How to tell your tyre size

Tyre sizes are made up of a number of different numbers and letters these are basically tyre width, tyre profile, diameter / rim size, load rating and speed rating.

For example tyre size: 205/55 R 16 91 V is made up of the following information:
Tyre Width: The tyre width in the picture is the 205 marking on the tyre. The tyre width is measured in millimetres.
Profile: This relates to the depth of the sidewall (the wall at the side of the tyre). The profile is expressed as a percentage of the tyre's width. Eg. Our 205/55R16 tyre has a profile or sidewall that is 55% of the 205mm (width). A low profile tyre is generally 50% or below, down to as little as 30% with ultra low profile tyres. Higher performance vehicles are usually fitted with tyres that have lower profiles.
While low profile tyres give you greater control and better handling on corners, they can give a slightly harder ride. Also, going to a lower profile on the same size wheels will alter your speedometer reading so you'll need to fix that up before you hit the road.

Rim diameter: This is the size of the rim diameter and is measured in inches in this case it is 16 inch.
Load rating: The load index is a numerical code associated with the maximum load a tyre can carry in this instance 91 – We can help you with what is appropriate for your usage.
Speed rating:-The tyre speed rating (i.e.V) is the maximum speed for which the tyre is rated. We can help you with what is appropriate for your usage.
