Many thanks

There is no reason to change all four. On some older AWD cars with a thermo viscous coupling (Vauxhall Cavalier, Land Rover Freelander 1, pre-2003 MY Volvo) it is important to keep the tyres about the same circumference or transmission damage can occur. However on the later cars with a Haldex based system (all post 2003 MY Volvo) it is simply not an issue whatsoever [to the longevity of the drivetrain] how you mix part worn tyres or where the less worn ones are fitted. So yes it is absolute tosh.

AWD system apart - opinion is divided as to whether you put the best tyres to the back or front - but probably all manufacturers and most motoring bodies (AA, RAC) now recommend the rear on the basis that there would be a greater chance of regaining control of the car if it aquaplaned. However 6mm and 8mm is so close and if you put the 8mm at the front, by the time the rears have worn to 4mm the fronts will have too. In spite of recommending that new tyres go to the rear, Volvo also recommend that you rotate the tyres regularly which invariably means putting the less worn ones to the front...
