You have to be careful of tyres !
I was in France once with a few friends. One had a Porsche 996 GT3 RS. We were out at a restaurant at night and on the way back, one of his tyres blew out. Luckily we were not pushing the cars hard as it was late and he managed to control it without any damage. We put the small size spare on and got back to our accommodation.
The reason for the blow out was due to his tyres being 12 years old ! Due to only using the car for special trips and therefore low mileage, there was lots of tread but the rubber had hardened and become brittle causing the blow out.
Needless to say, he went hunting for four new tyres the next morning and taught us all a lesson.
I am in North London, near the Hertfordshire and Essex borders
