Does stud thread pitch matter?

[Ernie2d4]

New owner of a ‘20 Model 3 Performance looking to get spacers.

I see that there are a few Tesla model specific options available but like most of us I’m always trying to save money.

I know I need a 64.1mm bore spacer with the 5x114 pattern, and I want to go with 25mm rear and 15mm front.

The only thing I’m unsure about is the thread pitch. I know the stock studs are 14x1.5. I found a really nice looking set of Acura/ Honda spacers for wayyyy cheaper than what the Tesla specific spacer company’s are asking. They match everything I need EXCEPT the studs are 12x1.5.

Will this matter? And even if the threading is different could I just get new lugs to match that pattern?

Thank you in advance for any help!!!

12x1.5 won't let you safely use required lug nut torque spec. Are you going to loose a wheel? You certainly increase a chance of that.

Yes this matters a lot. I'm an ME and I deal with fasteners and thread pitch all the time. DO NOT try and get creative. Is it really a savings if your wheels decides to leave the car while you are driving.

14mm vs 12mm shouldn't be thought of as thread pitch, but stud thickness.

Going to thinner wheel studs than stock is a bad idea. Especially on a heavy car like a Model 3.

More than that, they just won't fit. The holes in the spacer will be 12mm. But your studs will be 14mm. It won't on the car.

That said, you can get 15mm spacers for about $32 and 25 for $36:

We share a fitment with Mustangs....

You would need longer hub studs with spacers.

You would need longer hub studs with spacers.

Look at the link above. The wide spacers he is considering bolt to the car and then have their own studs.

11.7 vs 13.7 mm minor diameter of the stud.

107.5 vs 147.4 sq mm of solid steel, so the 12mm studs will have around 73% of the strength of the 14mm studs. Don't even consider it.

So you spent $40k+ to buy a car, but can’t get proper spacers? Like someone said Mustang spacers will work and are cheaper? than Blox that are advertised for Tesla.

Blox spacers are marketing. There is nothing special about Tesla wheels or hubs. The Model 3 fitment is identical to modern Mustangs. This is a good thing.

If you really care about "the correct thing" - it isn't spacers, it's buying wheels with the correct offset. But of course, the stock wheels are the correct offset, so this is about looks anyway.

Re-read my post lol. You just made an essay about what I said in a sentence.
