I ran in to a big nail yesterday with the front left tyre
I was about 100 miles from home and despite my runflats, it was impossible to continue due to the head of the nail sticking out way to much and I couldn't get it out with my limited roadside tools.
Fortunately I have a spare tyre, took about 5 minutes to change tyres, most effort went in to putting the original front tyre (19") into to trunk
some crappy pictures I took with my blackberry
max allowed speed with the spare: 50mph or 80km/h

took me a while to get back home... being overtaken by trucks all the time, not my usual driving
The X pulls very hard to the right now so no real fun driving...
