Gravity GT - small tire 0-60mph (for squeaks and giggles)

It's nearly fall and I'll be switching the Hankooks out for a 3PMSF rated A/S like Michelin CC2 or Vredestein Quatrac Pro for winter soon. I drive from sea level up to Tahoe a bunch so don't want/need a dedicated winter tire like Nokian or the Lucid approved Hankook i-Cept evo's.

I'll report back when I get the new meats on

I am using Michelin All Season 4. Work well
On everything but ice.
 
Hmmm...Love me some Michelins but I'm not seeing 265/50 R20 or 285/45 R21 as an available size for those Pilot Sport EV's on Tire Rack (I do see Cross Climate 2's...??) and aren't they a summer tire?

Also, the A/S 4's are NOT severe snow rated... so, WADR, in a 6000lb vehicle I'm not sure I'm comfortable going with a non 3PMSF rated tire over Carson Spur (elev. 8,290ft), Echo Summit (elev. 7,377ft), or even Donner Pass (elev. 7,227ft) etc.. when it's dumping. Catching the good powder means driving in that stuff, often the night before.
Tires matter!

Tires are most important. I’m in NYC so no crazy elevation. I had dedicated winter tires on the last car for peace of mind but never really had to push them.

Mine is a sports vehicle first so I need maximum dry and wet traction, all year long. Everything else is brief.
 
Michelin Pilot 4 SUV does exist for stock 20/21” at TireRack.

Have to search on size at a time.

Might be a decent summer replacement for the Hankooks

The problem here is it's 45* at 7am and 75* by 3pm so you gotta be careful in the morning on curvy roads w/ dedicated summer tires

Gravity won’t handle worse at 45F on dedicated summer tires vs hanflops
 
Agreed they're "just the tires that came on the car"...no way there's not a better choice out there

In my experience, there is always a stickier tire vs oem and I have replaced tires on all my cars within first month. We all need different things and traction is a priority for me.

Lucid does extensive testing to choose the OEM tires on its cars. They probably are, in fact, the best choice . . . but only the best choice for the specific goals Lucid was chasing for that particular wheel and trim level. And there's the rub for any manufacturer's OEM tire choice.

In the case of the Hankooks on the 21" wheels, it was efficiency above all else. In the case of the Michelin Primacy A/S, it seems to be low noise and all-season traction. In the case of the Pirellis, it was optimum warm-weather wet and dry control for aggressive driving (but something short of the limits that @037 probably routinely nudges).

I am nowhere near an ultimate performance nudger, but I always plan for worst case scenario as 828HP does not take very long to get you in trouble.

The EV tire is compromised by default with low rolling resistance, foam/quite ride, and sometimes just plain narrower than a tire of the same size brand and model that is not “EV” specific.

Even though I am generally nowhere near the limit of the tires I use, I like to know that I have a huge margin of safety in case I end up doing something I might regret, in the moment.

I agree with your comment on the Lucid 3 choices of tire, they accomplish their goals.

As far as maximum traction, that is where I come in. At least for the summer months. Someone else would have to push the envelope on the winter stuff as where I live a basic Michelin All Season 4 is enough, and both Lucid all season choices seem stronger in the snow. But…dry and wet they are nowhere near regardless of temperatures.

Just have to tailor to own preference and not worry about anyone else. I am here to share data, I don’t benefit from anyone using or not using something I mention.

Just be informed and understand your limitations:-)

This ^ is exactly how I feel every second I'm driving downhill around icy curves in the mountains

We fully agree no one tire handles everything
 
For those who like some inspo:)

Or ideas for tires, The Cayenne EV has PZero R EV summer tires, seems like a next level/gen...

I am trying to match Cayenne stopping distance on the next tire update, it’s running 295/325 and my 275/295 aren’t quite there, maybe 275/315 will do it as it’s a non EV specific tire with less weight.

We have similar concerns about traction in the snow, as I live up here in Tahoe City. I know that I could probably get better results by swapping rubber each spring and fall, but in recent years I've been running the CrossClimate 2 all year round. That's worked out well for me, but on a Highlander, which doesn't come anywhere close to the Gravity's power. Or its weight.
 
..one wonders what the CC2 would do with a 3 (US) ton 800+hp monster with regen shut off and RWS on them in real Sierra cement

what is the Highlander curb wt?
 
For giggles, here is my car on 22/23” custom tire.

I parked in standing water and launched through the water in the rain.

Forgot, I had 3x 84lb Lincoln Aviator black label wheels and tire in the back…

Posting this for those curious about the performance of the 22/23 OEM wheel/tire combination on a GGT 7-seater.

Quickest ET of the day was the first run and around 96% SoC @ 10.913. My fastest trap was 130.25MPH on the 3rd or 4th run.

@037 Can you share how turn-in and overall cornering feel/ability in the Gravity has changed since you've moved to the all-square setup?
