Going with the initial statement about air... How do I know if my van had air from the factory? I'm not sure if there is a thread about this, I've had a look and haven't found one. I read something years ago about the number listed on the tyre placard being indicative of air or not.
Is this true? As I have the original placard and at the time of reading, my number suggested my van should have had air con, but there is no evidence of it...
