Have put a little over 700 miles on them, actually finding reasons to drive out even during these funny times to test the tires under different conditions (mainly cold and wet weather). Tires were road-force balanced by best tire shop in the area. No suspension alignment done yet as I will be doing that soon after MPP adjustable coilovers and camber arms are installed; original tires wore and drove well so I don't suspect bad factory alignment.
For perspective, I've had several top-reviewed (on tirerack, for their time) non-OEM tires on other cars, each purchase influenced by the previous one:
Mazda 5 (from factory all-season Yokohamas):
- to Pirelli Cinturato P7 All Season: less noise, incredible low rolling-resistance and improved fuel economy, better light snow traction, worse steering feel, worse dry grip
Mazda RX-8 (from factory summer tires):
- to Goodyear F1 Asymmetric summer tires: better grip, especially in rain, less noise, slightly better ride
- to Michelin Pilot Sport A/S 3: fixed dangerous cold weather issues with summer tires, firm but much better ride, great performance in any weather, great steering feel
Model 3 (from 19" Sport Michelin factory tires):
- to Michelin Pilot Sport A/S 3+: much-improved wet weather grip (essential in rainy northwest, unless I drive like a granny), better breaking performance and grip, great steering feel, somewhat less range, somewhat better ride, tire hum on highway otherwise more silent in city
I still take out the Model 3 with the A/S 3+ for comparison, the A/S 4 is a big improvement in:
- better grip
- not silent but no droning highway hum
- less tire noise overall
- tire construction, sidewall design, and quality is A++
- supposedly consistent grip and noise levels as thread wears down
- supposedly amazing snow performance (not just light snow)
compared to Model Y factory PZero summer tires:
- much better steering feel, incredible confidence on any road / temperature / wet/dry condition; I honestly thought the original set-up with the PZero tires was borderline dangerous on certain less-than-perfect curved roads
- better road manners, less bumpy (honestly at 40-41psi, maybe the MPP suspension is no longer a necessary upgrade for driving my family)
- less steering effort, and this was a big surprise especially with increase to 265mm front tires (my litmus test is my concrete garage; maneuvering in/out of garage with PZero tires was exhausting, made me hate the car)
- there's definitely less noise in all conditions and speeds; the more miles put on the tire, the less noise, and by around 200 miles it was great; when new the rubber was so sticky, I noticed it was picking up so many little rocks in my garage and less-so now.. under 200 miles, that likely negatively impacted range.
- at 700 miles of driving, mainly spirited driving, 70+ on highway, almost always cold and wet conditions, trip computer says 340 Wh/mi; not at all bad, I anticipate better-than-stock numbers in more ideal (and slower driving) conditions; if they perform at a similar Wh/mi than stock (and with the way these tires perform, handle, grip so well in all conditions), that's more than enough as thread wear is significantly better and ultimately saves on car running costs way more than electricity efficiency numbers; if the PZero leads to a crash in cold weather but got 200 Wh/mi avg. driving like a rock, it will not matter.
- wet weather- PZero performed well (incredible full-acceleration grip at 50 deg. heavy rain, in fact) until temps hit below ~40 deg. where it suddenly felt dangerous to drive my family on the highway, was forced to drive slower than traffic and no autopilot to assure safety (PS A/S 4 ordered immediately after); 90% of my driving on these tires has been cold and wet weather, and this tire has been a game-changer for this car; last 2 nights have driven in heavy rain on the highway (we have category 5 atmospheric river now), I have felt slight adjustments to steering from big rain patches on highway, but these tires are very-resistant to hydroplaning and give great confidence in the car's behavior
- grip levels- I've only lost a hint of grip once, which was the 2nd turn out of the tire shop where I hit the throttle; same experience as when I just had A/S 3 installed on my RX-8; what you expect from very new tires .. my hardest grip test for these tires, which is a ~30 deg. uphill stoplight in 40 deg. temps and rain and flooring the throttle as lights turned green (at 85% SOC) had no grip loss whatsoever, just pure, unbelievable acceleration. For comparison the loaner Model S P90D (in ludicrous; I had SC unlock PIN code) I tried on that stoplight (with Michelin Pilot Super Sports) in summer temps with rain had noticeable slip. 40 deg. dry weather grip matches the road grip performance from summer temp PZero tires (and absolutely a big improvement at 40 deg.). Basically, with these tires you'll likely beat anything off the line and in cold rain, it's how badly you want the other guy to rethink his choice of car.
