Thought I would collate and put into plain english the basic info required for sizing the tyres into one place, as there seems to be lots of info scattered all over the place and some of it was missing! Fabia MKI OEM Sizes 155/80 R13....Don't know if it was a standard UK fit, but it is listed on the fuel filler cap! 165/70 R14 185/60 R14 185/55 R15....Listed as the winter tyre size as chains can be fitted to this (for cars with OEM 195/50 R15) 195/50 R15 205/45
