Michelin Pilot Sport A/S 3+ First Look Review
First let me say thank you to Michelin for giving us the opportunity to test their new Pilot Sport A/S 3+. Our day included open highways, canyon driving, city streets and finally on the track at Spring Mountain Motorsports Ranch about 60 miles outside Las Vegas, Nevada. Three cars made up our testing, a pair of 2015 Lexus IS350 F-Sports, 2015 Audi S4s and 2015 BMW M4s which I drove throughout the day. The focus here was to showcase the increases in wet and dry traction as well as steering response over the original A/S 3 and other competitors in the ultra-high performance all season class. A smaller group also tested the tires enhanced winter traction in Steamboat Springs, Colorado with BMW 335's.

Highway/City/Canyon Roads
We left Las Vegas early morning hitting moderate traffic but eventually met more open roads outside the city leading toward Hoover Dam. The A/S 3+ responded great in/out of traffic and they really felt at home on the twisty roads leading up to our first driver change near the dam. At regular highway speeds the A/S 3+ was very quiet and rode great, even in the M4 with 19's. After swapping cars, we made our way through the foothills of Red Rock Canyon. The tire drove excellent and begged for more driving through the canyon. We ran into some high winds and rain which didn’t affect the tire's performance or ability to hug the curvy roads. We spent a good four or so hours of public road time over the three different cars before heading to the track.
Our next stop was Spring Mountain Motorsports Ranch in Pahrump, Nevada to see how the tire performs when pushed to the max. This is a world class facility with over six miles of track, an 8,000 square foot clubhouse, pool, and even condos. They are also the official high performance driving school of Corvette and offer a two day Radical SR3 racing school. Three exercises were set up for us, a dry/wet auto-x course, dry braking demo, and lead follow on their track. Michelin put the new A/S 3+ up against Continental's Extreme Contact DWS06 and Pirelli P-Zero All Season Plus during testing.
Auto-x
The Lexus IS350's were test cars of choice here. The course featured a combination of offsets, several 90-degree and one 180-degree corner, and a slalom. A combination of dry and wet surfaces, with the middle third of the course being wet, allowed us to test the transition from one condition to the other. It was quite obvious the A/S 3+ was the stronger performer here in steering response and hands down in wet traction. The transition from dry to wet was at the exit of a quick 90-degree corner, here the A/S 3+ displayed the smallest difference in traction as it crossed the transition. Overall, for an all season tire being tested in an auto-x environment I was very impressed.
Dry Braking
In this exercise we used the Audi S4's to demonstrate 60 - 0 mph stopping distances with the anti-lock brakes fully engaged going into the braking zone. We used an onboard data logger to measure and record the distances each brand of tire required to stop. A similar test is performed at our headquarters in South Bend and we typically find there's minimal differences between the tires. The same type of results were found in this exercise. After 40 panic stops made on each tire the AS 3+ showed a small shorter distance advantage over the other two in dry braking.
Lead Follow
They weren’t quite ready to cut us loose alone on the track with a $70K+ M4, but we did get a lead follow session in. Keeping in the back of my mind I'm track driving an all season tire, I was still quite pleased with how well the tire performed. Larger outer shoulder blocks helped plant the car confidently through the corners and response back to center after a turn was snappy. Great dry stopping allowed me to brake a bit later and provide more power out of and through corners. Like other all seasons, it's not a tire I'd try to win a SCCA championship on. However, for the purpose of demonstrating how the A/S 3+ feels outside its comfort zone I was impressed.
Snow Testing
The other crew started their snow testing with an acceleration exercise starting from a dead stop to just over 20 mph. Same data loggers were used, traction control was disabled, and the same Conti DWS06 and Pirelli P-Zero All Season Plus tires were tossed in the mix. The data logger measured the time it took to accelerate from 5-20 mph over six runs with a final run on the first tire. The Michelin and Continental performed very similar with some members having a faster 5-20 mph on the A/S 3+ . Their next test was braking from 20 mph to a full ABS stop. The data loggers measured 20-5 mph stopping distance with, the Michelin averaging a few feet shorter than the Continental. The Pirelli couldn't keep up with the pack in these tests. What's important here is how much better the new A/S 3+ is in the snow compared to its predecessor, the A/S 3, because of the compound change. Those who have long term tested the tire here during our Midwest winter have also expressed how impressed they are with the snow/ice traction.
Conclusion
Michelin reinvented their position in the Ultra High Performance class with the new A/S 3+ . The enhanced wet traction, steering response, and much improved ice/snow traction has made them more well-rounded than the original A/S 3. It's an enjoyable tire for spirited driving on curvy roads, yet on long hauls it delivers a great ride with minimal noise. You can drive this tire more confidently in snow and ice, and those who see more rain than snow in their area will be impressed with the hydroplaning resistance. Michelin knew the original A/S 3 fell just short of the bulls eye they'd hoped for. However, working up from that base and changing a few things (most importantly the tread compound) has made the A/S 3+ a top contender in its class.

Got a set right before last winter. Didn't drive the car in the snow but the performance in dry, cold and in wet conditions is great. Very good grip, ride quality and a quiet ride.
I had the pleasure testing the wet performance while driving back in a torrential downpour on the highway. Not once did I feel a lack of grip while driving the posted 60 mph. By the way I thought I was going much slower for the road conditions. I will keep this as my wintertime setup even after I get some new wheels and tires. Michelin of course!

Nice post and quality content to read for a change. It's simply fascinating to see how tire technology continues to evolve. Not so long ago, an all-season tire that could withstand being torn apart on the racetrack, while still providing some traction in sub-zero temperatures was pure science fiction. Tire compounding remains a black science to me, but we all enjoy the results.
