Had planned to wait till next year to replace my MPSS with AS/3+, still have about 2mm left to the wear bars. This week I picked up a nail in a rear tire. No big deal - but turns out to be in the same tire I had patched in the first month of ownership. They won't patch the same tire twice here. So I plugged it myself while I wait for the AS/3+ to arrive at Discount Tire next week (rears are shipping from Georgia I think). $1,363 out the door - pretty happy with that.

C7X46,
Okay, I promised that after I had my A/S 3+s installed, I would provide my impression. I had them installed a week ago but have only driven it a mere 50 miles, so I was waiting to log some more before providing my impression. That may be a while, so I offer this preliminary impression.
Noise level: Maybe 10 to 15 percent quieter but still rather loud.
Dry handling: Massive difference but please take into account the fact that I've only driven the car 50 miles, so the "nubbies" are still present. My guess would be that cornering capability is reduced by 30 to 40 percent but I have to assume that will improve somewhat but will never be even close to the MPSSs.
Wet handling: I have no idea, as I have yet to drive in the rain. That said, comparing the tread of the two tires, wet traction has to be improved dramatically.
Steering response: Dramatically slower than the MPSSs . . . but they should be given that the tread compounds are drastically different. The A/S 3+s appear to have a "standard street tire" compound with the tread depth, (10/32" on fronts and rears), being nearly 30 percent deeper. My guess is that the sidewalls of the A/S 3+s are much more compliant than the MPSSs. All of that would increase the flexibility of the tire.
Braking: Don't know yet as I have yet to drive the car "in anger" with the A/S 3+s. My guess is that braking distance will increase considerably.
One should not expect the A/S 3+s to be a track tire. I bought them to extend my driving season, and I have no doubt that they'll do that, if for no other reason that they can be driven at freezing temperatures which should absolutely not be done with the MPSSs. Ya can't have it all, folks!
Most importantly, yes, were I to do it again, I would buy these tires as they increase my driving season by 70 to 80 percent and that's why I bought this car!
I'll update this when I've put on five hundred or so miles.

Have you logged enough additional miles since this post to provide additional information regarding these tires? I may wait it out until next fall as it is turning cold here now and I only have 8K on these tires and I should be able to get another summer driving season with them.

I installed the AS3 about two weeks ago and logged about 400 miles so far. I live in Colorado so I was looking for a tire that could hold up in temp below 60. I can say that the transaction is night and day difference from the cup tires. Inside the car it is quiet as can be as well. I am a huge fan of the AS3 already.

I installed the AS3+ last week on a second set of OEM wheels and feel the only compromise is steering input. The AS3 require more steering input however, I am comparing them to PSS with 10K miles on them so a large portion of that change could be attributed to tread squirm of the new tires. When you first install them they will feel disappointing for the first 250 miles but then really start to come to life, possibly the mold release compound scrubbing off the tires. The increased steering input could most likely be dialed out with a more aggressive front alignment setting and will most certainly improve with wear, I wish I could compare them to new PSS for a more accurate comparison. The AS3 hooks power from a start better than PSS at or below 70F and I can only imagine that advantage is more pronounced as temps drop. I bought these to increase driving season of the car and feel they will do that no problem. The PSS were downright dangerous in temps below 60F and break loose violently when they go, and yes, I have corrected the camber and alignment on my car. I want to stress to those on the fence that review from the initial install of these tires should be taken lightly as they dramatically improve with a few hundred miles on them. I'll do a mountain drive this weekend in 40-50F temps and report back next week, so far I am very pleased with my purchase.

Had mine installed yesterday. Obviously very new but it is rainy and in the 50-60's. I can tell you this....you can actually put more power to the ground without puckering each time.
We'll see how they handle in the dry and I get some miles on them to let them settle in.

These tires are incredible. I can actually put the hammer down in the cold now. Rain performance is night and day better than the OEM non-cup tires as well. I will not buy another set of OEM tires due to the middle tread block issue anyway, but I hope I can get away with running these new all seasons year round for street tires.

From the Michelin wen site they only guarantee 15 miles if you cannot rotate all four like my C7 is 18 on the front 19 rear 15,000 is it can maybe adjusting tow help

I completely agree. No real difference in noise levels on a decent asphalt road, but major difference Vs PSS ZP on a concrete freeway, the drone on the concrete is much reduced.

Well then we must be driving differently. Even the MPSS I did not track only lasted about 8k miles. How much tread depth do you have left at 12k miles? Mind taking a pic of the rears so I can see how your inner tread block looks? Maybe they actually hold up if you are really easy on the tires.

Have you done an alignment check on them? I've read quite a few people getting well over 10k on the MPSS tires if they weren't hard on them. If you're getting lots of inner tire wear, it's very possible the very wide range of factory alignments could have been off and at times it's seemed that the plant is putting a fairly aggressive and more track oriented alignment on many of them. Quite a few people that didn't get it checked early on have complained about tires being worn out around 8k...down into the cords even. I'm curious as I'm waiting on mine now! Hopefully longer than 8k and I definitely plan on having the DSC street/occasional HPDE alignment settings put on the car, which I'm told give you pretty good life on the tires.
What is " DSC street/occasional HPDE alignment settings" I'd like to know what that's all about.

I have the AS-3. Just a note, The AS-3 comes in various versions based on whether its a 98Y or a 94Y. The one you want is the AS-3 with 94Y performance.
