I honestly don't know what exact model they are, I just know they are good. I can check my records in the glovebox later on. I'm at work now. But you are right Kev, there are a lot of different potenzas. I never had a problem with them in the snow. I've actually done well with them in the snow, no chains, nothing (and we get some sick winters here in Jersey). Like I said in another post though, a lot of snow driving is the driver him/herself. Tires and drivetrain do matter, but it ultimately, I think its the driver.
You guys have experienced limited use of Potenza's, like they don't last that long?
I've been different. I know I only have a 318i with limited power, but I do a LOT of driving. I have had the tires for about a year now and I have put about 35k miles on them and they are not worn that much at all. I estimate about 85% tread left on them.
I was scared about first buying them after the whole "Firestone" tire recall from Ford Explorers and Expeditions because I knew they were technically the same company. But all has been great.
