Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

Replaced the old Stock Pilot Super Sports on my ‘19 Z06 Convert with a fresh set of Pilot Sport A/S 4’s. Absolutely love them. Pilot Sport A/S 4’s are rated for hot and cold ambients, dry, rain, and even snow. The perfect tire for northern state roads and highways. The Ackerman effect with tight turns, hydroplaning on rainy roads and pebble showers on the bottom of the car common with Pilot Super Sports is gone. The A/S 4’a are definitely quieter than the Pilot Super Sports. The A/S 4’s may have a bit less traction on hot dry track days but I’ll never miss it. I’d much rather have the extended driving season with the A/S 4’s . Thank you Michelin!

Tire has amazing qualities in which i love. Tread will not keep up the 45,000 miles in which is stated. 255/40/ZR21 & 265/40/ZR21 Are the tire sizes i own. I can not purchase Hazard Insurance due to size of tire, thankfully i have not had an instance which requires it but its good to have. Please create a tire for winter for these sizes. Much appreciated!

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I’ll have to chalk this purchase up as a negative one and will be looking for something else in the near future.

I bought mine for an Audi A6 3.0T Quattro when the car had 52k miles on it. Absolutely loved how they handle on wet and dry roads. However, super disappointed with tread life. I have 81K on them now and one tire is almost completely bald, and the others might have 2/3K left until they look similar. Not an alignment issue either as they were rotated and tread is worn evenly. We swear by Michelin tires, and love the Defenders on our Yukon, which is why I’m being fair with 4 stars. But I will probably consider something else to replace these Pilots for this particular vehicle.

These handle really well and helped me out a lot with the big rain we get in Florida. Unfortunately, 2 tires are down to 3 and 2/32nds. 2 Tires are down to 4.5/32nds. I have about 20k miles on the tires and drive on the highway mostly. Florida roads can be pretty rough since they get baked, so I imagine this is a leading cause. I'm hoping to get some warranty on the 2 tires that are near the end.

Using these on california roads that are chewed up and spit out and they work great. No issues with it wobbling or moving or tracking wrong. Loving life with these. If I had worn struts, shocks, or bushings I would probably have issues on rough roads like other reviewer said. But probably just their car having suspension issues, no way it could be these tires Uneven cut up pavement, rough pavement, patchy road, cut up road, and partial gravel. All no issues so far, two weeks in. Cant wait for winter!

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.

Just had these tires installed on my Kona Urban Edition. (Pilot Sport AS4) I am very pleased with the sporty look of these on my car. Also it was raining pretty hard while driving with these and found them very responsive with very good braking as well. (While following recommended speed limits) Another plus is that they are quiet! Very smooth ride too. Both on Highway and town driving. I feel they grip the road exceptionally well. They should serve me well for my driving needs. Highly recommend.

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.
