After 7,300 miles, my impressions are similar to what they were when originally installed. Aside from wider temperature range driving, I expect the major differences will be realized from 20k to 30k miles.

Likes:
On-center feel and stability is very good
Do not follow groves in road
Do not transmit minor road expansion joints into cabin
Quieter than Michelin tires so far
Much better traction in wet and dry weather with temps in 30s
New--I prefer the Bridgestone's sidewall appearance over MPS4S

Dislikes:
Tire reaction to aggressive turn-in is lacking at high speeds when compared to both sets of Michelin summer tires.
Difficult to use on a prepped racing surface (drag strip)
- Spin during launch, but have not tried below 25 psi yet
- Not sure if it's the psi, weight of tire or the tire's harder compound but they seem to cause axel hop (more than other tires) on a prepped drag strip. Axle hop only happens at the drag strip and has not happened on a normal road surface.
I had the bridgestones before switching to PS4S
personally there are perks to both.
-bridstones good
quiet
good for cold temps
tracked well on all surfaces
good for cold weather
-bad
traction is terrible for these cars, I had 295 rears and broke them loose at 60mph.
cornering the car leans more, definitely feel the weight of the car.
in general just not a very sporty tire.
-PS4S good
great grip
Corning grip vastly improved and the car stay much more level.
actually takes bumps better than the bridgestone
-bad
the car doesn't track as well, falls towards the side of the road, with the slope of the road(had an alignmemt done to make sure that there wasn't and issue.)
no good for anything beneath 40 degrees

Iím going to be getting tires here in the next month and I will be driving in temps well under 40, but it only snows maybe once a year. For a daily driven commuter that occasionally hits the mountains Iím leaning towards the Bridgestone tires. Was going 275 front and 305 rear so maybe that would help with traction some.

I wish I could get AS3+ tires in M5 sizes.

Does anyone else have any good 4 season tire suggestions?

I have found the Michelin Pilot 4 All Season and really want them. They were just released and only have two sizes available on tire rack so far.

Was hoping to here a bit more input.

So, what about Michelin Pilot 4 All Season's? There fitted on the C8 Corvette so they have to be pretty decent.

Sadly, sizes are limited right now. I could so 265/40-20 and 305/35-20.

Thoughts? I talked to a guy running those sizes with no issues with PS4S's.

I ended up ordering the Bridgestone RE980AS in 265/35 305/30. Hope I like them, was really hoping the Michelin AS4’s would be released in compatible sizes.
