Installed Michelin Pilot Sport All Season 4 21" tires on Taycan 4S -- my review & results

[jasonh]

Still liking these tires? How do you find them now since you have some driving time behind you?

Loving these tires. Updated my initial post to include my thoughts. I would happily buy them again.

I've been trying (unsuccessfully) to find these tires. No one seems to carry the rear size you used, except for maybe a 1 week period during which they were available on tirerack. The issue at that time was the rears were only available with "full velvet sidewall" or something (different style basically) but the fronts were not available with full velvet. I did not want mismatched tires (even if only from a design standpoint). Extremely jealous you were able to find these tires ?

I'm STILL quite happy with my choice. They behave well in the wet and cold, no noticeable change in range, and reasonably quiet. Wearing well too.

I'm still on my PS4s that I installed at 8941 milles 11/6/23.
I currently have 17607 miles, so I've put 8666 on them.

So far the tread depth looks great, though I haven't measured. I am pretty happy with them and I got used to the difference in road noise from the P-Zeros quickly.

I'm on the fence on what I will replace them with when I need to; my experience with P-Zeros is they are very prone to picking up nails/bolts when new, and I'm in a house situation where towing a car out of the garage up my steep driveway would be a non-starter.

Immediately after purchasing our 2024 iX M60 (which weights 5,700 pounds without passengers or any cargo), out went the stock Bridgeston Alenza summer tires and we put on Michelin PS4 A/S tires. So much better handling — especially in the wet. As to range, the iX remains a range monster though best estimate we lost about 6 miles per charge (our full charges at home are to 75%).

I did not like the PS4AS on my car compared to the summer Pirellis so I swapped them out with PS4S and am very happy with them. Will put on a set of All Season tires for the 3 months of the year that I need them in TX and put up with the degraded performance during that time.

Derek, Did you find the Michelins to be quieter or noisier than the Pirelli’s?

Noisier than pirellis but quieter than contis. Wear better than both.

Do you have regular glass or double pane (as Michelin’s have always been my go to)? Asking because unless Hankook Ion’s are available when I need them, I would like to get Michelin’s — that is unless someone comes up with a better time in the interim.

I have the noise/thermal glass.

Jasonh thank you…. Purchased the Michelins for my Tycan Turbo and very happy with the performance ……. Now waiting for the Chicago winter ?

I’m about to make this switch as well from the stock Goodyear Asymetrics on my recently purchased 22 Turbo S.

Has anyone considered matching the M01 315/30/21 Rears with M01 275/35/31? Or alternately matching the 265/35/21 with the Y Speed rated 295/35/21? Guess I’m trying to match the 4 tires for same Speed Rating and SideWall design if possible.

I ordered the ND0 275/35 front and 325/30 rear - Panamera tires. Sizes differ slightly more from stock but there was a Taycan Turbo S performance kit they sold in Germany with that tire size so it should fit.

I also wanted matching front and rear, and the ND0 was a plus since the Panamera is similar in weight and intended usage. M01 (Mercedes OEM) were a little closer but sold out at Tire Rack and I felt Porsche variants might be tuned a bit better for what I liked than Mercedes.

They go onto the car next week, I will post both fit and driving impressions.

That would be great to hear your feedback on this. The 305s look so wide already and the 325 on the rear looked huge on the Cayenne Sport loaner I got were massive. I’d be a little worried how Rear Wheel Steering is affected by this with Delta from stock.

The Price delta on the NDO version put me off a bit as well. Paying the Porsche premium but doubt there’s anything drastically different from that version to the General Market Y rated Michelins. Tirerack stock does seem very poor these days.

If Porsche hadn’t offered that size, and used it for the Turbo S Nurburgring lap record, I would be more worried but happy to report back.

Fwiw I think the M01 275/35 and 315/30 are very reasonable/should work fine and I might have ordered them if I wasn’t planning on a Tahoe trip over Thanksgiving that made the back order status a problem.

I also considered the 295/35 rear tires. However with a 29.1 inch diameter I would definitely not pair them with 265/35 on the front. Had I gone with the 295/35 in the rear I would have used 255/40 in the front that are 29 inch diameter. This is very similar to the 245/40 and 285/35 on the 21 inch aero rims and should be fine. Narrower may also slightly improve snow traction.

If the car (including traction control, ABS etc) is expecting the front and rear tires to have almost the exact same diameter, I would keep it within 1% (0.3 inches) at the very most, and some say 0.7% (0.2 inches). Those types of differences in diameter are similar to the differences between front and rear in stock fitments, or the differences that can arise through unequal tire wear so I don’t expect they would create a problem. 29.1 vs 28.3 - 3% and nearly an inch - is much larger than what the car would likely be designed to accommodate and I would be very worried about those systems not working well.

Increasing both front and rear diameters by a similar amount will make speedometer/odometer readings a bit inaccurate but not badly so and shouldn’t effect the control systems in the vehicle (says a guy who doesn’t actually design those systems and is only making educated guesses about how they work…).
