I run both 19” Slipstreams 3 months and 21” forged aluminum Arachnids 9 months.
The 21’s are stronger, lighter, provide sharper handling and increased curb appeal. These wheels are simply stunning. Tires cost more, high performance summers wear faster, and paying attention to curbs and road damage while in operation is a really good idea. I have never had a tire failure in three years.
The 19’s are quieter, handling is less responsive, tires are cheaper, last somewhat longer, (all seasons), and more options for replacement exist and are available. They are acceptable looking for a premium sedan and are not a problem. They tend to be quite common so ideal if you like less attention.
I put 21" Turbines on my car every summer. Wouldn't have it any other way. Wear is mostly dependent on your right foot, not wheel size, and tires are cheap. Enjoy the ride, I always say.
In the event any do get bent, they can be easily repaired/refinished. They're also pretty cheap to find spares. Due to not being able to pass up a good deal, I have four spare 21" Turbines in my garage in case of emergency.
The 21s fit the car nicely. I also like having spares and choices with 2 sets of arachnids and 2-1/2 sets of turbines. I don’t plan on buying new tires for a while, even with the extra wear.
I too have a brand new second set of Arachnids and tires, but am hoping to sell them; how did you get so many extra sets!?
Agreed on the fit and finish; these wheels really set the car apart; the Arachnids have the bonus of being a truly phenomenal wheel, with no range penalty over the 19’s and being stronger than any other offering. If you have a wheel failure it will likely be a turbine.
Are 21's the largest wheel that will fit our cars?
Some have found a way to run 22s, but there are usually drawbacks including tire rubbing. That’s why most people don’t even consider 22s.
Interesting because I found a post on reddit about someone who found 22" wheels without any rubbing and his S is lowered. He stated 22x9 ET 30 up front, 22x10.5 ET 38 out back. I'm curious if this works.
Ya, looks to be the same guy! Thanks for finding the post.Those are probably the Vossen wheels. Very nice looking and maybe one of the better 22 possibilities for the MS. Some drawbacks to consider would include cost, limited tire options, and durability. I would also research if there are different alignment requirements - not sure. Take a look at this post to get a better idea:
Show off your aftermarket wheels.

That's me. It does work. If you get tired of being cold in canada, come down to Texas and I'll show you!
There are no different alignment requirements for 19s vs 21s vs 22s. It just comes down to making sure your offset and tire size isn't so big that you run out of room in the fender well. But if you use my same tire sizes, the OD of my 22" wheels/tires is the same as the factory 21's, and the offset is about the same as well - just pop your 21's off and pop your 22's on.
I've found that many S's with the factory 21's rub, and it's because of the caster setting more than anything else. If you have rubbing with 21s or 22s within the factory tire OD, have an alignment shop adjust your caster and you'll never have a problem again.
Caster affects the position of the front wheel in the wheel well. It's adjusted on the front lower control arm, so you have a decent degree of room to eliminate rub in 99% of situations. My current Caster setting is +4.5 degrees on both sides, right within Tesla spec.
The only time my car rubs is when I'm taking a steep incline at an angle - and that's just because lowering means less suspension flex. But I have air suspension, so I just pop it back up to "very high" when making those entrances, and have no problems.
There are still a decent amount of tire options for 22's - I usually use Pirelli P-Zero Nero GT, but I'm trying ut Lexani's right now as a low cost option. The Vossens are a hybrid-forged wheel, so they're SUPER durable. Way more than the factory 21's. I've gone over holes that would crack a Tesla 21 and come across with no issues.
