What types of tyres are available and how do the sizes work? – Help iGarage

The tyre size consists of width, height and diameter of the rim

For example: width/height/diameter => 205/55/R16)

Three types of tyres are possible

Summer tyre
Winter tyre
All season tyre (Here in the UK almost all tyres are all season)

The legal minimum tread depth is 1.6mm although tyre and safety experts believe the 1.6mm legal minimum is insufficient to guarantee safety and tyres should be replaced when they get down to 3mm.

If there are any bald patches, uneven wear, cuts or damage especially to the tyre wall do not drive your vehicle, either exchange with the spare wheel (if you have one) or get to a garage as soon as possible.
