25
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?
I would 1)go with the vehicle placard as the default and and limit driving until I 2)call a reputable dealership
I think it was the Ford Explorer that required lower tire pressure because the vehicle was a rollover threat at normal inflation pressures. But people were worried that the tires would blow out if under inflated. There were a ton of lawsuits.
They did a 60 minutes piece about Jeeps on this too.
It was a mess.
Damn. I feel like 26 is pretty low. Some old threads about R50’s said they had a TSB raising it to 30 so that’s where I’m at now. Dealership said follow placard but the car is so old they don’t know or care
