The nominal width is measured at the point where the tread meets the sidewalls if that makes sense, more or less the widest part of the tyre.

As far as I know the manufacturer has to specify the tyre rating and that becomes part of the type approval.  The new RR has a section in the handbook refering to the fitting of M&S tyres and the maximum speed, infering that they have been tested and approved with them fitted, otherwise I don't think they are legal.

You have to fit a tyre appropriate to the vehicle, for examp,e a TDi will do 98 mph flat out, so you can fit Q rated tyres (99MPH), the 3.5 V8 would do about 104 so you have to fit S rated, rated at 108 if memory serves correctly :-k

My LSE runs H rated tyres now.

lambert:
problem solved; turns out that xpc's have 2 speed ratings which are dependant on load i.e. at 1800kg axle load they are 99mph or at 2000kg axle load they are 87mph so as a disco has a max rear axle load of less than 1700kg and the tdi will only do 97 mph max i'm back to normal. yay!
