The numbers are easy. 145 is the width in millimetres. 70 is the aspect ratio, meaning 70% of 145mm (102mm) sidewall height. R13 refers to a 13-inch rim radial tyre which makes 533mm in diameter. That 102mm side wall allows light cars to soften the disturbance of bumpy urban roads. We stock 145/70 R13 at Tyres.co.uk.
