20x8.5 Wheel Owners: how do 255 tires look?

[BodegaBay]

MYP owner here and looking to downsize from 21" to 20" for a square setup. I'd like to stick with 255 stock width. A square shouldered look is preferable; not interested in ANY stretch.

A 10" width wheel is too wide for what I'm looking for and I don't see any 9" wheels. I guess my option is 20x8.5. How do 255 tires look on a 8.5? Is it just right or meaty?

There are some dedicated threads here so you should try a search. ;-) I think 245's would be the max on an 8.5 if I'm not mistaken.

Just to make sure I understand the question—you are not selecting tires by their rolling resistance, their sound level, or their aerodynamic qualities, but by their looks? You have an aesthetic preference for certain tire shapes?

No no. I'm not discounting the ratings, specs, or type of tires. I'm simply asking how a stock sized 255/40 tire would look on a 20x8.5 wheel. Stock 20x9.5 wide and will accommodate 255 fine. The problem with aftermarket is they are mostly in 20x8.5 or 20x10.

This is a Model Y forum section. You're asking me to look at a Model 3 thread which would not do me any good.

I can tell you right now that your choice is not a wise one. You'll be off by negative 42 revs/mile.

That said, I am running 245*35*20 front and 275*30*20 rear. But obviously on non-stock wheels.

Mmmmm this is the Model Y forum section, no? Tire 1 is a Model 3 Performance tire.

Ahh, fair enough. My bad!

This is a 255 on a 20x9, +34 offset. You should be fine with 8.5 and 255.

Thanks PT. I saw your pics on FB previously and was going to ask you about those CF10s since they are one of the few that offers 9.0in width. I've read that the Forgestars only carry a load rating of 1600lbs; any concerns there since I think stock min is ~1900lbs? Also is that pic after the MP coils were installed?

Since I'm not towing and I won't be doing any drives with 5 people in the car with 200-300+ lbs of luggage, the 730 kg load rating won't be a problem for me.

Yep, the image is with the MPP coilovers. Roughly 1.75" drop. I'm going to most likely lower it another 1/2" in the future. I just want to drive it for a bit to see how things are at this ride height and speed bumps, drive ways, etc.

pt19713, you nailed the look. Could you be post the specifics on the tire/wheel combo along with the suspension/alignment details? I am a newbie to Tesla, so, the more details the better. I've been hot rodding cars my entire life, but, I'm new to Tesla speak.

What are your front and rear toe numbers?

 

[pt19713]

What are your front and rear toe numbers?

LF -0.04, RF -0.05
LR 0.17, RR 0.28

LF -0.04, RF -0.05
LR 0.17, RR 0.28

Why such high RR toe? Did you max out adjustment?

 

[pt19713]

Why such high RR toe? Did you max out adjustment?

It's within spec. Rear toe spec range is 0.05-0.35. I'm fine with more toe out since it increases the rear oversteer, fixing a lot of the inherent stock understeer. The rear end rotates a little quicker and feels snappier.
