<<Are tyres made of precisely the same ingredients wherever they are
manufactured?>>

There is one 'bingo', Simon !!!  Even tyres coming off the production line
one right after another would not be the same (not MUCH difference, BUT
still 'different'.

2nd would be the 'roadway' composition !!

3rd would be inflation pressure, tyre total age and mileage(s).

4th, I would surmise that rain here in Chicago is not going to be the same
as 'on the range' in say, Wyoming<G>!!

What 'drifts' on your side of The Pond may very well NOT 'drift' on this
side !!  er, OR vise versa<G>.
