The age old tire pressure question (lemmy.world)

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?

would you be able to post a pic where it says the minimum psi on the tire? I work with tires and wheels and I have yet to see a tire with a range of psi like what you're describing and I'm curious to see.

I would set the pressure to what is listed on the placard.

usually with an 8 ply passenger tire, you shouldn't go below 20 psi.

oh also, the tire in the pic doesn't look under inflated to me, but looks can be deceiving
