Curious on your 38PSI front, 32PSI rear (cold) for road tire pressure (commuting). Enquiring minds want to know.
I draw from my years of autocross experience to run my own tire pressures, all in effort to balance contact patch, wear, stability, and comfort.

Saab recommends for my car on 17" tires, 35psi all-corners for light loads and 41psi all-corners for heavy loads. These are general "safe" numbers for regular people, but neither are ideal for all conditions.

My two problems with these recommended pressures are that either:
1) They're too high and not comfortable for my lowered suspension and 18x8" wheels (235/40/18).
2) Too low and doesn't support the front adequately.

Let's start with the front axle. These are very front-heavy cars, even the 2.0T engine. I often found that with 35psi, the tire would roll over a bit past its outside shoulder treads and onto its sidewall during turning. And I felt like I wasn't getting all the traction and poise that the tire had to offer. After a lot of testing I felt that 38psi was a good balance of contact patch and comfort. Ride quality at 41psi is punishing.

Now let's move onto the rear axle. This car being very front-heavy, the rear doesn't get a lot of load placed on it. You can see that by looking at the tire tires after driving on a dusty surface. At 35psi, not all of the tire tread even makes contact with the ground. Maybe only 3/4 of the inner treads regularly contact the ground depending on your camber setting. This is a sign of over-inflation which means your ride is not as comfortable as it can be, and in the long run can lead to uneven wear. I found that 32psi gives a proper even contact patch and ride comfort is better.

Of course results from car to car will vary depending on rim size & width vs the size & width of the tire in relation, and the individual characteristics of the tire play a roll as well (like how stiff the sidewalls are).

Anyways for those wondering, my alignment is usually in check and I've never had uneven tire wear unless I was intentionally over-inflating for the track or the tire had seen a lot of corning abuse. Also I'm well aware that higher pressures in the rear vs the front for FWD cars give a more neutral and almost tail-happy handling, but I just don't drive like that every day.

Impression so far (describe): Michelins demand a higher price for a reason: they are exceptionally good all-around perfomers. I've driven my 9-3 Aero aggressively and while the tires do wear more than other A/S I've had on other cars over the years, the grip, noise, comfort, and durability is all pretty impressive. Even after 7 years, they show very little sign of breakdown. And you can get a full sent for about $600 now, not bad by Michelin standards.

Equivalent to most other tyres I've used in the warm and dry.

In the wet, exceptional. Aquaplaning is virtually non-existent. The water simply flies out the sides, nothing comes up over the hood.

The tread pattern is like an agricultural vehicle with all the treads faced across the width. Most summer tyres have radial treads and winters a combination of both. These look like a racing JCB would have! :cheesy:

Waiting for Snow and Ice now.

Your car: 2009 Saab 9-3 Aero XWD
Price paid: came with car
Vendor: N/A
Miles/KMs driven so far: 600
Impression so far (describe): Came with the car I bought. They are relatively new as they have about 8/32 left in the rear and 6/32 in the fronts. I have the same set on my wife's BMW X3 (used both the original and the Pluses) and the behavior on the 9-3 XWD is very similar. It gives a very composed ride and is EXCELLENT in wet weather. I have never tried these in snow.
Overall subjective rating (1=poor/5=excellent): 5
Other comments: Have not tested them in snow yet. My wife's set lasted for about 35,000 miles before replacement. They get very unsettled towards end of life and lose their grip significantly at 3 to 2/32 depth.

Miles/KMs driven so far: 12,500 miles
Impression so far (describe): First off, these were bought with 5,000 miles on them so keep that in mind. The tires, they are actually my favorite tire to date. They have a good amount of grip and feedback. They wear well and even and do well in the snow. Better than expected for a non-dedicated snow tire. They are however, the noisiest tire I have had.
Overall subjective rating (1=poor/5=excellent): 4
Other comments: Very good tire for someone looking for an all season that will see snow use. If tire noise is an issue, perhaps your exhaust isn't loud enough.

Other comments:
Had these installed last year in late spring 2015. This is the first time I pleasured myself with high performance Y rater summer tires so spent the summer driving fast and hard (but not like an *******). By the end of October the front tires had excessive outside and inner tread wear; fronts are no good for a second season. Tread wear on the back set was minimal. Will buy two new ones for the front this summer and consider increasing tire pressure to minimize outer/inner tread wear.

Only downside was in wet conditions. Yikes!!!

Model: Pilot Super Sport
Type (summer/all-season): Max Performance Summer
Size (tread width/aspect/diameter): 225/45/17 on 7” wide rim.
Your car: 2005 Saab 9-3 Aero Sedan w/ stock Aero springs and Bilstein dampers.
Price paid: $1030 CAD including taxes and installation.
Vendor: Tires23.com
Miles/KMs driven: 21,758km including 1 track day and 12 autocross events.

Impressions on the track: Brilliant dynamics though not as extreme as other track focused tires. Progressive grip up to the limit and it’s audible to let you know. Turn-in is very sharp and makes my car’s passive rear wheel steering (ReAxs) come alive. This makes chucking the car around really fun. Confident traction in the wet. Rubber compound withstands abuse quite well, except Saab got it wrong recommending a 225mm section tire on the stock 7” rim which made the tire rollover on its sidewalls wearing them down quicker than the rest of the tire.

