Subject: Re: Which Tyres on the Rapide?
...what I've found out this evening is that 7.10x15 is 7.10 inches (7 1/4") from the outer face of the side wall to other outer face and 15 inch diameter rim. The depth of the tyre is not given but I measured it as 6 inches. So that equates in modern size to 180 / 85 / 15...which I don't think exists. My spare is 8.15x15, which is 205/75/15...which does exist - 75 is 75% of 205mm - around 150mm.
