Nothing to add as far as Rivian goes (yet), but I ran KO2's on my previous truck for a decade. Three sets, lasted around 50k miles each (ballpark), the tires would crack and start dryrotting before the tread would wear out. Loved them.

Am *very* interested to try them on the Riv when the time comes. Any concerns about load rating?

R1T and Model 3
I know these are E rated and all, but how does it handle the 7200 lb weight and 835 HP of the R1T?
- Any loss of turn in feel or grip when accelerating hard?
- Do you feel more or less sidewall squish?

Just trying to gauge how much tires may be modified for the application here with these Scorpions.

Hey! Do these vibrate your steering wheel at all? I have same tires on my R1T and my steering wheel shakes at high speeds 60-70MPH.
no vibrations for me up to 111. They’re AT tires, and they feel like AT tires- very similar to how this tire has felt/sounded/performed on other vehicles for me. No regrets after 1k miles for me. If you want quiet and perfect road handling manners these are not the tires to buy. If you want something to unleash the beast, these are a great choice. A couple of quick photos, including mine parked next to a silver R1S on 22s that I ran into yesterday. I stopped to give them a Matchbox R1T. I was still in high after parking next to a Jeep at my last stop…

Quick BFG KO2 tire update after a quick 400 mile down and back trip on the highway yesterday. Range was about as expected and ride was about as expected. And traction on a muddy jobsite was just as expected as well. 1700 miles, no regrets for me.

Thanks for the update (and sorry I only just saw it). When you say your range on these is about as expected, can you clarify what you were expecting? Slightly better / slightly worse / about the same as the ~274 miles anticipated with the stock 20" Scorpion ATs?

I just had a set of KO3 tires put on . . . The look great, ride is a little worse and range a touch less but I'm hoping the traction off-pavement and in snow/ice is way better!

can you comment on what a touch less range is over a full charge? do you think its <5% or >5% impact? eyeing these as well for offroading, have you had a chance to take them out yet?

I think I need more time as it's only been 3 days and driving style dictates so much. My guess is that it is definitely <5% vs scorpion AT

Quick update after 5k miles- pure beast mode. They air down great to 25 psi. I run them at 58 psi cold, which is about 60 at night in this heat. They had no problem in 4 feet of water yesterday and then after airing back up running like a dream. (Granted, my fellow Rivian friends with Pirelli 20s had zero issues in 4 feet of water either, but I still love these tires)

I'm also curious. My stock scorpions have gotten really loud, so I'm looking for a replacement.
Noise started to get loud at what mileage?

Thanks for posting. I just got my deflators in the mail and was planning to do a chalk test tonight. I’ve kept mine at 60 psi with about 1k miles on them. While I’m playing with the deflators I thought I might as well test the 60psi, which feels great.

Awesome, what's your hitch set up?
