Out of Spec - Gravity vs Escalade

[momo3605]

I understand that aerodynamic drag is the biggest range eater at high speeds, and that the drag increases exponentially with speed. When driving our Air at sustained 80mph speeds on trips, we get about 78-79% of EPA range in dry, temperate weather, which I attribute mostly to the increase of aerodynamic drag at that speed.

What model/wheel size do you have for your Air?

Dream Edition Performance on 21" wheels.

Thank @hmp 10. I could not find tire infomation on the LucidMotors site. I still can't find where you found this.
Ah ha.... went there again and clicked on the very tiny + and found the info I was looking for:

Tire specifications: 265/45/R21 (Front / 285/40R22 (Rear) Michelin Primacy Tour A/S.

I want a large sidewall because the highways in PA are the worst in the nation.

My Genesis GV60Performance came with the Primacy Tour A/S tires. I hated them. I could just feel them letting loose around tight corners. I finally bit the bullet and replaced all four with Pilot Sport 4S tires and now the vehicle feels totally planted. The Primacy tires are good for wear and noise and the 4S tires are terrible on noise but if one cares about performance, the ultra performance tires are the way to go. It would be nice if the Gravity offered the ultra performance summer tires as an option for all sizes.

I was looking for information about the SIDEWALL of the tires... I'm looking to see the tallest sidewall, because the highways in Pennsylvania are all so full of holes, pits, cracks, and are constantly under construction and being resurfaced.

To me "Stealth" has a sinister connotation. I guess for lucid it means "cheap", the opposite of platinum.

So a person with a Stealth Air and a Stealth Gravity could say "I splurged on the Stealth Air ($1,750 more) and went cheap on the Stealth Gravity ($1k less).

Stranger: How much was your cheap Stealth Gravity? $121,700
Stranger: How much was a Platinum Gravity? $122,700
Stranger: Huh

That's the point I was trying to make on another thread about tires. By going with both staggered widths and diameters on all three wheel options, there are precious few options for summer performance tires on the Gravity.

According to Tire Rack, probably with the most comprehensive tire selection in the U.S., there are NO summer performance tires that will fit the 20/21" wheel package, and there is only one summer performance tire -- the Pirelli P Zero -- that will fit the 21/22" wheel size, at least if you want the "Y" speed rating on both axles. (You can go with the Michelin Pilot Sports if you'll accept a lower speed rating on the front axle.). Same with the 22/23" wheel size, but again with a speed rating mismatch on the axles. And the Pirellis for the rear axle cost almost $800 per tire for the 22" wheel and over $1000 per tire for the 23" wheel.

There are many fine performance tires on the market, but the Gravity's odd staggering makes only two of them usable, and even then not on the smallest wheel package.

You could get new rims. I bet Air rims will fit.

Order the Hankook wheels and then drive on them. If you hate them, get new rims and new tires. That's what I would do. But then I like the Hankooks.

My plan is to get base wheels and replace to winter tire, find light weight 22s and then go 265/285 Michelin 4S. None of that split diameter crap.
