I had ns2's on my 540 which was driven hard, so thats a 1.75 tonne car with 300 hp and i never ended up in a ditch.
I had no problems untill hitting a pothole large enough to bend my wheel de laminated the inside tyre wall.
If you are blaming the tires fitted to your car for ending up in a ditch or having an incident i suggest you learn to take responsibility for your driving or lack of driving talent!!