Impressions on the road: Stiff sidewalls which were good for handling, but don’t absorb big bumps well. Hits from potholes and expansion joints are jarring and get worse as the tire wears because there’s less rubber to squish around and absorb the impact. On the bright side, tread noise is very minimal overall. Little rolling resistance means easier coasting at high speeds and better MPG. Good treadlife for what you get in performance. Very safe in the wet and resists aquaplaning.

Overall subjective rating (1=poor/5=excellent): 5.0
Other comments: Track tire pressure = 44PSI front and 45PSI back (hot). Road tire pressure = 35PSI front, 36PSI rear (cold).
These are superb, I got them from Costco. $540 for the set with install.

I live in Hawaii and I push them to the limit in the dry and in the wet and they STICK even in torrential downpours.

But they wear fast I am about to install the second set after around 11K miles

Price paid: Neighborhood of $600, I think. This was years ago.
Vendor: Tire Discounters in Florence, Kentucky
Miles/KMs driven: Lots

Impressions on the road: These tires have now reached the end of their lives and will be replaced tomorrow. When new, these tires handled well and were reasonably quiet, though not the quietest I've ever had. Rain traction was not the best when new, but passable. I don't drive when it snows, but I have been caught in unexpected wintery weather and snow traction was, and still is, the worst I've ever experienced from an all-season. Now that they are old, noise levels have ramped up significantly. Even though there is theoratically enough tread left to last me several more months, the wet traction is straight-up dangerous. I never imagined that a tire could be this dreadful in the rain. They hydroplane with the slightest provocation and hitting a surprise puddle makes me pee a little.

Overall subjective rating (1=poor/5=excellent): 2 - I will never buy these again.

Other comments: Tomorrow, I'm installing General Tire Altimax RT-43. Reviews on them are consistently very good. I will report first impressions on them at a later date.

Impression so far (describe): Comparing these to my worn out Continental DWS tires is difficult since I didn't get the DWS' brand new. Plus I've only had them for a very short time. However, the grip is amazing, both in dry and wet. I'm very impressed and the cornering is phenomenal. There is a slight bit of road noise but I think it's due to them being brand new and a slight wear will help there but it isn't unpleasant and could just be because I'm thinking about a new purchase too hard. With a 45k tread warranty these are an excellent buy and they are almost like driving on summer tires. This was on my short list of UHP all-seasons and in the end it won out based on the strong reviews on Tire Rack and on Discount Tire's sites combined with the tread warranty.
Overall subjective rating (1=poor/5=excellent): 5
Other comments:
other options in this UHP-AS range include the RE970-AS Pole Positions, the DWS, the AS/3, and a few others. These are basically the highest end all-seasons available in this upper price range.
I don't think there's a way for me to edit the original post....unless a moderator wants to combine them.

UPDATE:

I still give these a 5.

The tire noise calmed down after the initial 500 miles. They still aren't as quiet as my old DWS', but they are firmer in the corners. My only complaint is that they aren't as sticky as summer tires. I can't knock that, as I haven't found any all-seasons that are.

Wet traction is amazing. I don't think I can recall slipping/hydroplaning in a situation that would have caused the DWS to slip at all in them the entire time.

If you live in a temperate climate where you don't swap between summer and winter tires, then these are an excellent all-season tire to keep on 365 days a year.

I'll probably try the Michelin Pilot Sport A/S3 next time just for a change, but they would add another $150 to the bill for 4.

I was around 25k miles on them, but got new 18s so had to buy new tires. I bought another set of these for about the same price out the door.

Wow, sticky, even in the wet. Tracks straight, even in higway puddles. The safest tire I ever got. Noise? Who cares! Not so bad. Less than winter tires anyway.

Just because of the fast wear. I knew about it, it's no surprise.
Other comments:
DO NOT drive these tire if the temp goes below 5C/40F. They become as hard as ABS plastic! :eek:
-About post #49, "Only downside was in wet conditions. Yikes!!!" I do not understand how this can be. Maybe different tire pressures?
I inflated mine at 40-42 PSI.
-Why didn't I bought those tires again, after 2 years? I wanted ONCE in my life to have a set of ZR killer summer tires. Not financially reasonable, but hey it's off the bucket list. :lol:

Time for new tyres. I've had some Michelin Primacy 3 on and these give a very sure turn-in and less understeer than everything else I've tried. But I do like the cross climate. Not as sharp in the dry, but on wet roads, grass, mud and dirt, they are much different to other all-season types. Not in fear of getting stuck unless it's up to the sills. When in the weeds on a single track lane, to avoid a tractor I get no wheelspin or slithering like a normal tyre will. Unless you boot it of course.

We've had a very mild couple of winters and I've not had a chance to compare on ice or snow. The Primacy also works well in the wet and I've had no scares - but then it hasn't been that wet either!

Wear isn't much different to other types. But now everyone is liking the cross climate, the price has gone up!

I'm also Hunterised and camber adjusted at the front. My tyres wear very evenly. I run 39PSI all round.

For all season = 5.0
For summer = 4.5

These are fantastic. They're quite grippy on dry pavement and the best I've ever had in rain. They're even shockingly good on the snow, almost as good as any winter tire I've ever used. They also track much straighter than the Michelins I used to have. The price is great too. I will never again pay for overpriced big-name brand tires. These put the Michelins to shame. I like them so much I'm putting them on the Mazda 6 I just bought right now.
