Michelin Pilot Sport PS2 245/30 R18 BMW Alpina B3 3.3 Saloon 50 miles October 12, 2007
As fitted to my Alpina B3 3.3 Saloon - the PS2 was developed in conjunction with Alpina for the B3. As a result, they are the recommended tire for the car - indeed, the Contis which were fitted to the car when I got it felt terrible.

However - I have to say they're not the best tire on the market.

Although grip in the dry and wet is staggering, they do tend to break very suddenly. The only other tires I've experienced which do this in a similar fashion are race slicks! That said, I suspect some of this is down to the E46 chassis.

The real bugbear with these tires is the road noise - they really generate huge amounts of noise. They're noisy when new, noisy when wearing, and really noisy below 4mm wear.

The other thing worth noting is that they only seem to have 6mm tread when new!

The wear on the Alpina is shocking - around 12K on the rears.

Chuck in the ?1200 per set price, and they don't seem to be very good value.

Wouldn't recommend unless you have to fit them
