Stupid question?? but aren't all 6 of them suppose to be around 120? Why are the 2 inside back axle tires so low? Any ideas and should I just inflate them all to 120? Thank-you and please don't laugh...  |
The sticker inside will give the recommended tire pressures... May be the same all around... May be different for front vs rear... Personally never seen difference for inner/outer on a dual...
You can certainly run the stated pressure up to the vehicles max weight as Murph suggested.
Some try to 'tune' the ride - if you are not at max weight - you may get a softer ride running a lower pressure. To do so safely you need to know the weight of the rig as you would have it loaded - at least axle weights (I haven't found a place that does 4 corners near me).
Based on weight and manufacturers tire chart, you can see the required pressure.
