20" Model X Slipstream Wheels on Model S

[SilverGS]

Great information on this thread. Currently I have 19 inch slipstreams on my MS, with 25mm spacers on rear and 15mm on front.

Question- is it worth updating to a 20” slipstream MX wheel? Not sure if it will be noticeable vs my 19 MS slipstreams.

**pictures before wheel spacers

It's all personal preference really. To me it's worth it, that's why I did that "upgrade".

Here's my car with the 20inch MX slipstreams (I had a tire blowout here, but the pics clearly show what the wheels looked Iike)

worth it is subjective on what you want to achieve. 19" probably is lighter more efficient. to me the 19" wheel is just looks too small for this large of a car. I prefer a 20" over something larger like a 21". I like having 2 sets of wheels since I have to deal with snow and mag chloride in the winter. You wont need to run a spacer anymore since the offset should be more flush w/o them. Do you want to try to spend time sourcing naked wheels and buying tires? or buying a set and selling the MX spec tires and buying new tires? refinishing wheels to desired color/condition. list goes on and on. Up to you what's worth it to your budget.

Thanks for the feedback. In hindsight, I wish I didn’t go through all this trouble with the spacers (I cut the front wheel studs so it can fit the 15mm spacers).

@SilverGS , sorry to hear about the blow out. It looks good low.

@BigDeep yes it’s been great. I liked using the staggered model X rims so much this summer that I’m now thinking of building a square set of all 4 model x “fronts”. Let’s talk if you’re interested in buying my staggered set of 2018 model X rims…but I would like to keep my Baolong gen 1 sensors because they were hard AF to track down a used set of.

Some pics of the 20x9 F with 15mm spacer and 20x10 R

This is exactly the rim setup I’m going for - though now I’m also considering adding a spacer on the front!

I can see you’ve got 245/40’s on the front - what do you have on the rears?

I’m considering 255/40’s (on 20x9) on the front and 285/40’s (on 20x10) on the rear.

Hey, folks. Please help. I picked up a set of four front model X wheels and put Bridgestones on them. 245/40/20. I didn’t want to have a staggered set. But there is pretty decent gap between the lip of the rims and the sidewalls. Obviously a wider tire would be more ideal but this size is the best for matching the overall diameter, and it seems like many people put this size on with no issue. I’m not sure if it’s because the Bridgestone are not quite as wide or the angle of the sidewall is not similar to other tires. At this point, I bought these tires at Costco and they are willing to let me exchange them for Michelins, but they don’t carry any other brands. Has anyone put Michelin Primacy or Pilot Sport AS4 tires on in this size? I attached a pic. Thanks.

@ViperGTS I think that’s normal. I plan on doing what you are doing/did (with that square setup) & exact same size tires.
The guy from Holland @PTMM is the OG & showed everyone that on this thread’s earlier pages about this a few years ago.
Let me know how that works for you but I think it should be fine?
I use that size on my fronts right now, (btw I have Kumho Ecsta’s) I just put them on for the summer…I’ve never had an issue.

Sizing varies from each manufacturer as it's not standardized. I have a set of Nittos on my Mustang that measure well wider than the exact same tire from Falken.
I haven't double checked the specs of your tires to verify, but I wouldn't be surprised if yours just run narrow.

you can go to tire rack find your tire and click the specs tab. Then compare each other manufacturers specs they all vary from tire to tire. For example, 245/40/20 potenza sport a has a tread width of 7.9" while a conti dws same size has 8.3"
