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.

I was referring to the tire max pressure, not what Rivian says on the sticker.

Every tire has max load and pressure on the sidewall of the tire, along with the serial number that indicates the make date. These numbers are what the tire is designed to (before the safety factor is applied).

Oh ok. I have always was been told to follow what the car manufacturer states on the sticker. Not sure what’s right or wrong.

Came here to say this. I use 48 cold on 21" scorpions.

I'm on factory 20" ATs (15k miles) and keep my pressure at 50. So far wear has been light and even.

BTW, Discount Tire in my area fix flats for free, even if you didn't buy the tires there. They have done this twice for me. They have pucks and know how to work on Rivians. YMMV.

I run my R1S Gen 2 Pirelli Scorpion HL 275/50 R22 116H M+S @ 48 PSI cold.
