Hi, all, I'm looking for a bit of clarification re-Disco II wheel sizes. I have a Disco II with 255/65R16 tyres all round, but logging into a tyre supplier website my registration number brought me a message saying that I should be on 237/70R16. My model is an Adventurer (not Adv LE) on a 51 plate. Ant ideas or help would be welcome.
