Installed these on my 2005 Holden Caprice (235/45/17) and I'm simply stunned at how quiet these tyres are, how smooth the ride is and how well they grip in all conditions. Usually these tyres retail for about $240 per tyre but Bob Jane did them for $170 each plus alignment, great bargain!

I have a Holden Statesman Series 2 (2001 Model) that originally had Bridgestone tyres that were awful, I then had a set of Dunlop MAXXS and they gave me 15000kms and were as noisy as a truck tyre. I am on my second set of Michelin PS3's and have been astounded by their safety, roadholding and quietness on this heavy car. For me they are the perfect tyre.
Long wearing, quiet, great in the wet, impecable in the dry. Confidence boosting performance
Nothing

Better than Bridgestone Potenza in the dry and easily the best tires I've had for wet conditions. My Honda Integra has never held onto a corner better. The PS3's are quiet, look nice and functional. Will be taking these tyres onto a track sometime soon and will write another review then.
Sporty, Handles great, Quiet, Not overly expensive.
Not the cheapest but not expensive

Have had a set on my Commodore for 18 months now, and I do a lot of driving in my job. They have given me 45000 km of driving pleasure. Using the hand free is even improved with these tyres due to the minimal road noise, even on coarse chip surfaces. Car getting serviced today and they said the PS3's are almost due to be replaced so had no hesitation in approving another set to go on.
Grip, Quiet, Wet Weather Braking
Many people are saying price, at $250 per tyre I have found them to be middle of the road.

I have a set of Michelin Pilot Sport 3 on a Holden Commodore SV6. Originally, I bought them for the front as the old tyres had worn. As our rear tyres started to wear the wife bought a set of Dunlop SP Sport 3000 and had them fitted to the front (thus rotating the Michelin's to the rear). Unfortunately, the Dunlops worn well but badly when compared to the Michelins. Now all tyres are due for replacement as the Michelins have just reached minimum tread depth; twice the tyre life of the old Dunlops. Michelin, here we go again - great tyre, even wear with minimal road noise with no noticeable early degradation.

Just completed the first 500 kms on these tyres since fitment.. These have transformed the Hatch. The plush ride is outstanding for a sport tyre. It's quiet and the steering is brilliant. No push from the front through fast sweeping turns, just precise turn in. Such a compliant sport tyre with no harshness at all. Congratulations Michelin for developing such a perfect tyre that works beautifully with the Corolla suspension.

It is the best tyres I have ever had! The tyres are especially good in wet conditions and they are very quite. They may be expensive, but the are definitely worth it. I bought the tyres in my local Tyreplus dealership. I had Bridgestone tyres before, but these Michelin tyres are much better.

I'm now using the 2nd set on my car and the have 1st set on my wife car fitted recently. With these tires, you can relax driving during the rain or over wet roads and don't have to think about "Aqua planning", because these tires take it so easily. I definitely buy it again. With the 1st set on my car, I got about 60k km out of it. It's also quieter than the original Bridgestone. The size is: 205x55R16.
Good handling, grip, especially in the wet condition.
Expensive

Excellent tyre. I run them on my VY SS and my wifes nissan Almera. They may be expensive, but the are definately worth it. Grip and handling in the wet is amazing. I will not buy any other tyre after having these. Pirellis where my last tyres and although they where good, I dont feel that they are any where near the pilot sports for hadling in the wet.
Grip, quite.
Expensive.

Brilliant tyre! Smooth, extremely quiet and incredible grip. On my Mercedes CLK 320 (235 40 18). Great car but these tyres make it even greater. I also love the look of the tyre. There was some concern in other reviews about the slightly rounded sidewall. Worrying g about nothing! The tyre looks great and sporty.

Well done Michelin. Must admit, I was cynical in the past about these big brands. These are well worth the money. Only problem is I ordered these tyres in November 2012 and only received them two weeks ago (feb 2013). Well worth the wait though.
Quietness, grip and smoothness.

Bought a set (4) of these tyres just before Xmas last year,went away up the coast from Sydney found them to be great,we had all sorts of weather from hot sun to pouring rain the Pilot Sport 3 didn't miss a beat they stuck like glue & there ride is very quiet. EXCELLENT TYRE.
Awesome Grip Wet or Dry - Very Quiet to Drive On

Done 44000 klms so far with 5000 or so to go, awesome grip wet and dry and very quiet. Can't say a bad word about them. With my work i see a lot of road accidents, often in the wet due to cheap or bald tyres. Pay a bit more and buy decent tyres, for your own safety. On a MY08 WRX 235/40/18 42psi front 39psi back. I will happily buy these tyres again!
Everything worth the $!

After reading what seemed like every tyre review on the net to research what tyres to buy for 205/50/R16, I finally decided on Michelin Pilot Sport 3 due to reviews and high test scores on wet braking and cornering. They have transformed the handling of the car and I'm pleased with the quiet ride. I'm hopeful that they'll also be long wearing. After forking out $1000 for 4 tyres I can say I am greatly relieved that they are as good as I hoped for!
They feel safe and are quiet.
Expensive (quoted between 250-300 each).

I have left two reviews for this tyre under "Michelin Pilot Sport" - one when I first got them and one now that they're worn. I did not include the "3" in the original review so it has not shown up with these comments where it should be. Search again by typing "Michelin Pilot Sport" in the box above and you will be able to see what I loved about the PP3.

My friends also have these tyres on their gorgeous BMW M6 coupe (super wide 19 inch), and NO complaints.
Grippy from start to finish, extremely comfy ride when new, wet/dry handling and grip not compromising AT ALL, excellent braking, fast... er 'spirited' cornering
Pricey, fuel econ was up for the first 25,000km, otherwise fantastic and just what is expected of Michelin
