I used to have the old DWS, I think those were worse. I brought them to 38 or 40. The new PZero# seem to be a good compromise esp if you have snow. I can't imagine that the AS/3+ are decent in the snow.

I think he was talking about having to change tires. I agree, it's a needless hassle for a street driven car.
I don't mind the steering response with my DWS06s but I am on 255/40R19s. Car is a good bit grippier and more responsive than on the garbage Nexen N5000s the car came with, even on coilovers.

max psi spec for performance passenger car tires is usually 44 or 51psi cold. You'll probably find the sweet spot somewhere between 36 and 40psi.
The load and max pressure rating for your current tire is probably different than the OEM one. To find a rough starting point for tire inflation, use the calculation i'm about to demonstrate for the factory 225/55r17 RSA's.
First, take the GVWR and divide by 4 tires (we're not gonna go overboard with weight distribution and so forth as these cars are fairly balanced)
4656/4=1164
next, find the max load and max PSI for your tires. for the RSA's, it's 1521lbs@44psi
1164/1521=0.765
44*0.765=33.66psi <---Hence the door sticker
Now lets look at the DWS06 rated at 1609lbs@51psi
1164/1609=0.723
51*0.723=36.87psi <---Why this tire feels super soft at 33psi. It's actually under-inflated.

Pretty cool concept, although if calculated for OEM tires (Dunlop SP Sport Maxx A1-A A/S - 225/50R18) the
implied psi = (GVWR/4) * MaxPsi / MaxLoad = (4846 lbs / 4) * 51 psi / 1477 lbs = 41.8 psi
while the door sticker says 33 psi. That would mean that road contact patch,
@33psi: 1212 lbs / 33psi = 36.7 sq in
@42psi: 1212 lbs / 42psi = 29.0 sq in (21 % smaller)
If length of the contact patch for OEM tire/psi spec is 36.7 sq in / 8" (OEM tread width) = 4.6", and I want to preserve that measure on DWS06 then
implied psi = 1212 lbs / (4.6" x 7.6" (DWS06 tread width)) = 34.7 psi
Therefore, could 35 psi for DWS06 be more appropriate?
Truth is, I personally don't even think DWS06 should be in the Ultra High Performance category. Granted it may be ultra high in dry, wet and snow traction, but definitely not in performance.
If comfort is a top priority why not go with a good touring tire which is good in dry, wet and snow? If Continental embarks on creating a performance tire then performance is what it should be. Otherwise it's nothing short of a deceptive marketing.

As far as I know, they don't even sell the DW or DWS line in Europe. It is a lower line that sells here. I can't think of a Ultra A/S that they sell in Europe and here.

Little math heavy, but this explains how calculating contact patch isn't so simple Tire Contact Patch | Lowering Pressure Gain Traction

That contact patch calculation is a bit too simplistic. maybe it would work if you were running on straight inner-tubes without any sort of structure.

You must had missed 7th grade when Pythagoras's Theorem is introduced to call that material not so simple and math heavy.
I am comparing identical size tires and approximation I am using is closer than rounding 34.7 to 35.

I think the only way for you to be sure here is to chalk the tires.

Hey Victory, you are a knowledgeable guy. I am considering exercising my Continental tire warranty to replace DWS06 with another set of Continental tires. I was just going over the warranty materials and I still have 45 days to do that. Do you know of another Continental tire which will give me similar strength sidewall as Dunlop SP Sport Maxx A1-A A/S? Will much appreciate your point of view.

i'm not too knowledgeable about specific tires that i haven't researched for my own ride. I'd suppose one of their summer tires might be stiffer, though i wouldn't run summer tires in december in NJ

It occurs to me that calculation i wrote down a long time ago is missing something since you couldn't repeat it across the board. Actually, it doesn't make a ton of sense considering passenger tires achieve their max load rating at 35 or 36psi...maybe this was something conveyed to me about truck tires? Either way, a little extra pressure definitely has a positive effect on handling.

I'm trying to decide whether to choose the Conti DSW 06 or the Mich PS AS3+ for the family G35 sedan.
Both are rated best in snow, which is a possibility in the NW. From users here who seem high on them I'm very curious about the DSW 06. There's only an $80 difference between the set
