Tire Pressure Recommendation for Winter Tires

[Pedro504]

Used Tire Pressure Calculator on Tire Pressure Calculator to determine the recommended air pressure for my new Blizzak P265/65 R18 tires.
Because the 18s are significantly different than the oem 21s I'm looking for the best pressure to run the new Blizzaks.
The Tire Pressure Calculator appears to be basing it's recommendations using a Load Capacity priority and it's recommendation of 26 psi seems too low for actual use conditions. Currently I'm running 31 psi (cold). Any thoughts or recommendations?

I have always run the same tire pressures in my winter tires as the ones recommended in my OEM tires even when the winters were a different size.
This is the first time a different PSI has been brought up as far as I know.

On my previous cars with different wheel sizes that can come standard, the smaller wheels do have slightly lower recommended tire pressures but 26psi is quite different from 33psi. I tend to run my winter tires 255/65/18 at 35psi. I believe if you had the base explorer with 18" rims, the 255/65/18 tires are recommended at 33psi, same as the 20" and 21" rims.

I have a 2020 xlt and have some aftermarket wheels with General altimax snow tires on them. I can get you the size when the explorer gets home. I also run at oem psi, ~33-35 however I have to check as when it gets cold we lose some pressure.

26 is way too low. Run the stock pressure, or at least 30.

Thanks for the feedback. Decided to run 33psi, the recommeded pressure for the oem tires. I'll report back in the spring when the Blizzaks come off.
