I put a set of Potenza RE960AS Pole Position on the 8, need new treads for the 5er this spring and think I will get a set for that. The reviews were real good in comparison of other brands and models of tires. I like the tread pattern too, they seem to be silent on the 8 but I havent really gave them hell yet. To me noise wear and traction are all equilly inportant. The Falken 512 is a great all around cheap tire but are very noisey after 10k or so unless on smooth black top.
That didnt work out well at all...
