285's or 295's for MYP at front and back/square set up

[Flyby]

Fronts are bit more delicate since you don’t want any rubbing when the wheel is turned. I have a friend with a MYP who has 275/35/21 in the front and it rubs when making parking lot maneuvers, nothing major tho.

For my MYP, I will be doing 265/40/21 and 285/40/21. I want a bit more sidewall to fill in the wheel gap, increase comfort and hopefully increase durability against potholes.

I thought i posted earlier in response to this but can't find the post . reposting here.

How did the 265/40/21 and 285/40/21 setup turn out. Any issues in ride quality or rubbing anywhere at turns. I am thinking of doing the same or possibly a square setup for my winters with 265/40/21's on OEM wheels for MYP. Does anyone have any pro's con's ?

Curious if you did get the 265/40/21 and 285/40/21 setup for MYP. How is the ride quality and any rubbing on turns ? I was considering doing the same or potentially even a square setup with 265/40/21 on stock OEM wheels for MYP. Any Pro's or con's from anyone on these setups..

Re: 265/40/21 F and 285/40/21 R
Is that what you went with? Does it work OK?
I know it could pose a problem in some (maybe most) traditional AWD systems to have almost a .75" tire height difference front to rear. I guess it's ok in EV's?

on the stock 21" uberturbine?

Also.... with all these tires going up and down in size, how would someone go about correcting the speedometer/odometer discrepancy?

 

[akballow]

275/40r21 is the max the fronts will fit. I have 265/40r21 that fit no problem. 295/40r21 in the back made my camber slightly more negative.

Where do people find shops that carry 265/35/21 (or 265/40/21) and 285/35/21 and AS tires too? It’s so rare to find one.

I just put on 285/35R20 in a square set up. Wheels are 20x10 with +40 offset. On a stock 2021 Model Y. No rubbing. Hadn't seen anyone confirm it fitting on a stock set up.

Looks good! I just put 255/40/20 275/40/20, definitely might go with 275 or 285 square the next time around.

I just ordered 295/35/21 for my rears and will swap the 275’s to the front wheels.

Anyone done this with the Michelin AS4’s?

Will my 295 rears be too tall? .5” I think

here is the clearance with a 285/35/20 on a 10.5x20 wheel. If it helps you.

Thx. So the 295/35/21 should fit just fine on the oem 21 Uber 10.5 rim. Clearance will make it.

Front 275/35/21 will fit as well.

Diff will be .5” between front and rear in total diameter. But stock oem 255/35 and 275/35 is already .5” there anyway so visually won’t make much diff there.

People have definitely reported doing just that without any problems.

What lan

What’s interesting is the .5” variance between front and rear diameter. But on oem 255/275 it’s the same .5” variance.

One thing to keep in mind is that tire tread profile. I went with Nokian R3 on the stock Uberturbines at 265/40/21 and 285/40/21 and the fronts barely cleared the upper knuckle - maybe a 1mm before touching. Michelin and Contis fit without issues.

Summer setup at 265/35/22 and 285/35/22 with flush offset and lowered 1.5” - no issues.

Here’s a pic of 265/40/21 Nokians - very tight but no rubbing.

Been looking for someone who’s done this! Curious after a few months any regrets?

How big was the efficiency hit?

Any issues with more debris hitting the paint?

No running issues since?

Thx!

Was planning on Fast 20" FC04 wheels, which only come in 9.5" width (well, and 8.5").

Any issues with more rocks/debris hitting the paint? Wheel looks like it is sticking out quite a bit,did you add spacers or is that just a factor of the 285 width? What offset on the wheel?

 

[Mattemsmy]

my model y is fully covered with ppf film. They do stick out and I do not have any rock or mud flaps on my car yet. I do not see any damage yet but I only have about 1k miles on the new set up. The wheels were 38 or 35 offset I believe. It has a little poke but I’ve seen worse. Also I was told that I would not need rear camber/caster bars for alignment. Well I can say that I do need them as they cannot align the rear of my car To spec.

What do you mean you can't align the rear to spec? Going with 285's on a 10" wheel, 45 offset, which would stick out substantially less if you did get a 35 or 38 offset + 10.5.

When you say "they can't align to spec", do you mean your tire shop or Tesla?
