Anyone have any experience with the Dunlop SP Sport D87M in 215-50-15 on 15x8" wheels for the ur-q? Tire Rack has these for < $100 each...... Are these 'high-performance? All-season? What new Dunlop model obsoleted them? No luck finding P700Zs Stateside and not a lot of options in this size..... TIA, -glen
