Differences between the 19" and 20/21" Wheels on the same tire

[windscar911]

Main takeaway is that as long as you use the right tires, in every day(non-track) usage you lose very little performance by choosing the 19"s over the 21"s. In this video, around a track in the dry, there's about 1.5% difference in raw performance. Let's be honest, that's basically irrelevant on the Lucid Air.

What's interesting, what you stand to lose in performance (1.5%) is exactly what you gain in range on the 19"s
Just reaffirming more of what some of us already know.
(I have the 21"s on order, they're just so good looking)

Thanks for posting the video. I will stay with 19"s for my AGT and plan to fit Michelin PS4's in warmer weather and trust that the stopping distance will be better than 130' from 60-0 that was reported in a couple of road test reviews on the Pirelli All-Season tires from the factory. I favor the higher aspect ratio of the 19"s given the road surfaces in NE, but would have gone with the 21"s if they were forged wheels and if I could have been certain that winter compound tires, either Michelin or Pirelli would be available for this winter.

I think most of us choose the 21’s for the looks. Any alleged performance increase over the 19’s is secondary.

All I’ll say is I’ll launch on the 21s whenever. I will never launch on the 19s again, lol.

Yeah I've heard the stock tires on 19"s aren't amazing for grip. But with a more grippy summer compound it'll be totally fine.

any way to get 19" tires but change the wheels to make it better looking? not a car guy, so idk if there's compatibility issues

I believe there are many aftermarket 19" wheels that will fit. I haven't verified personally but many say that wheels that fit a Tesla Model S will fit a Lucid Air.
