Do I really lose much if I run all-season tires in the summer?

My rear P-Zeros need replacing real soon.....and I just am done with those overall (due to them kicking up rocks and chipping the sh*t out of my fenders). I would have never put them on had I known they were going to be that bad.

I run the Michelin Pilot Sport A/S 3's in the winter. Would I lose much performance-wise in terms of handling/grip if I run those in the summer, too? I know they won't be as grippy as the P-Zeros.....but will there really be a noticeable difference if I am not tracking the car?

I think that in the summer the grip is going to be really bad - regarding the power of the car - and they will rear out pretty fast.

You should put Michelin Pilot Sport 4S, they're amazing.

On my F80 I'm running Conti DWS 06. It's noticeably less grip than the summer pilots. That said I don't drive as aggressive as I used to.

It's acceptable for normal driving. I do see the light kick in above 60 mph depending how hard I'm driving

All season tires are perfectly fine for the summer. You might notice a little less grip during spirited driving, but for the average driver (and when I say average driver, I mean driver not taking the car to the track) you really won't notice a difference. Just don't go crazy, but then where's the fun in that?

I have been running all season for at least 10 months, car is just fine
yes I noticed minimal difference in the grip , but no issues at all
to notice a difference , you probably have to push the car to the limit which most likely few people do anyway
having said that
if I live in a no snow/cold climate , I will stick to summer tires

Oh, for sure......but I am sure it will be snowing here in 2 months.

3s are better rated for tread and wet driving but 4s is better for dry conditions. 3s is cheaper. P zeros are still considered a higher quality tire for grip then either aforementioned.

Clearly if you use non super summer tires, you will void your warrantee......

LOL

All Seasons are fine. If you push a hard corner you will notice it in the extremes.

For example if you have not yet felt "Loss of steering wheel input" on a curve before (I.E. at the point of about to loose grip) then such a feeling will occur sooner. Did this test with '97 M3 with summer vs snows and when you feel it you will know it. The M5's AWD will make up for the loss of some grip, but if you put the car in Two Wheel Drive the difference will be much more pronounced.

Lot's of RS6 folks swapped to All Seasons without a real issue, but all could tell the difference in the extreme driving...I had snows on mine for 4 months out of the year and that car always had grip, you'd feel the softer tires in turns but grip was always there.

I suspect the same with the M5. In winter I have been using Pirelli's and I have not had any issues when the roads are dry and the spirit is willing. Nor any trouble in the snow. I haven to yet developed the confidence in winter driving I had with the RS6, but I have only had this for two winters. I drove the RS6 for 15 years.

You'll notice 20-30% handling loss on dry summer days especially in the curves, on the wet road AS/3 will have better grip.
I wouldn't recommend them for winter.
They are much more quiet compare to P-zeros for some reason.

Just depends on how hard you drive. You drive within the All-season's grip threshold, and you won't notice any difference at all.

You drive to where the summer tires squeal now? The rear will step out and try to swap places with the front. It's just the way of traction.
