255/45R20 Tires on the 20" Inductions?

Quick Photo

Looks more like a real SUV.. and less like a hatchback Model 3. Great job!

Has anybody installed the Michelin Pilot AS4's in size 255/45 on the factory 20" Induction?

Trying to do comparison pictures of the 255/40 (OEM size) vs 255/45 (taller & cheaper) vs 275/40 (wider, taller, most expensive.. but also most wheel protection and best looks)

What PSI do you all run the Vredestein quatrac pro’s at? On 255/45R20

I just set mine to 42 psi. But I never really thought about it. Curious to see what others are doing.

I asked because as I was googling around, I was reading how there are actually 2 tire PSIs:
1) Vehicle Manufacturer recommended - typically aligned to getting the best EPA mileage out of the car
2) Tire Manufacturer recommended - more treadwear life oriented. I couldn't find the Vredestein Quatrac Pro's recommended PSI -- only found the MAX of 51.

So curious if you all have experience with how treadwear happens over other PSIs aside from 42... 45...

I just installed 245/45/20s on my car. Firestone firehawks. The drive home was quiet and smooth. Over the 37k miles I have had my standard range Y I averaged a very consistent 254 wh/m Lets see what these different size tires do. I realize the car will be going faster than the speedometer. I am not sure if the wh is determined by odometer miles / energy used ? if that is the case, it will think the car is less efficient. In reality, you are going about 2.4% more.

Extremely interested in your results. As I have the exact same vehicle, have driven 35K miles on the OEM Goodyear F1 + 20" Inductions and my life time wh/mi is 257. Good chance I'm going with the 275/40R20's.. as the only tire I want to purchase is the Michelin Pilot Sport AS4. And from all reports.. the 255 on the factory wheels seems undersized and extremely stretched. Someone just posted these pictures on facebook:

Meanwhile someone on this forum posted a picture of how the same tire in the wider 265/40 looks on the 20” OEM wheel:

after about 300 miles, I am about the same efficiency. Ill keep you updated. The tire looks too narrow on the induction rim. Honestly the rim should be half inch narrower for the stock size tire

After reading all of these posts, what's the consensus on improving the ride for the 20" inductions? 265/40 or 255/45?

Both appear to have a bigger side wall. Maybe the 265 helps with curbs as well? TIA

Does anyone have an update on using 255-45-20 tires on model y long range with induction wheels?

Yes they work great.

Yes they work great.

How many miles do you have on tires and thanks for quick reply.

I love my 255/45/20 AS4's. On MPP Coilovers, dropped 0.5" and some sound deadening. Once I got the new tires (which were like $70/tire cheaper than 255/40/20's), they instantly felt more cushiony. I just feel like that made a huge difference, anyone else agree?

Do your tires look undersized just as the previous pics of the 19 inch wheels with 255-45-19?

12k miles on my cross climate 2’s. No complaints whatsoever.

Some fresh rubber installed 255/45/20 ran this size on my winters and like the look and feel better than stock might go up to 265 next time we’ll see

 

[JonB65]

About 2k miles on my Quattrac Pros. Really like the slightly more cushioned feel. Speed is 1 mph over what is displayed. Not an issue. Glad I did this!

I’m at over 20k miles and no complaints. 255-45-20 Crossclimate 2 on stock Model Y induction wheels.
