I looked in the HBOL and it lists several 13" and 14" tyre sizes as possibles, and for space saver spares it lists either 135/80R13 or
135/80R14. If I had the 135/80R14, then the extra inch means that of course it comes out to almost dead on the same 57cm diameter as the 165/65R14s.So should I actually have the 14" 135/80 spare, not the 13" which I've got?
