Tires Pirelli or OEM BMW

I'm pretty happy with how things came out with the tires. We really haven't had any snow where I live to really try them out, but in the cold weather, even the dry traction is worlds better than the PZeros that came on the care---despite being an inch smaller and a good amount narrower (235 vs 255).

After seeing the performance of Pirelli in WRC, and some of the direct massive pothole shots my OE Pirellis have taken, I'm impressed with them

I've been happy with my Pirell P-Zero Nero M+S... Good in cold, wet, slush, muck and even a few inches of snow... very good in the dry too.

My original Pirelli's were loud after 10K miles. I couldn't wait to get rid of them. The Yoko's are very quiet with exceptional handling characteristics.

I love my PZero Nero M&Ss. They're VERY confident in the wet.

Including like new Pirelli P Zero Rosso 275/40ZR19, these puppies were $1380 delivered. The rims are flawless and I can recoup some money by selling the "B" centers. Tonight they are go on the car.

Both my cars wear Pirelli Winter Carvings in the white stuff. Very happy with those tires.

Car feel slippery, sway little left to right constantly when on freeway (I noticed it only does that when at high speed--freeway speed--especially when vehicle is running on those comb-lines cement paved.

I agree with the above poster; the Pirellis were less then impressive. Im at the end of the life of my 2nd set and have gotten 36K out of the 1st and 31K out of the second. They have cupped horribly, and consequently they are noisy as hell.

The Factory 18" tire is the Pirelli P6, not rated so well either but not anything as bad as those Goodyears.
