Update: Tire replacement research: Primacy MXM4 18" - Costco tires NOW HAVE acoustic tech

Update: Tire replacement research: Primacy MXM4 18" - Costco tires NOW HAVE acoustic tech

Update: I got my 18" tires ordered at Costco today and they now have the stock tires with acoustic tech.

Old info--------

I'm just sharing what I found out today about replacing tires on my Model 3.

I was going to buy replacement tires from Costco since my tires are almost worn out (3/32 @17.5K miles). Costco has a deal going on Michelins $70 off a set of 4 tires and 1cent installation. Everything looked great UNTIL I found out that the part numbers sold at Costco do not come with the Acoustic Tech.

Stock 18" Michelin MXM4 on the Model 3s come with Acoustic Tech ( https://www.michelinman.com/US/en/why-michelin/michelin-acoustic-technol... )

However, there are 4 different manufactures part numbers for Primacy MXM4 tires: 14644, 34445, 70631 and 16144. Of these, only part# 16144 has acoustic technology.

Unless you talk to the representatives at Michelin, there is no easy way to differentiate these tires from their printed specs.

And Costco does not carry 16144 (bummer for me) [Update Costco now has this tire]

Thanks for the heads up on this. This is annoying/confusing.

deezeela | September 10, 2018

Thanks for your research.

httran26 | September 10, 2018

I would just buy it at costco without the acoustic tech. It would be lighter so you will get slightly better range or Wh/mile. The trade off is I would expect slightly more road noise.

hokiegir1 | September 10, 2018

Thanks for the headsup! We were just pricing them out at Costco yesterday for future reference. We'll be sure to confirm when the time comes.

@httran26 "I would just buy it at costco without the acoustic tech. It would be lighter so you will get slightly better range or Wh/mile. "

I doubt that the slightly reduced weight would make any significant difference in efficiency (range or Wh/mile). It would be the difference between driving before and after a Thanksgiving dinner; a few extra pounds don't matter much.

I was at Costco to order the Michelin primacy MXM4 run flat tires for my BMW. The run flat tires cannot be ordered from Costco sites. But the Costco staff called Michelin to order the tires for me. I got the Costco discount.

dmastro | September 10, 2018

I think the lead has been buried... the tires lasted less than 18K miles? That seems like an exceedingly short wear period.

I've had summer rubber on a directional, staggered setup that can't be rotated that lasted twice that long.

Is this typical of these tires?

Good info on the Costco tires btw.

efuseakay | September 10, 2018

Don’t any of you use your radios? :)

When my P+ tires go, I’m not going to worry about acoustic tech, or necessarily even replacing those expensive tires with the same model. There are other decent and less pricey tires out there.

djharrington | September 10, 2018

@dmastro: the ones on my S are about 60-70% towards replacement at 35k miles

dmastro | September 10, 2018

djharrington: That sounds much more reasonable. I hope your experience is more the norm.

vmulla | September 10, 2018

Info about my tire wear:

My tires are stock 18" Michelin Primacy MXM4s.

5/32 Front and 7/32 Rear at 11K miles (after first tire rotation)

When I noticed my tires were wearing out quickly I switched to chill mode

3/32 Front and 5/32 Rear at 16K miles (after second tire rotation)

Chill mode helps tires last 33% more for me, that's quite a bit.

Coastal Cruiser. | September 10, 2018

vmulla has been "driving" his car. Ha ha.

Nice reporting on those tricky tire part numbers detective vmulla.

Iwantmy3 | September 10, 2018

So do we have any idea if the difference is at all significant? I don't want to get sucked into a more expensive version of the same tires over a gimmick.

Also, is this acoustic tech the reason that has been given to people in these threads as to why the tires can't be plugged?

TexasBob | September 10, 2018

Are you going to put in a warranty claim with Michelin on this? The tires are warranted for 55k or 6 years on pro-rata basis. Would like to know if they give you credit for early wear.

sgnatiuk | September 10, 2018

Shit my sticky summer tires on my WRX last about 35k miles per set, and I am a very spirited driver. Less than 20k is absurd!

