I'm sure this has been debated here but I hope to get a few responses...

Is there any upside to going with a Ultra high performance All Season tire? Treadlife? Wet Traction? Anything?

 

It's all about tradeoffs. They are not as good as a summer performance tire when it's dry and warm nor are they as good as a snow tire when it's icy and snowing. I run them (Conti's) on my Audi A6 but change over to snows for winter but we typically get 300+ inches of the stuff here. I've found they are also pretty limited when it comes to ice and slush. They might be fine in Milwaukee's climate if you don't track the car in the summer (or drive it to its full potential) and you're content to park it on winter's worst days.

The only real advantage is that they save you from having 2 sets of tires and the hassle of changing back and forth, imo.

 

Steamboat,

Do they offer better overall tread life? All I want from the car is for it to be a daily driver that I can take everywhere and get more than 10K out of the tires..

 

For use as a daily driver they are fine and a nice compromise between the two extremes. I probably have over 20,000 miles on mine and they are still in good shape. When I have to ultimately replace them, I'll probably go with the new Conti ExtremeContact DWS offering.

 

Are the Conti Extreme Contact tires still high mileage all weather.

 

Yes, mine are an earlier version - now 3 or 4 years old. I'd suggest that you contact one of the board's tire sponsors to get their updated opinion and/or to read the latest marketing info on the competitive offerings. Damon at Tire Rack has always been very helpful.

 

Looked up the Extreme Contact tire and a set of four is around 1K.

I wanted to do some cruising the east coast this year and was looking for a tire that would handle some cold weather and a light snow if I ran into it.
I hate the fact that I have to put the car away for five months every year.
I'd love to put 20K on that car over the next year or so....

 

I would assume that the different tires would require alignment modification?

Yes/No

 

Interesting that Tire Rack doen't show any All Season Tires on their web site when searching for tires for an '07 C4S.

 

With regard to the Conti DWS, they don't make a 305/30 R19 for the rear so you'd run the standard 235/35 R19 in the front and 295/30 R19's on the back which, I think, is not a big deal. My 2008 C4S came from a Porsche dealer with Nokian snow tires in that size but you'd want to check with someone more knowledgeable than I just to make sure.

 

Re: alignment. As long as the car is within factory specifications, you should not need to realign for all season tires, imo.

 

I pulled up the Continental tire sizes and it shows the tire size for my car at 295/30ZR19 rear
235/35-19 front

2009 CS2
The car has Michelin 295/30ZR19 on it now (rear) so I don't see a problem?

 

No problems, stay safe, drive fast, have a good life.

 

Those Conti's look like a geat value, $838 for the set at TireRack!

I have Bridgestone RE 960 AS on my beater, a 2000 BMW and I'm very pleased. Looking at the specs, the Bridgestones seem to be a better handling tire in the dry and the Conti's seem better in the snow.
