section width
R - Means its a radial tyre
14 - Means it will fit a 15" diameter road wheel
79 - Is the tyre load index
H - Is the speed rating, i.e. its rated for speeds up to 130mph
A standard tyre has a sidewall height, which is 82% of tyre section width.
Reducing the % of sidewall height to tread nominal section width (the 'aspect ratio') enables tyres to be wider and put more tread (contact Pad) on the road.
Tyre Load Index
Some vehicles require tyres that are rated to carry a higher load and therefore have a higher inflation pressure. This information is usually contained in the Vehicle manufacturer’s handbook and the tyres will show the marking RF (Reinforced) or XL (Extra Load)
