Whilst I still default to my preferred Mchelin Pilot Sport 4S for my next set of tires (XL rating etc will work), I do pause everytime I read or view more info on EV specific tires. Michelin make a Pilot Sport EV (in widths of 265 and a 295, but no 305) that would work with my 21" wheels but offer only a 20K warranty vs 40K with the conventional 4S variants, which is interesting even allowing for added thread wear. In a recent online availabiity check though it was easier to order the 4S's as the 295 EV's were out of stock/hard to find. Still pondering but will have to get off the fence fairly soon.

I cant find anywhere to actually buy these tires. I’m due and am looking hard at these, even tho i have very much liked my Pilot Sport 4S tires.

Treadwear warranty is cut in half if you have a staggered set up for the rears.

Split Fitments
Some vehicles come from the vehicle manufacturer with “split fitments” – meaning different sizes of tires on the front and rear axles. Because these tires cannot be rotated as recommended by Michelin, the mileage warranty on each rear tire will cover half
the number of miles as the standard mileage warranty for that particular tire design.

I was amazed when I got 20k it of my PS 4s.
I did not use on the track, bit loads of late night cross country journeys and they never let me down. Only started to go off at 19500.
New 4SCT has non sport 4s and although they are markedly quieter, they just don’t give as much confidence.
Would be happy to look at an alternative, but it’s an expensive experiment if they don’t work out.

Is the 40k warranty offered also for an EV application? I suspect not, and so that tread wear might really add up to the difference.

(This, btw, also made me wonder whether the forum participants reporting excessive tire wear on their Taycans were really using EV-rated tires or not.)

I did not see nor read any qualifier in respect drivetrain type for the Pilot Sport 4S tires being sold on TireRack that either negated nor reduced the posted warranty (can recheck though) - the load rating for the std tire fits the weight of our Taycan's so at a basic level there does not seem to be any hit on warranty if you put std 4s's on your car - others have purchased these so if they have been told otherwise it would be good to know.

On the other hand, I have NEVER exceeded 20K wear on all the 4S sets I've owned (at least 5!) so TBH wouldn't bother me regardless.

I have never put much weight on wear warranty, nor the N- or other manufacturer specifications on tires. Consequently, I dismissed EV-specific tires as yet another point of profit. However, the one aspect I hadn't considered until watching the video at the bottom of this thread was the stiffened sidewall and, again, I suspect a softer-sided tire would squirm more - and thus wear out faster - on a heavier car, especially one with a lower CG (that encourages/tolerates more aggressive cornering).

As an aside, run-flats also featured stiffer sidewalls, and I really, really hated those on various BMWs.

Agreed and same feeling but suspect the EV specific side wall construction combined with other features of the EV specific tire likely provide a better over all ride than the original stiff walled run flats - I say this as having 6000 miles on my EV specific Pirelli tires I can say definitively they are far better than the run flats I experienced of old! All this of course discussed in older threads here too.

At this point the differentiator (if I could find the Michelin Pilot Sport EV front+rear set) would come down to the quieter ride vs the std 4S's - the lack of availability however there and the potential to be stuck with a 295 with a shallower side wall than a 305, means I will instead end up getting the 4S's !

I was just checking Porsche online configurator (Portugal) and apparently the 3 tire brands they are suggesting are Continental, Michelin and Hankook when you click on the tire spec.

Based on that, avalability (Can't find Michelin Pilot Sport EV in 305 anywhere), some research and the video above, I'm putting Hankook iON tires on my 21'' when I get my car. Can't wait to test those.

Just to repeat from above, I had asked Michelin directly re them ever planning to make a 305 EV tire and they have no plans as yet - so not an option as yet only 295.

Hmm. They do list it on their website. Maybe it's a "future" option if there's demand or something.
