What’s your tire PSI?

[tate16t]

For 2023 Rivian’s running 22" Sport Dark HL275/50R22 116H XL Pirelli Scorpion Zero All-Season, what is your PSI set to? The label on the vehicle says 48 cold, is that what you use? If not, what has been your experience either way?

Both times after I've had a service call I noticed the screen showed 52 psi right after I started driving...so "cold" measurement. Since that's what the techs seem to use....that's what I've been using (22" original Scorpions).

After my last mobile visit a few months ago I noticed they set mine to 52-53 cold. I just set it to 48 cold and it seems smoother to me. It could be all in my head though.

I recall that the OE Pirelli had cold max inflation as 51 PSI. I would double check the tire max pressure and no exceed the PSI.

I am now running Michelin Defender 275/50/22 115 on 2023 R1S, and os set at 48 PSI in fronts and 47 PSI on rears.

While over inflated tires reduces rolling resistance, it will result in uneven tire wear.

The OE Pirelli‘s cold is 48.

47 - 52 PSI. Altitude and definition of "Cold" make a difference. We have two houses, only 160 miles apart driving, but over a mile difference in altitude. So, I keep 22s at 47-48 when at 6800 ft and cooler temps. But when we drive to the lower altitude house goes to about 52 PSI due to 20% more outside air pressure and hotter "cold" temps.
