Toyo AT3 EV tires (285/70/r20) installed

[Dogger37]

Can you take a side profile pic of the truck so we can get a good look at the tires in medium height?

Thanks,
Donny

Medium height. I cut the tip off the stud

Those of you running on Toyo AT3s give an update on EV efficiency numbers please?

Yep
Overall diameter: ~ 2.1 inches taller (36.7” vs 34.6”)
• Sidewall height: ~ 0.56 inches taller per side
• Circumference: about 6% larger
• Speedometer impact: When your speedometer reads 60 mph, you’d actually be going about 63.6 mph with the 285/70R20 tires.

Just a correction on your numbers; they are 35.7 inches tall, so 1.1 inches taller than stock, not 2.1.
3.1% larger circumference.

AT 70 MPH displayed you'd be going 72.2 MPH. For efficiency calculations, you have to reduce 3.1% from the Toyo watt hours to compare versus stock. So Toyo tires around ~15Wh more efficient than the Cybertruck is displaying.

I ordered these as they tick all the boxes I'm looking for:

1. Decent off-road tread.
2. EV specific.
3. Slightly larger than OEM.
4. Definitely more aggressive look.
5. 3-Peak snow rated.

Doing some measurements, since they are just a hair over 1/2" sidewall height taller than OEM, you shouldn't have to cut the tip off the upper ball joint bolt or make any modifications.

You don't have to cut the tip but... If you off road with reduced pressure I would.

So just got these bad boys put on.. van charging Cybertruck for the 1.5 hour drive to the tire shop:

Off with the Pirelli's:

New S3xy:

Some random thoughts:
1. I was left with about a 3/8th's of an inch gap between the front tires and the bottom of the stock upper ball joint bolt. I'm comfortable with this but will double check any touching when I air down the tires for off-roading.
2. The tires are noticeably louder than the OEM Pirelli's, but not anything intrusive. I can hear the front tires much more than the rear for obvious reasons.
3. The truck looks WAY better with these tires.
4. I thought maybe they would be more comfortable of a ride having slightly over a half an inch more sidewall. But I think the stiffer/beefier sidewall for off-roading negates all that and the OEM Perelli's ride a little more comfortable.
5. I wasn't able to get any accurate energy use differences on the drive home as the wind was howling.
6. No rubbing even on the "low" suspension setting lock-to-lock.
7. Not a cheap install; doing the five tires including a full size spare, was right at $3,000. Actually had to pay a disposal fee for the Pirelli's with only 2K miles on them. I'm rural and didn't want to lug around four tires for the off-chance I'd be able to sell a Cybertruck specific tire set.
8. I'm glad that I can now off-road, but with comfort also high on my list after experiencing these 20" wheel/36" tires I'd probably lean towards aftermarket 18" wheels and making 37" tires fit with proper-offsets or small wheel spacers and slight wheel well mods.

I may drop the Toyo's pressure down to 45PSI to see if maybe I can get a little more flex out of them.

I’m glad you had a good result! I’m stilll super happy with mine and it’s great to see others weighing in. As it sits now, if I had to get new tires again tomorrow, I’d buy the same ones again for sure.

I see the Toyo and Tire rack show LT285/65/20’s available. Any specific reason the members are upsizing?

Larger tires are better for off-roading.
