Often used on compact and mid-range cars, 195/55 R15 tyres are available in a wide range of models at mytyres.co.uk. From premium to budget, you will easily find products that suit your needs. The size description contains some of the most relevant information for ensuring a perfect fit for your vehicle.
First, the number 195 indicates cross-section width, expressed in millimetres. This is measured from sidewall to sidewall, when the tyre is mounted onto the rim, and without supporting the weight of the vehicle. Small variations are normal, so this is an approximate value.
Connected to this is the aspect ratio indication, the number 55. It gives us sidewall height, as a percentage of width - here, 55% of 195 mm. The R' is the marking for radial tyre', the most common constructive type. The number 15 refers to inner diameter, letting us know that 15 inch rims are compatible with this tyre.
