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

I’m 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 I’m 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.

BAD NEWS: This past week we got 2 inches of snow in Maryland and tires were barely useable. Then, later that same day, we got a good amount of sleet and ice.

The tires were useless in snow with ice on top. I literally had to go up a very minor grade backwards to get home. These tires, when 305 mm wide, are useless in snow with ice and may not be much better at lesser widths.

These tires are much better than summer tires when road was below 40 degrees F and without snow and ice. To drive this vehicle in snow of any kind, it appears it may be best just to make the investment with a dedicated set of smaller and thinner wheels and true winter tires.

Hey man, sorry about no response, try to quote people so they get a notification on their phone or website when on.
And like previously stated by 1320 the tires aren't great for snow but are good in the cold. Unfortunately at 305mm no tire will grip well in the snow. For winter sets of tires with snow in mind its a good idea to stretch the tire to fit. Maybe a 275 or 285mm would work best.
I personally have two sets of tires and just have them swapped between seasons and for the snowy days I switch to my winter beater.

No worries guys. I'm more worried about the cold. Very rarely snows here. I have a Jeep Cherokee 4x4 if it really snows. Tires are great though. Thrashed them in the mountains today with my my friend and his M3 on MP4S's and I can keep up all day long.

Interesting write up 1320! The wear your tires show in the side by side view is identical to what I see on my cars MPSS's and very similar to how my E90 wore tires. Neither cars have ever been in an accident, this is how the suspension is set up by BMW. They have negative camber, some in the extreme-look at the e53! If you hustle the car on winding roads, getting deep into the throttle on corner exit, that inside rear is doing lots of work and wears faster. My rears are about done with a bit over 10k on them.

About two weeks ago, we received a good amount of ice again in Maryland. I needed to run some errands, so instead of using the old Jeep, I wanted to try out the tires again with mainly just ice on the roads. The temperature was in the mid 20s and in these conditions, just ice and no snow, the tires did a better job. Maybe the tread design does not self-clear snow well. I felt the tires were above satisfactory on this trip as I had no issues stopping and going up hills.

1320racer, would be interested in touching base with you. Same things with my 13 M5, quite honestly after 20 months now of ownership I am considering selling. I have owned 3 e39 540is, one a wagon. Miss those babies. I am just up 81 in PA

I'm still really liking these tires. They are wearing slowly so far and looking good. They handle fast twisty stuff at the Dragon very well.

No snow or ice but they've been great in cold temps. I do run boost by gear to try and keep things in check.

Still rocking these tires. Treat tires were at 2/32 at 10k miles but the replacements were about half price for to the tread wear warranty through Discount Tire. Still a ready great tire if you drive a lot.

Tire Impressions for Bridgestone PTZ RE980AS beyond 20K miles

After just over 20K miles, here's how the tires have performed.

Tread Life: FRONT 7/10ths and REAR 4.5 to 5/10ths

Likes:
On-center feel and stability remain excellent
Tires still do not follow groves in the road
Are just beginning to transmit road expansion joints into the cabin
Tire noise on some road surfaces is now present, but still quieter than the Michelin tires
Still maintain better traction in wet and dry weather with temps at and below 30 degrees
Prefer the Bridgestone’s sidewall appearance over MPS4S

Dislikes:
Aggressive turn-in is lacking at high speeds when compared to both sets of Michelin summer tires.
These heavy tires reduce the vehicle's gas mileage
Do not work well on a prepped drag strip
- Spin during launch even when aired down below 25 PSI
- The weight of the tire and the tire's harder compound seems to cause axel hop, more than other tires, on a prepped drag strip. Axle hop only happens at the drag strip.

I'm still loving them. The first set of rears lasted 10k miles. Traction is still impressive. I ran the Dragon in the pouring rain Friday and they stuck great and inspired confidence as always. You can still break them loose in first of course, but that's with pretty much any tire.

FINAL UPDATE of Bridgestone RE980AS tire

FINAL UPDATE:

From 71,XXX to 109,XXX miles

Tread Life: FRONT 3.5 to 4/10ths and REAR (Not Applicable)
My rear tires were unfortunately replaced multiple times due to large punctures by road debris including random pieces of metal and bolts. I am now running on the rear, MichelinPilot Sport All Season 4 at the OEM size (295/30/20). The 305 section width tire option seem to only be available as zero pressure (AKA run-flat) tire. This run-flat tire, is fitted on the C8 Corvette.
Likes:
Fantastic in terms of tread wear
Still do not follow groves in the road
Transmit only major road expansion joints into the cabin
Tire noise on certain road surfaces remain present, but still rather quiet for the tires with over 38k miles
Still maintain good traction in wet and dry weather during cool temperatures
I like the tire’s sidewall appearance

Dislikes:
Aggressive turn-in at high speeds is now compromised when compared to both sets of Michelin summer tires.
These heavy tires are still reducing the vehicle's gas mileage
Independent of being old or new, they never worked well on a prepped drag strip. Here are my findings…
- Best rear tire pressure to launch the car was 27 PSI
- The tire’s hard center cap seems to cause axel hop, more than other tires, on a prepped drag strip. Axle hop only happened at the drag strip, not on normal road surfaces.
