I was just changing the tires on mah Twingo and I thought about something I'd like to share with you. I've had it with my Volvo and now with my Twingo. If your car has different tires on the front and the back and is a bit twitchy on subtle steering, sensitive for wind gusts or even just pulling to a side, don't panick; Swap the front tires to the back and vice versa. Some tires don't track very well together. Can save you a headache and a lot of money. Worth a gamble!
