i dont think there is an all around tire that will be good in any one condition. the all seasons like the Bridgestone re92's are ok in everything but not "good" in anything. suspension upgrades without a good tire will not take full advantage of the capabilities of the suspension. i think most find that a set of snow/cold weather tires and a set of higher performance dry tires makes for a good setup all year round.
PS, i hear the Bridgestone Potenza RE01's are great tires in dry and surprisingly good in the wet.
you should start a second thread in the suspension forum or tires forum if you want to get more into this subject. Try to keep this thread on topic for the N/A power forum.
