True, but X has the special issue of not staying aligned at all suspension heights. Lowering links and aftermarket bushings can help reduce inner wear at Low suspension. Not driving in Low brings out the hard acceleration Shudder phenomenon over time.
I’m interested in doing what you did but I just want to confirm what you wrote. My understanding is that the slipstream wheels came in a 20x9.0" +35 for front and a 20x9.5" +35 width for rear. Tesla did have a short run of using a 20x10.0" +35 rear wheel but replaced it with the 20x9.5" +35 rear. Does that sound correct? So did you run non staggered on 20x9.0" +35?
The advantage might be the greater sidewall ratio. That will help with the pot holes as the freeze thaw cycle can create some quick road deterioration. I ended up doing a square winter setup using 265/45/20 all the way around on 20 x 9.0 rims. I had them test it prior to having the tires mounted to the wheels. I got them from discount tire. I would have gone with 19” rims but the selection was poor and there where more 20” choices.
I’m not sure I store them in my garage on a dolly which makes it easy to move around and out of the way.
@detdds do you happen to know if your 9.5" wheels on all 4 corners are with the 40mm offset or 35mm? I want to be able to go square with 275s and be able to move my rear 9.5" 40mm offset wheels to the front as needed without any fitment issues. I read one person say that my rear wheel will actually rub against the suspension but it sounds like yours don't, but maybe it depends on the offset. My wheels have the offset stamped on the inside of each wheel.
Rubbing I can handle b/c I know it's only when I turn it in each direction all the way. Sounds like you're confirming that the 40mm offset with the 9.5" wheels do in fact fit on the front of the MX. Sorry don't mean to be too AR but want to make 100% sure b/c I have to order the tires and will incur charges if the rear wheels will hit a suspension part if moved to the front. And what exactly is the rubber rubbing against? Hopefully an internal suspension and not the body panel/etc.
It's just the stock 20" rear wheels and 275 tires. When you put them on the front they rub, but only, as you note, when you're hard-over. But I don't know what they're rubbing on; I haven't investigated that thoroughly. I had the 275's on the front for most of one season, and it never felt unsafe and didn't cause any damage. But if I did it again, I'd probably go with 265's all around if on a square setup.
Volk TE37 - only the most JDM-sweet wheel ever made. I see no reason an 18" wheel wouldn't work on Model X, the front and rear brake package isn't that big, 355mm rotors with multipiston calipers fit under a LOT of sweet aftermarket wheels and the X uses a nice relatively low offset that helps with caliper clearance. My 355x35 4-pot Stoptechs on my M3 fit easily under an 18" wheel, and can even fit under certain 17's. Unless they have stuck some part of the suspension inside the wheel barrel that I haven't noticed. I'm sure somebody on here knows definitively, but I always have to prove these things to myself. If there's room for snow chains there has to be room for a 275 on a 9.5 with the right offset, I mean, look above, there's a guy running 10.5's all around with the 285/35-22 OEM rear tire size.
