Put Panamera Spec Michelin Pilot Sport S 5 on Taycan

[StellarOats]

Wanted to try the upgrade to the PS4S and they only make it in Panamera size (275/35/21 and 325/30/21 ND0).

Wanted to say they fit great on stock 21" wheels with stock offset, no spacer needed with no rubbing which I couldn't find clear answers on. The rear seems like it has lots of room, but the fronts are very tight to the upright and maybe will scrub under super heavy lateral load, not sure yet. Will report back on how many lateral g I pull as soon as I do an Angeles Crest run. Was getting 1.14 to 1.17 peaks from car in right turn and 1.07 on left turns (mainly as I am unwilling to press my luck on turns that lead into a rock or off a cliff, not that it wasn't capable of being equal) on the in car g-meter on the PS4S and Pirelli's when hot in stock size (265, 305). I don't anticipate these doing much better but welcome maybe 1.2 out of it when hot. On the road they drive very nice with much better tracking over rough road joints than the pirellis had which caused the car to wander. I really can't tell any other difference yet other than I fully expect the larger size to further decrease range.

Mainly wanted to share that this size fits easy although front's are tight.

Nice! Have pics?

I find my Michelins get very noisy as they wear....I would love to find a quieter summer performance tire

 

[StellarOats]

I'll get photos up soon, and so far I really haven't noticed tire noise differences, but I tend to play the radio loud so I'm not the best judge.

One other thing to mention. The extra width and the deep lip on the PSS5 gives great curb protection to the rim. Far better than any other tire I've had on the car.

I did the same on my stock 21” wheels along with 15mm spacers and usually drive around in the lowest suspension setting. I think it’s perfect, the tires are really great and I echo the feelings of the Original Poster.

Here are some quick pics for further reference beyond what @StellarOats has already provided.

325 in the rear? did you get a new alignment? same rims?

Stock Porsche wheels.
Panamera runs the tires on stock wheels of the same size on their hybrid models.

I had just done an alignment on my previous set of tires which I swapped out at 8k miles and so I did not do another alignment as everything was running true and straight.

the overall wheel diameter of this set and the original set of tires is minimally changed and is within acceptable parameters as to not cause any computer issues or any meaningful detriment to handling or steering dynamics. If anything, it has improved.

Yeah, i just put the tires on stock wheels (although my wheels are from a CT taycan as I traded with another forum member for my aeros, but they are same size/offset as any 21” taycan wheel)

I did not do spacers and the front is tight to upright with maybe a cm of spacing. The rear seems far from everything as best i can tell with feeling around blindly.

The rear could hold a 345 in my opinion but dont think a aspect ratio exists to keep the tires matched front/back on circumference. The front cant take much wider. While a spacer will fix the distance to the upright, at full lock the edge of the wheel is basically touching inner fender liner at edge of the tire. I cant hear any rub doing anything, even turning at full lock, but i dont think you could get a 295 width in there without being willing to have it rub.

I may try 295s in front for my track wheels and report back since I can always just not turn hard on them and they will wear out fast enough I don’t have to live with a mistake for long.

i'm running RE71RS 285/35r20 all around for the track. better than ps4s and much better than pzero pz4. if i only did 1-2 track days a year, i think the pss5 on 21" would be sufficient.

@StellarOats was the range affected significantly? 305 to 325 is a big jump

 

[StellarOats]

I cannot tell a difference given the way I drive the car. The car thinks the range is roughly the same, but I never really go drive long distances in a steady manner to get a real baseline. I can't see how adding a half inch up front and a inch in the back isn't bad for range though, but I wouldn't notice 10 miles out of 200 the way I drive it.

User jay bullington over on FB made some suspension parts for the taycan and is running 315 up front. Thought you guys might be interested since you like to track your car.
