I've been looking to replace the stock Mich's with Pirelli P-Zero Nero M+S 235/45 (even though I live in 3 season So Cal. because I want a decent quiet ride with good tread life. Now this new Kumho ASX comes out and is $120 cheaper per set. I've done a ton of research which led to the Pirelli decision. Has anyone tried the ASX yet?

 

I put the Pirelli P Zero Nero's on my 2001 CL/S and took them back and had them replaced because I couldn't stand driving on grooved freeways where the tread pattern followed the grooves and the car snaked down the road. They're a great tire but the groove problem makes the driving a chore. BTW after the Pirelli's the dealer put on two sets of Michelin Pilot Sport A/S within a week and both these sets caused the car to pull to the right. Now running Conti Extreme Contacts 225/45 17 on the stock wheels and they're fine
