Tesla 19” sport wheels on Model 3 Performance with PUP?

[MasterC17]

Considering newer M3Ps only have 20' uberturbines as default - would it help the range if someone were to install 18' wheels on this car? Realistic to expect LR AWD range then?

It's all about the tires - wheels make almost no difference. A sticky summer tire is always going to consume more energy than a low rolling resistance all season.

Hey, stumbled on your comment and had to ask -- I just got a 2021 M3P, I wanna swap out the 20" stock wheels for my 19" sport (Rohana RFX2) 19x8.5 +35 with 235/40/19. Do you know if these specs fit without issue?

I have 245/40r19 on my factory 19x8. you can put 250s on an 19x8.5

Yes, look at that outer cut ring.

I've got 19" sport wheels on my 2021 Performance right now.

I have a 2021 M3P and am looking to get 19" wheels with sport tires do you recommend a particular set? Spending $1500 a year on tires is getting a bit expensive

Plenty of options depending on your budget.

I was able to achieve the dual motor EPA rated efficiency with 18” wheels and PS4S “sticky summer tires” on my Model 3 Performance. With the 20” Uberturbines my efficiency was 10% worse with equivalent tires.

I actually don’t think the difference in rolling resistance is that great for cold and fully inflated tires. Hot and under inflated tires would be an entirely different story.

Which 18" wheels are you running? Thanks!

View attachment 473037 View attachment 473038 The 19inch oem wheel fit perfectly on a performance even with 380mm rotor and 6 piston Caliper!!

Aftermarket rotor nicely obviates the need however for the stepped lip that has to be machined into the wheel that allows clearance for the 'anomaly' on performance models with their ultrathin hat rotor.

TSportline TS5 18x8.5 wheels and 235/45/18 PS4S tires.

Did you leave the values the same for the wheel/tire settings in the vehicle? I see it is within 99% of the diameter and circumference, it may not need it. Just curious.

I have the Performance model so I had to switch the settings from the 20” UberHeavy wheels to the 18” non Aero wheels. Seems to work great after I switched that value.

Can anyone confirm if my aftermarket 19” Sport V2 replacement wheel will fit the M3P brakes? It’s a spare wheel for me.

It appears to have the step, although being aftermarket it's impossible to confirm without fitting it.

What is the “step”? I couldn’t figure it out from the prior photos lol. Thanks for the help

There's a shallow, secondary cut in the back of the center that is slightly wider in diameter. That's what we would refer to as the step.

And that helps it clear the larger brakes somehow? In my brain I’m thinking the outer lip would still be flush with the rotors

No, that allows it to bolt over your rotors. Otherwise, you would have a rather large gap there which would be quite bad.

The caliper clearance should easily clear assuming it's a near replica of the factory design. But, again, being aftermarket, there's no way to say with certainty until you try it.

Mounting flush to the hat is one thing. Calipers clearing the barrel is something else. As MasterC17 mentioned, it should but no guarantees.

Ahh ok thanks. I thought the issue the whole time was the smaller rims won’t clear the brake calipers on the P. Maybe that was just for the 18” stock Tesla wheels.

Ok simple misunderstanding on my part. I was thinking we were concerned with it sitting flush with the part of the rotor in green near the bolts, but it seems that the extra lip lets it sit flush over the part of the rotor in blue. Thanks for the help, makes perfect sense now.
