Wow, without lifting or spacers? 14.5% increase in width
In the USA we see people installing insanely wide rear tires on BMWs and the tire top tilt in and subsequent inside wear is very bad
Burning through $300+ tires

are you able to share your alignment results?

What alignment results… I said I haven’t gotten one lol

ah i thought you were getting one on this second set of tire change

 

[Raurele]

I haven’t…honestly I’m completely happy with my previous run on these tires mileage and performance wise. I drive 100-350 miles a day. An extra 2k Miles doesn’t mean much to me.

@Raurele wow you are a great tire test candidate
Remind me, what tires are you using now and have used in rhe past along with you positive or negative experience each

Thanks for posting this! Had no idea this was an option.

Don't mean to be forward, but would love to see some pics of the 40's from behind. Thanks!

Usually it takes at least a few dates before I can ask for pics from behind.

Also, is anyone running a different tire in these sizes, such as the Conti Extreme Contact DWS06+? Looking for something I can leave on year-round on my MYP, but still do well in snow.

Really a great review! I've read it like 7 times! LoL

Personally, I am not a big fan of Tesla's OEM 21" so I had my wheels produced (21' x F: 9.5/R: 10.5 x F: 40/R: 48) which I plan to wrap with Michelin All Season 4's F: 265 x 40 and R: 295 x 40. I would assume the set up will work for the Standard Model Y RWD as well?

Looks like the Costco $100 off 4 Michelin deal is back. But...am I correct in reading here that they won't install them since size isn't OEM?

I have 2004 wrangler and no one installs OEM. For Costco, my favorite, I order online which ships to the store and make my appointment. They just do the install. I’ve never been questioned as it’s not OEM.

315/R21's fit fine on the MYP though

Any pictures? What size on the front?

lol that was my question I asked, what size is on the front
think page 17 has pictures of a 315/35 R21 tires that fits fine, no rubbing

Thanks, I see it on page 16. But, it's a RWD Y (not MYP) and has a lift kit with spacers. Would love to see an MYP running them without a lift if it exists.

Yes, for about 20K miles I've run Conti DWS 06+ in 265 & 295/40-21 on stock uberturbines. These are A+ all-seasons with zero issues. The choice was based on 1) excellent experience with the same tires on a BMW X3 (sold) and 2) price -- several hundred less than the comparable Pilot AS4 (I think they're called).

Does this work? I want to stick with Costco for the larger tires. I asked in person and they said no. Im almost at 30k stock.

Awesome! Thanks for sharing. So tempted to do this right now before the snow falls, but not sure there's much market for used OEM tires. My MYP only has 7K miles on it, so trying to convince myself I might as well get as many miles as I can out of them before making the switch.

Regarding Costco, I get the impression that:
If you try to order these bigger tires for the MYP, they will say no.
If you order the tires themselves without specifying the vehicle, the order will go through and they will put it on.

Make sense?

That's what I plan to do when it's time for new tires on my MYP. At about 1k miles now so it'll be a while yet.
