Looks awesome! I get asked at superchargers all the time about them.View attachment 977380View attachment 977381
Went ahead with the 40s yesterday and have to say that visually they are incredible. I was a little worried that being an older driver, I wouldn't like the look of them but honestly pics do not do it justice. Haven't driven them enough to comment on ride quality or battery usage yet, but so far I'm really pleased with them.
It’s not about larger or smaller tires, it’s about the delta between front and rear, or left to right for that matter. I’m curious if there is a potential binding issue or does the computer manage the delta for you?There is no ideal combo. but the difference has had zero downside for me. im on my second set of the larger tires.
You're overthinking it. the difference isnt big enough to have a noticable impact. get an alignment and there is no problem. I drive like a madman on windy mountain roads and highways as well as snow/rain/mud traction control is perfect, suspension is perfect. everything is in good shape with my car after running through a full set of these in 37k miles. wear was even too.It’s not about larger or smaller tires, it’s about the delta between front and rear, or left to right for that matter.

Alignment has nothing to do with it. It’s about how the car functions to keep the wheels spinning at the correct rate. What you’re suggesting would prove detrimental on many vehicles with traditional transfer cases.You're overthinking it. the difference isnt big enough to have a noticable impact. get an alignment and there is no problem.

Weird hill you are fighting on.. To be strictly speaking, as long as each drive unit has similarly sized wheels it will be fine.Alignment has nothing to do with it.

And the impact wouldn’t be noticeable, but it could prove to have a negative effect.
If you go in for warranty work for your drive unit(s) at some point and they realize that your motors had to spin at a different ratio front to rear, than what is programmed/expected, you might not be able to defend your claim.
nope. people have been putting larger tires on cars forever. these are only slightly larger. handles like a dream, and had things checked out about a month ago. everything's perfect.OP, have you thought about premature wear on your front steering assembly having bigger thus heavier set of tires?
I wouldn't. Pirellis will give you half the milage. they are not great tires unless youre on perfect freeways 100% of the time, or using them for track.If I were to go for Pirelli P zero 295 35 21 whice would you choose? Looking on tirerack all of these are made specifically for other branded cars. Eg. Porsche, BMW, Maserati etc.
Thanks
@Raurele , you still noticing the above or was the issue more related to FSD Beta version and the issue went away after some updates?I dont know if it's the new beta version, or that the car thinks its going slower than it is, but ive noticed that on AP/FSDbeta, it is taking turns a little wider and sometimes touches the lines on the outer edge of the turn if im going above 50mph. I'm pretty sure it's the speed issue.
How can you assure that? I know a lot of folks are running non factory staggered sizes, but I haven’t seen evidence that’s it’s, in Tesla terms, within spec.Weird hill you are fighting on.. To be strictly speaking, as long as each drive unit has similarly sized wheels it will be fine.
Ergo, as long as your left and right is same model size, you'll be alright. Model y doesn't have mechanical linkage in middle connecting front axle to rear.
To reiterate, Model Y is fine if front and rear tire sizes are little different. If you swap out tires, just reset learned tire setting and have fun driving. Small differences are within design boundary condition.
So you are right about worrying about 'what is programmed/expected' and let me assure you, that the margin is fairly wide.
It’s not really something I notice anymore.@Raurele , you still noticing the above or was the issue more related to FSD Beta version and the issue went away after some updates?
Have you ran the 40s on both sets? Trying to find someone who has ran 275/35/21 295/35/21 and 265/40/21 295/40/21 to see which they liked better. I’m personally leaning towards the 40s.There is no ideal combo. but the difference has had zero downside for me. im on my second set of the larger tires.
No idea honestly... I went wider because the rims looked silly being out farther than the tire. if youre just looking for a wider looking stance, get some spacers.What about 315 and 275? Impossible?
So what OE brand did they put on your car? R01, N0, N1, M0, MGT?But if it's requiring you to put in a car that has that size OEM, I had to select "2021 JAGUAR F-PACE SVR" for the 295s. when I showed up with my Tesla they dint have a problem with it. just made me sign a thing saying im aware that the 295 isnt the OEM fit for my vehicle.
Is this the current consensus?So I've been trying to keep up with this thread and I see two primary variations in upsizing that people are doing. Trying to summarize:
Stock Option A ("Upsize") Option B ("Supersize") Front 255/35/21 275/35/21 (moved from OEM rear) 265/40/21 Rear 275/35/21 295/35/21 295/40/21 Notes Increases sidewall height 0.27" and width 0.78" (rears) Increases sidewall height 0.86" and width 0.78" (rears) Pros 1. Better ride?
2. More "full"/square look on rims (less rubber band look)
3. Minimal (<1%) impact to speedo measurement1. Great ride?
2. Visual heft/fills out wheel wellsCons 1. Ride isn't great
2. Tires look like rubber bands stretched over the rims1. $$ 1. Significant (6%) speedo inaccuracy (reading 70 = 74.2)
2. $$$$
Does that about sum it up?
I actually am not sure I've seen direct comments on ride quality from people who have done Option A (Upsize), but maybe I just missed it because sometimes I'm trying to piece together comments across multiple posts to figure out who did what. The Supersize folks have definitely made it clear it improved ride quality significantly.
Magbak Rimcases plus a set of spares and a Sharpie Pro for when something goes wrongIs this the current consensus?
I just picked up a 23 MYP and I’m concerned about getting my rims getting curbed in NYC. I was thinking of something thicker to protect them…what’s the best move?
