2001 Infiniti QX4
Placard on car says 26 psi cold
Tires say 32-49
Rear tire is set to 27 cold
Does this look under-inflated? What’s the lowest I should go?

They may have originally specd lower pressure for ride comfort. I agree with using the tire’s minimum.

Why is everyone recommending the minimum here? I’ve always heard to go a smidge above the maximum for the fuel savings
If by maximum you mean the pressure recommendation by the car manufacturer, then yeah it will help with fuel saving. If by maximum you mean the pressure provided by the tyre manufacturer, please don’t do that lol. Jumping from 26psi to 32psi isn’t much, but jumping from 26psi to 49psi is way too much especially for car with only 1 passenger, it’s gonna wear the middle of the tyre without the weight pressing down to give it an even wear. The money you save here will be used to replace the tyre earlier than it should. Will also cause terrible braking.
