Tire Decision

[kindlethespirit]

I'm in the position that tires will need to be replaced in the spring after winter storage.

My option are as follows:

Continental Extreme Contact DWS, Z rated, 560 treadwear rating and $290.00 each
Continental Contipro Contact NOT Z rated, 500 treadwear rating and $314.75 each
Michelin Pilot Sport all season, Z rated, 540 treadwear rating and $328.99 each
Michelin Pilot Sport 4S Summer, Z rated, 300 treadwear rating and $394.99 each
Michelin Pilot Super Sport, 300 treadwear rating and $352.02 each.

I drive pretty easy. I occasionally run a bit hard, but more so in straight line acceleration, no track and sometimes a little quick in twisties on a back road. I just don't drive too fast anymore.

So with my driving characteristics in mind does anyone have any thoughts on which above tire might be the best choice? I want to have a combo of quiet, comfort and handling while not having to replace the tires every year to 2 years. I got rid of my SL500 with multiple sets of the Super Sport tires and I only got 8K miles at best out of them. Has anyone experienced either of the Continental tires or the Pilot Sport all season that have higher treadwear ratings and did they hold up for a decent amount of miles?
