I believe that you might have made the mistake of using the recommended tyre
pressures ;-) If you over-inflate by about 0.2bar you have even wear (instead
of too much shoulder wear) and less “tramlining". But my X1 feels very good
whatever the pressure. Indeed, I have recently had a puncture and it felt no
different. Mind you, the sidewalls were buggered (technical tyre term),
perhaps because the previous owner had run the tyres with too low pressures for
too long, and I had to change the tyre. But the tyre place had a replacement,
albeit a Dunlop SP2000, ready to put on.
And why have a spare wheel? You can carry a small pump and some of the repair
goo instead.
Finally, the cost of your tyres was a bit of a problem, but I can get decent
run flats for £160 a corner. And anyway, my P7s have lasted 27k with still
over 4mm to go.
So, I’m happy . . .
