Hi, I have a 2000 1.8 QTS. 3 of my tyres need replacing, the remaining good one is a pirelli p6000 on the n/s/f. Given the quattro system do I need to do a like for like replacement i.e. should the tyres on each axle be the same make and have the same tread pattern? I am sure I have read this advice somewhere before but wanted to check. Don't really want to keep the good P6000 as not very impressed with them, and I may sell the car soon and would rather put cheaper tyres on the car. Thanks for any help you can give me.