ST70 | September 10, 2018

@vmulla- Did you call Michelin about the warranty? I had to go through Sears to get the warranty credit....I'm about to do that again soon.

lbowroom | September 10, 2018

Usually tire manufacturers do not cover OE versions of tire for premature wear, only the retail version. It's in the fine print somewhere. They refer you to the auto manufacturer for OE claims

js1000 | September 10, 2018

If you don't care about road noise then you might want to look at Continental ExtremeContact DWS06. Less costly, longer lasting, and a better tire.

dmastro | September 10, 2018

I've used Conti DW's before (can't recall the specific style) and liked the tire a lot. I replaced the trash Bridgestone run-flats on my BMW 3 and loved them.

vmulla | September 10, 2018

I'll look into the warranty aspect and report back here.

burdogg | September 10, 2018

Um - actually Michellin does cover OE versions - I just had to replace my S tires - same tire as the 3 - and it was at 30,000 miles - supposed to be 45,000. I had to jump through some hoops, but all that was needed was a tire inspection - I first went through Michellin, opened up a claim, went to Discount tire, but since they don't do it - Discount Tire did the tire inspection - talked to the guy on the phone (I had to call from Discount and do it there, got him to talk to the discount tire rep after tire inspection was done) and about a week later, Michellin called me saying I would be receiving a check for $240 and just confirming my address. It took maybe 1-2 months from then to get the check, but it did show up.

Michellin was great about it and the first time I had ever tried doing a warranty on tires. So yes, at least Michellin covers the tires.

burdogg | September 10, 2018

Normally the way it works is the place you got new tires at would just discount the amount Michellin was warranting and Michellin would then work with the tire place - but Discount was not one they work with, so that is some of the hoops I had to jump through - but was really easy actually and was super glad when I received the $240 check that I spent the couple minutes on the phone at Discount with the Michellin Warranty person.

jamespompi | September 10, 2018

Do you have to have logged rotations from a shop to not void the tire warranty? I was just going to swap them myself..

slingshot18 | September 10, 2018

Michelin Pilot Sports on my S3 last 12k, so 18k is great! lol

slingshot18 | September 10, 2018

Typo. Audi S4.

burdogg | September 10, 2018

In my case - My S is a D so I never rotated the tires - the wear was even. So that is what the tire inspection was - to make sure the wear was even, that there was nothing abnormal that caused the excessive wear. There was no asking me if I ever rotated them or any other questions to me. It simply was a tire inspection and after they did that, they talked to the Michellin rep and all was good from there. I would assume if say, the backs were completely worn, and the front weren't at all, then the warranty wouldn't kick in :)

jamespompi | September 10, 2018

burdogg, thanks

burdogg | September 10, 2018

No problem - the only way I even knew about tire warranty from manufacturer was from these forums so happy to pass on what I have learned as well :)

TexasBob | September 10, 2018

Just to confirm fro the Michelin warranty website: "All MICHELIN® tires (both Replacement & Original Equipment) come with a limited warranty for treadwear, as well as a limited warranty which covers defects in workmanship and materials for the life of the original usable tread, or for 6 years from date of purchase, whichever occurs first. Mileage treadwear warranties vary by tire line. For the specific mileage treadwear warranty for your MICHELIN® tire, see Michelin Brand Mileage Treadwear Warranties."

The Primacy MXM4 (18's with the W rating) have a 45,000 tread-wear warranty.

Michelin's customer service from the warranty document is: 1-800-847-3435

Tesla warranty also says Tires covered by manufacturers warranty.

Coastal Cruiser. | September 10, 2018

burdogg making an evermore rare post? And multiples at that.

All his Tesla's must be on the charger.

lbowroom | September 10, 2018

Wow, that's surprising! Seeing as how I'm getting a Performance with 18s, I think Michelin is going to be cutting me some checks in the near future.

hokiegir1 | September 11, 2018

UGGGHHH. Had a post typed up, and then when I hit "save", I got logged out and lost it. Hopefully, I catch everything I intended.

@vmulla -- Hubby pointed out to me that the measurements you are reporting sound like they are being measured from the wear bar (which is at 5/32) rather than from full tread depth -- which would mean that the 3/32 you have would actually be 8/32, and that's more or less in line with 17.5k miles, so I just wanted to make sure that you double checked whoever was measuring was doing it from the right place.

We just got our 2nd rotation at just under 12.5k miles and have not noted any unusual/excessive wear -- and we don't use "chill" at all. ;)

vmulla | September 11, 2018

@hokiegir1,
Thanks for the input. If what you and your husband are pointing out is true, this tire wear issue was much about nothing.
However, I measurements were taken and tires were rotated at Tesla Service Center. Additionally, the tech mentioned that I'm coming up towards the end of tire wear. 2/32 is the legal limit for tire wear, and my front tires are now at 3/32 is what he mentioned.
Just to be sure, I'll get a second opinion from Costco - they typically do small things like this without a fuss.

vmulla | September 21, 2018

Ok. Time to wake this thread up again.

I confirmed that the tires are truly at 3/32 (Front) and 5/32 (Rear). They are not measurements from the wear bar as @hokiegir1 (and husband) have suggested.

