TESLA Model 3 long range rear tires replacement

[vzaitsev]

HI everyone,

I need to replace rear tires for Model 3. Odometer number is at 18K. Discount tire suggested replacing with MCH PRIMACY MX4 . I need some inputs in deciding between Primacy MX4 and PILOT 4S and PILOT 4.

I am inclined to get one with better insulation of road noise, quieter & better mileage.
Would using PILOT 4S or PILOT4 decrease battery performance ?
Is PRIMACY MX4 has better handling and traction?

Completely different tires. Pilot are sportier and such have stickier rubber and will lead to a small decrease in efficiency. If your main goal is quiet and efficiency, stick with the primacy. in either case, for quiet operation, make sure you get the version with the foam.

Conti makes some good tires as well. with only getting 18k on the OEM Michelins... i dont think the Pilot Michelins will last much longer. lots of fast 0 to speed limit at traffic lights?

the 4S has much better handling, traction, and much shorter braking distance

All of which is due to being a stickier tire- which means worse mileage

The MXM4 stockers are pretty mediocre at just about everything.

yes. My preference is quiet operation and i am ok with losing some efficiency over better handling and traction.

How much of decrease in battery performance can we expecte between PRIMACY and 4S ? is it around ~2-3 % ?

thanks for reply. Do we expect a huge difference in mileage between PRIMACY and 4S ?

More like 10% from my reading.

Though in exchange you get about a 20% reduction in stopping distance (on top of better handling)

Discount tire said only MIchelin Primacy MX4 has foam in it and PILOT 4S doesn't have any kind of foam that suits tesla Model 3 18.
so I have ordered PRIMACY MX4.
I read some posts regarding having 4S some acuoustic foam. Not sure if they are available for 18" wheel.

I would think this is correct. Tesla only offers the Pilot Sport in 20” so they don’t have a custom “TO” model for the 18. Sounds like you made the right choice.

FWIW the acoustic foam makes a very tiny difference in sound.... but MXM4 vs PS4s is a very large difference in performance and stopping distance.

Michelin does homologate for Tesla a Pilot Sport 4 in 18" with the acoustic foam.

It's a slightly different than Pilot Sport 4S, but very similar in performance

would it make a difference if i have front tires from MXM4 and rear from PILOT 4S ?

It is never advisable to mix tires if you can help it. You will affect the handling of the car (understeer/oversteer, wet weather traction differences front/rear, etc).

Yeah, that'd be worse in every way I can think of

Ok. I didnt know it. So i would just stick to PRIMACY for rear tires replacement.

Thanks everyone for your replies. Appreciate your responses

This is the Pilot Sport 4 with foam (TO Tesla, Acoustic Tech). I'm also hoping to find out the efficiency difference compared with MXM4 though.

Please please go to school on my recent experience. Primacy OEM are junk with inner foam. Mine lasted 12,000 miles. You want to install Cross Climate which are #1 rated on tire rack. They are no joke legit in dry and rain and light snow. There is no downside unless you plan to track your car.
