The quest for wider wheels and tires, 295, 305 and beyond...

Getting a little worried about the traction control freaking out from tire diameter. It seems tesla only lets you set wheel size from a list of stock sizes? My wheel/tires are currently 28.7" which is like 2" over the stock 20's. Assuming you can't change it accurately and they fit ok, I guess we'll see how the computer likes it.
 
Welp, front won't even kind of fit. Tire too tall to clear the control arm. Guess it's time to figure out what tire size to redo these with.

I'll give you A+ for trying haha but I knew there was no way that would fit.

What's your offset? That should help determine what size tires you need. We are quite familiar with the 20x9 / 20x10.5 sizing.

Ok, so just ordered some DWS06 Plus' in 295/30r20 and 255/35r20. I think we're gonna be good now when they come in next week. The front still has me nervous but I'm crossing my fingers. The rear will be good. In case anyone was wondering, here's what 315's look like on the back with that 20 offset hah. I think you could make it work with some fender flares.

A few people here have been discussing the possibilities of getting wider wheels and tires under the Model 3 for track/autox use. So it is about time to start a public thread to see if the community has any good input.

What we know fits:
18x9.5+35 with 275/40-18
19x10+30 with 275/35-19

The next step to test:
18x10.5+25 with 285/30-18 then if that fits try a 295

Here are a few pics I took with at full compression. This was on the 18x9.5/275 setup with no spring and the car on the bumpstop:

A few things to note:
a. Looks like 1/2 inch of clearance to the inner lip and 1 inch to the outside.
b. The car at full bump is LOW.
c. This was with stock camber. So adding some more up front will make a lot more tire room.
d. There is a bit of a lip on the inner fender that could be cutoff. I think these are plastic fenders? So we can't roll them.

Next questions:

1. There is way more room in the rear. Has anyone tried a staggered setup on an AWD car? What about different diameters? Fitting a 305, 315 or even 335 in the rear seems like it would be possible.
2. What about the gearing? Going to these shorter 18" wheels we are hurting the gearing. Has anyone tried comparing the acceleration at high speeds with short 18s vs tall 20s?
hi i just put some 19x9.5+30 wheels on my P3D with 275/35/19 DWS 06+'s. when you say we know 19x10+30's fit, does that include the P3D? i just found out i can't adjust camber on the front end, so i'm hoping "fits" means with stock suspension and stock alignment settings? thx.