This is good info since I now know I have to replace tires before Jan 2019 to pass inspection (min tread is 2/32 to pass inspection) my car will not make it. Anyhow, I want a safe car for the coming winter and plan to replace the tires ASAP.

That brings us to the next step of getting replacement tires - Warranty.

Here's the chat conversation with a Michelin representative about claiming warranty (Copy Paste Follows):

You :
Hello my tires are wearing out much earlier than the rated mileage. I would like to claim warranty. Can you please help me do that?

12:19
Amanda :
Hello, I will be happy to assist.
12:20
Sorry to hear you are having that wear issue. May I ask when you purchased the tires and from what tire dealer?
12:21
You :
Hello Amanda. I got the tires with my new car. The dealership is Tesla at Tyson Corner VA

12:21
Amanda :
When did you purchase the tires please?
12:21
You :
I got them new in January 2018

12:21
Amanda :
Thank you. May I have your name, email and phone number to start up your claim? I can then explain how our process works.
12:22
You :
My name is ######

12:22
Amanda :
Thank you, ###. What we would need now is a tire inspection to be done by one of our dealers. Would you like to return to the selling retailer, or would you like some options of dealers in your area? Please keep in mind, wherever the inspection is done, is where the credit (if offered) will remain.
12:23
You :
Yes I'd like to return to my original dealer. That's actually the Tesla Service Center - I'm not sure if they're considered a tire retailer.

12:23
Amanda :
Okay great. Once you are able to stop by for that inspection, you may let them know you need a tire inspection for a warranty claim. Then simply have the dealer call us at 866-866-6605 with the results so we may determine warranty credit. The claim is saved under your phone number, so that is your claim/reference number. If a credit is offered, it should be applied at the register and will be valid for any Michelin, BFGoodrich or Uniroyal tire for 14 days.
12:24
You :
Oh Ok.

12:24
Amanda :
Is there anything else I can help you with today?
12:24
You :
Yes, I would like to know how the credit is calculated. And when will I know if I am getting a credit?

12:25
Amanda :
Since we do not have inspection results, i cannot advise how our credit was calculated. As soon as we speak with the inspecting tire dealer, we may provide an offer right then and there.
12:25
You :
Oh thats good. But can you confirm if my vehicle dealership is an authorized Michelin Dealer?

12:26
Amanda :
Yes.
12:26
You :
Ok. Thank you very much for the info.

12:26
Amanda :
You are welcome. Is there anything else I can assist you with today?
12:26
You :
Nope. Thank you for everything

12:26
Amanda :
Thank you for contacting Michelin Consumer Care. Have a great day!

The_Flash | September 21, 2018

thanks vmulla. this is very helpful. :)

ST70 | September 22, 2018

@vmulla- Nice!.....and??? Did you contact Tesla? What's the next steps? If you rotate you should be good for another 3-5K miles

ebmcs03 | September 22, 2018

Wow. That’s good of Michelin. Makes me more confident in buying them again in the future.

lbowroom | September 22, 2018

I wonder what Michelin will do if they start receiving thousands of mileage warranty claims.

burdogg | September 22, 2018

vmulla - that is my same experience with online chat - except I had already bought my tires from Discount Tires and had an appointment. So I told them that and they were fine with that - I just had to get Discount to do a tire inspection (they are not on the list) and call that number with my claim.

The hoops I had to jump through...Discount tire did the tire inspection - but after going to the manager etc...they had no way to take care of the warranty for me (I called BS but fine). So, as I waited, I called into the warranty number that THEY should have called.

Now the hoop - They had no claim number for me, even though I did exactly what vmulla had done :) So, the guy was very helpful and we started the process right there. Then I was able to just had my phone to the person who did the tire inspection to tell the Michellin agent the results. After which, I talked to the guy again and he said I should be receiving a check from Michellin in the mail (as noted in vmulla's chat, it usually is done by giving you credit off your tire purchase right there, but instead in my case, a check was to be mailed.)

So, a couple days later, I got a call from Michellin. They said my check was ready and they wanted to confirm the address before it got sent out. We confirmed the address. It took about 4-6 weeks from then to get my check.

All in all - I was very impressed with Michellin in this regards. There was really no hassle with them...just Discount Tire. Definitely love Michellin not making a hassle to claim the warranty.

vmulla | November 16, 2018

Update - Costco now has the Primacy MXM4 acoustic tires. Part #16144.

Yay!!

Also, Michelin gave me a 35% off the new tire invoice.

Getting tires from Costco is now a no brainier.

CharleyBC | August 22, 2019

Confirmed at Costco in Sac today. With acoustic tech: $269 for the 18s. He said also available in 19.

jebinc | August 22, 2019

Good news!
