MYP 21' Michelin Pilot AS4 Sizing

[janjablonski]

Toying with the idea of ordering a MYP and doing some due diligence before I pull the trigger. From what I've read on here, it appears one of the best All-Season tire options to swap with the stock Uberturbines w/ Pirelli Summer Tires (I live in a cold/snowy winter area) are the Michelin Pilot AS/4? Thinking of purchasing these and swapping them with the stock tires not long after delivery and before the winter hits. Seems like the easiest, most cost effective option as opposed to buying and storing an entire winter tire set.

I'm a total tire noob, so hoping someone can confirm that these are the correct tires/sizes (if I'm trying to match stock) and that it is as simple as taking it to a tire shop and having them swap them out with the stock wheels.

Thanks in advance

OEM front tire size is 255/35/21. A good alternative is 265/35/21. Actually brings overall diameter closer to the stock rear tire.
Good luck. MYP is great car.

Appreciate the reply. Would I be able to put the 265/35/21 tire on the uberturbine wheel?

Plenty of feedback regarding these specific tires here. I plan on going with OP's tires sizes mentioned in the first post. Michelin Pilot Sport All Season 4 on Uberturbines- 265/35 & 275/35R21

Yes. I confirmed this sizing recently with a tech at my local Tesla service center. No issues at all with 265/35-21. The a/s 4 is an awesome tire.

I just had the AS4s installed on my MYP today and they are great so far!

265/35R21 up front and 275/35R21s in the rear

Planning to keep an eye on the Wh/mi to see how these tires compare to the efficiency of the stock Pirellis.

@ERAUGrad04 Please let us all know what you conclude, noise level wise and efficiency wise. How's the comfort level of the ride?

Why the quick change of tires? You haven't had the car for very long?

Mines 13k miles my rears already bald. MYP as well. I am going 265 fronts as well since the 255 are in pre production.

My stock Pirellis only lasted 14k miles too... After what felt like lots of research, I swapped both the wheels and tires to martian 20x9.5 with 275/40/20 on all corners

So far, they are great! I’ve put about 400mi on them and would say they are are great alternative to the P Zeros.

In terms of noise, I would say they are really close to the stock tires. Measured on my Apple Watch at 68mph on the same stretch of road, I’m seeing about 1dB higher on the Michelins (63-64dB vs 62-63dB).

Efficiency will take some time for a good comparison. I reset one of the trip meters so that I can compare after ~1800mi. The stock P Zeros after 1800mi were at 287wh/mi. So far, after 400mi of driving, the Michelins are at 302wh/mi, however, the driving has not been identical. I’ll be sure to report back after 1000mi+ with a better average.

Had the car only a month or so, however, I will be using the car to head up to Tahoe this winter for some skiing and the stock P Zeros won’t do so well for those trips. A friend offered to buy the take-off stock tires, so I figured I’d make the swap a few months early!

I considered having a second set of wheels and tires, but in the end, not having to swap wheels was the easy button!

Did you buy the Tesla chains for the ubertine wheels? What are you going to do when it dumps snow? This is my dilemma now as I want to take my Y to the snow but my 21s are making me consider getting a second set of wheels.

I got a second set of wheels - a “take-off” complete set of Geminis off of a new LR from another TMC member.

No chains. The AWD on the Y is incredible. With solid AS tires, it should perform really well.

All that said, I’m not planning to make the drive if the weather is planned to be crap. I drove many winters in Chicago in 2wd vehicles with no chains and did just fine. Figure the AWD paired with good tires should do pretty well.

I put AS4 on my LR Y and didnt notice how much road noise there was until I went back to the stock Contis. I will be putting the same AS4 on my new MYP coming here soon.

Nice! Why the switch from LR to P?

When I got my LR last year I was replacing my model 3. They didn’t have any performance in inventory but a blue LR with trailer. All worked out tho, sold the LR at auction for 8k more than I bought it. Now I get the exact build I want. MSM on white no trailer.

I'm up to 6K miles already and may do this, as well, when the rears go. Any photos??? How has the ride & handling changed, if at all? Any effect on range?

Michelin just released stock F&R sizes for the MYP in their Pilot Sport A/S 4's. Apparently they are also considered "Tesla Originals" (T0) and have the acoustic foam too.
