2016~2023 18 inch wheel tire pressure

[youri]

For those that have the stock 18inch wheels on gen 2, what is the tire pressure rating for them? I downsize from 20 to 18 in winter. For now i have been going with the 20 inch tire pressure requirement marked in the driver door sil, but curious to see if it is different for the 18 inches.

Probably doesn’t help much, but the 4Runner has the same PSI rating on both the 20” and 17” wheels

Wheel diameter doesn't matter. Go with what the door tag says, as it is based on the vehicle and its weight.

According to the napleton mazda website the psi for 18 inch wheels is 36 psi.

That’s my train of thought but wanted to confirm.

According to the napleton mazda website the psi for 18 inch wheels is 36 psi.

My 20 inch pressure requirement is 34 psi, so if that is accurate the 18 inch would be 2 psi more. Ideally someone with oem 18 inch can confirm.
