I've searched but could only find a few recommendations. FWIW, I have an E92 335i with a staggered (F)225/40/18 (R)255/35/18 setup on 189s. I don't track my car, but definitely do a lot of spirited driving. If you have these tires and have a similar driving style, what're your recommendations?

Usually, most follow the recommended tire psi located in the door jamb, regardless of whether or not tires are runflat. However, with the DWS, I have altered the psi by inflating them higher on my wife's M-B E350 4Matic, because they tend to the softer side of the performance range based on my Butt-o-meter.

I have done the same for all of the tires that I have used since switching to non-rft on my e90 with 234/40/18F/265/35/18R setup on 219M wheels (8.5x18F/9.5x18R). I pumped up the tires by at least 3-7psi front and rear.

Normal recommendation: 32psi front/38psi rear
My adjustments: 36psi front/42psi rear

I have another sticker that is yellow and red that states if driving up to and above 100mph, the recommended inflation (on my car door jamb) is:

39psi front/45psi rear

Hope this helps!

I run 36 Front 38 Rear on my DWS's with the same tire size. With these pressures I get even tire ware and good mix of traction and gas millage.

I recommend anywhere from about 35-38 PSI. Since you do some spirited driving, most likely you'll want to up the rears a bit higher for more rear end rotation around the corners. I would play around with the pressures and see what you are comfortable with.

I set mine to 40 front, 44 rear. I drive up to and over 100 out on our open roads alot. And they feel FANTASTIC so far, only 50 miles on them tops, but man, they are far and away light years better then the toyo proxes 4 I took off. Ride better and and handle far better, cant ask for much more

Same wheels/tires/sizes same car (except Xi). My car likes 38 psi cold. I mean cold cold, first thing in the morning temp. 35/36 was too low. 38 seems to be a good balance between firmness/handling and the poor road conditions around here (high CO mountains). I went as high as 42 psi and that was too much, tire felt like a solid brick on rougher roads.

Good to know they wont do great for me when we get colder. Ill have my blizzaks on by then though. I plan on running these for about the next 3 weeks then putting the winters on. Ground is so warm no snow will stick down there for a quite a while.
