Just bought 2002 SSE (235/55R17) and it has Continental Touring Contact AS tires (probably the original EOM) with 6/32 thread left. They spinned several times on dry road already (with only minor acceleration from the stop). So winter is coming and I need new high performance all season tires.
I narrowed my choice to:

Dunlop SP Sport Signature and Yokohama AVID H4S.

The have similar reviews and are cost pretty much the same. Yokohama are directional, but look better. Dunlop have better reviews on snow (which I don't drive much on, but several days a year that I have to).

I read that tires might behave differently on different cars so if someone have any suggestions regarding these tires on Bonnevilles I would appreciate.
Thanks.

I've had both sport and all seasons tires. I tend to lean more to the all seasons because of the tread pattern, wear and the fact that they are good on dry pavement as well as wet.

Sport tires tend to be a bit stickier and thus have a softer rubber, which decreases their longevity.

I just put Toyo 245/50R17 all seasons on my rides and they are a great riding tire with very little road noise. They corner well and right now provide good traction compared to the stock OEM'* I replaced them with.
