I just put a set of Michelin Pilot Sport A/S 3+ on my 2014 Impala 2LTZ. These are Ultra High Performance tires and so far, I love them, they will probably not be great with snow, but I have read that they will be better than the Goodyear RS-A2's that I had. A better balance of all season would be the Michelin Primacy MXM4 or the Michelin Premier A/S, but they cost more.

The Continental Extreme Contact DWS 06 are supposed to be pretty good including snow. Others have said the Pirelli Cinturato P7 All Season Tires are pretty good. The Cooper CS5 Ultra Touring might be a good choice as well.

Just remember that All Season Tires in general are a compromise, none as good as a snow tire or a summer tire.

Just put a set of 235/50R18 Michelin Pilot Sport A/S 3+ 97Y tires on the SS. The W rated tires would do just fine but the Y tires were in stock. They're quiet, hang onto the corners, and don't hydroplane on light mist. Winter is not as good as summer but these aren't snow tires.

The Bridgestone Blizzak WS80 or Nokian Hakkapeliitta R2 are excellent snow tires.
I've run Bridgestones as year-round tires on a pickup. They are noisier than all season tires but traction was not a problem. The summer traction ratings on Tire Rack are almost as good as the Michelins but snow tires wear faster in the summer. The Bridgestones were only good for two winters and summers starting new in late fall. If you want tires that are very good in all seasons, and don't care about the fact that you'll likely only get 20-30K out of em, I'd get a set of the Blizzaks or Nokians in the late fall and drive em for two full years.

Good riddance to the BadYear Eagles GM installed originally on my Impala... Yes, I drove it way too long on the original 2009 tires. They should've been rolled into the dumpster in 2016. Only had 28,000 miles on em.

I ran the original Continental tires on my 2005 VW Jetta TDI till they failed. I can't recommend them. Delamination in the sidewalls at under 15,000 miles. The TDI is hardly a sporty car... never saw 85mph in that rig.

I'm running BF Goodrich Radial T/A 215/65R15 White Letter tires on new American Racing VN47 15x7 wheels on the 1985 AMC Eagle Sport Wagon I just bought. Traction is pretty decent but this won't be run in the winter and I'll try to avoid rain. I bought these more for looks on my toy.

My Mom runs snows year round on her Acadia, they live in a place that sees 180" average annual snowfall and she doesn't put on many miles, most weeks just 40-50miles, she would never wear out tires like that but they do take it on some road trips. If she tried to swap tires seasonally she would have dry rotted tires with half the tread left. Tires are often shot by 4yo regardless of tread level, I would keep that in mind when looking at tread wear warranty and such.

On economy, OEM tires are often about as good as it gets because with CAFE that matters, a tire designed to be a better tire vs. be best a fuel economy is likely to give up some fuel economy. On my wife's 7th gen she saw a 10% hit going from OEM tigerpaws which were garbage then(it all changes over the years) to the GoodYear Assurance. Seems like modern tires don't give up as much but you still do see some difference.

I'd buy the CAFE WAG if the Michelins weren't showing @2mpg gain on the first five tanks with zero other changes. I've been keeping mileage logs since she was new. Went from @ 23mpg to @ 25mpg.
The same mix of rural 55mph two-lane highway NH-25 and I-93 from Plymouth to Tilton at 70mph using 91 octane E0 gasoline that I was doing on the Eagles for the last year. AFM is still on and I'm running in 4cyl mode a lot. No in-town miles... Not much town up here.

I didn't expect to gain MPG. Just the opposite. The Michelin Pilots are supposed to have more traction and they appear to have better grip on tight entrance and exit ramps and certainly do in the rain. Better mileage is counterintuitive.

Looking at the data... The mileage with the Eagles were fairly consistent over their life.
I'd like to run at least 15 more tanks of fuel before I say this increase is not an outlier.

One of the tools I use when buying tires......

I am not trying to promote TireRack.com over any other Tire merchant just showing you the comparison list they have on their site. Might help someone make a decision on the the brand and type of tire to purchase for your needs. Hope it helps.

And you can see where the Michelin AS3 tires are rated... :devil
Worth every penny.
