gmmcdonald said:Another issue to consider is DSC / ASC+T I have had the misfortune of buying a used vehicle with mismatched tyres and the DSC would kick in when cornering just a tad faster than Granny would, as well as when overtaking. The overttaking one was SCARY :fencelook:
In short the outer diameter of the tyres was different enough (same size, but different brands) to wreak havoc with the traction control, and it was picking up different wheel speeds front and rear.
This look a little homework, and trust me when I was told "You don't have BMW approved tyres on your car" I thought they were on drugs.
But as soon as I changed the tyres all symptoms disappeared instantly. I have never been a fan of mismatched, but do understand that economics and availability always play a role.
But if you can, stick to the same tyres all round. There is little point in buying the ultimate driving machine and making her wear slippers on the back and track shoes on the front now is there?

or just put the bigger diameter at the back then the DTC gives you a little more rope to play with because it thinks the rear tires are spinning a little slower than they are :rollsmile:
