KO3 tires installed on Rivian R1T!

I know it’s only been a day, but how does the road noise compare with the Scorpions?

Good question that I don't have a complete answer yet with only limited miles so far. Nice day yesterday with windows down during drive home. I can hear them but not as bad as I expected. I switched from 22s. My only reference with the AT scorpions was a loaner for a month during winter.

Those look fantastic! Nice work.

Will probably switch over to the same once the OEM pirellis wear out.

Lifting the R1T on 4 jacks seems a bit sketchy

KO3s installed yesterday. First time these have been installed at the Burien Discount Tire. These guys are great and I highly recommend. Special thanks to Chris and Patrick. They took special care to get it done right. Running at 65psi. I know I'll take an efficiency hit however the drive home looked very exceptable. Need more miles to fully understand the hit.

65 PSI? I have some Wildpeak AT3/W's on my truck, running 49 PSI but wondering if I should bump them up as well? max tire rating is 80 as well. Is there a noticeable benefit or issue running above factory (49) PSI?

Should really help.on those California winter trips to whole foods

Fastest way from Point A to Point B is a straight line. If that means driving over a parking block or a planter in the Mall parking lot the day before Christmas, you have to do what you have to do!!

Yeah I tend to agree...was a bit surprised. I confirmed they had worked on Rivians beforehand

I'm just getting ready for the creative parking required to access superchargers! Kinda sarcasm

Theoretically can be less rolling resistance so less reduction in efficiency for the beefier tires, but may ride harsher. Mostly I would look at wear to be the biggest indicator for your pressures if you are wanting to go over the recommended pressure (which of course is really only tested with, and most applicable to the OE tires). Look at the wear on your tires, if you are wearing the outsides more than the center increase the pressure, if you are wearing the center more than the edges reduce it. If you are rolling over to the sidewall you need more pressure too (or a less aggressive driving style).

Max psi is 80. 65 is the pressure that helps negate the efficiency hit per some of our friends on this forum. More of a personal test at this point and the ride so far is great

I’d think the opposite to be true. The higher the PSI the harder the tire and better efficiency. I always run a little lower than recommended to improve the ride quality at the expense of MPG.

Also did they use jack pucks?

You can use chalk to see if the tire contact patch is correct.

Yes- I confirmed ahead of time. They had already worked on numerous R1s

It's pretty common.
