Maximum Tires Size Model Y Performance?

[FlyGuyM0delY]

I am trying to determine what the maximum tires size anyone can confirm so far on the MYP. I just swapped over to my winter setup, but will to replace the Pirelli’s come next spring. I am running 20mm spacer in the front and 25mm spacers in the rear.

I would like to run Vredestein Quatrac Pro’s.
Front:
275/40R21
Rear:
285/40R21

I believe I have seen some members post the rear size being okay, but I believe the front might be a little ambitious?

Any input would be greatly appreciated!

I just had MICHELIN PS AS4 265/40R21 fronts and 295/40R21 rears installed. So far so good, but those rear tires are huge with over 4 1/2" of sidewall.

Nice! Got any pics? Notice any difference in how it rides/feels/sounds?

Pics? Especially interested in the rears….thanks in advance!!

Please post pics from the rear showing the stance and tire width.

Can you post some photos of your car so I can see what those 295/40ZR21's look like?

Here are some photos of the MICHELIN PS AS4 295/40R21 rears. The handling, ride and sound are all noticeably different with the 265/295 setup compared to the OEM Pirellis. The MYP is still is very confident in sharp curves, both my wife and I felt the ride is improved and although the sound is different on each road surface, cannot say it is any louder. Did the speed sharp turn/speed bump test and did not hear any rubbing.

Nice, looks like it fits just fine! And there definitely appears to be a bit more protection for the wheels. Stoked to mount these next week.

In case you are interested, the stock Pirelli 255/275 tires are in the top photo, and the Michelin all season 275/295 tires are in the bottom photo.

So are we looking at 275/40R21 (29.7" Diameter ) front tires and 295/40R21 (30.3" Diameter) in the rear? If it is and it works with zero rubbing I am sold! It looks so perfect. I was thinking it was have a crazy tall side wall but it still looks factory.

I was considering installing Front: 265/40ZR21 (29.3") and 295/35ZR21 (29.1") to stay closer to a "safer" 29.0" total matching diameter. I am trying to avoid having to get a separate designated winter set of wheels. If we can get away with 21's all year long by using a 40 side profile that would be best case scenario.

Even thought my 265/40R21 (29.3”) fronts and 295/40R21 (30.3”) rears are one 1" difference in diameter, they handle as good as or better than the OEM Pirellis and give a lot more pothole/rim protection.

They also match the 20mm tread width delta front to rear of the stock sizes (255 and 275).

I hope you’re wrong because I’ve got a set of 295/40/21 that I’m hoping to have installed next week. Others have managed 285/40 and 295/35, it’s only very slightly taller and rough measurements seem to indicate they’ll fit. But I’ve considered ordering a backup pair of 295/35 just to be safe.

Hey, do you have any update on this setup?

Yeah…

Michelin Pilot Sport All Season 4 on Uberturbines- 265/35 & 275/35R21

And by the way, whenever I replaced my staggered tires, Discount Tire always let me replace all 4, and they prorated the front two, since the rears were done at 20k miles, and the fronts had about half left. The first time I told them I had issues with stability control only replacing the...

TL;DR I ended up with 295/35/21 in the rear, and I’m happy enough. Another guy in that thread did 40s and they seem to fit.

Just completed a trip SF-LV-OC-SF with the Michelin PS All Seasons 4 265/40R21 fronts and 295/40R21 rear.

Trip saw rain and some snow at higher elevations so glad I had All Seasons.

No rubbing front or back.

Need to watch speed as it is ~6% greater with the bigger rear tires. For example 75 on the display is really 80mph.

Road noise different than the OEM Pirelli P Zero summer tires, but no louder.

These Michelins are noticeably smoother riding than the OEM Pirelli P Zeros. Most likely due to larger sidewalls.

I was skeptical of All Season tires having always run summer performance, but so far so good.

From a width stand point, 275 is the widest I have seen on MYP front. Quite a few folks with 275 40 20, with 28.7" inch overall diameter

The irony is that 275 is the perfect size for the 9.5" width rim. It's crazy how stretched the stock tires are.

I wonder why Tesla went with such skinny tires stock? Is it for aerodynamics or just having less contact patch for mileage?

255 is a wide tire for an EV already. They should have gone with a narrower rim.

255 is wider for EV already ...as in from a range stand point? My assumption will be that most of the MYP owners should be willing to sacrifice some range for better handling, looks , etc. BTW don't know if the range loss is a real with wider wheels.

Reduce efficiency losses. If they had put the right size tire, in this case a 275 for 9.5" front rim and 295 or 305 for 10.5" rear rim, range would drop a lot. Instead they stretched the hell out of the tires.

While in theory this may be true, I have 265s on the front and 295s on the rear, have a negligible amount of efficiency loss and overall couldn’t be happier. YMMV
