I have the base P265/75-R16 tires on my 2009 H3 and the Door Jam Sticker for them call for 30 psi front and rear , and 35 psi for the spare. I think I may replace them with the LT285/75-R16 tires that come with the Adventure Package. Can someone with the Adventure Package and LT285/75-R16 tires tell me what the door jam sticker calls for the psi to be set at for the front/rear/and spare please ?

 

I run 285 tires on my base 06 H3 and the side of the doors says to run front and back tires at 35psi and the spare 50psi, hope that helps you.

 

I, too, have an 07 adventure package and stock 285 tires
I keep my four tires at 38 LB and the spare at 50 LB
When going off road on trails I bleed down to about 20 LB

 

My door on my adventure says 35psi cold tire pressure.

 

I have an '07 Adventure & have found if I run less than 38psi that I get TPM errors in cold weather. It also seems to run well on-road at that pressure.

 

Like I asked in the post, what does the door sticker call for ?

 

front and rear calls for 35 psi spare 50 psi

 

Who gives a ratt's butt what the door sticker says? The tire make stamps the pressure (range) on the sidewall. As has been said in 227071 posts, 38 PSI will avoid TPMS issues.

 

I have never seen the (range) of psi on a sidwall. Only the maximum cold psi allowed. Just wanted to know.

 

No, you can't use the tire sidewall pressures... tires of the same size can be used on a wide range of vehicles that can have substantial differences in weight.

The tire only lists the maximum limits; both for pressure and load range... there is no way a tire can tell you what to use for your specific vehicle. You wouldn't use the same pressure for a 5000lb vehicle as you would a 1000lb vehicle would you?

It is the same concept as an exercise ball, if you read the instructions they will indicate for a skinny 100lb girl to use a lower pressure than a large 250lb guy.

Typically you should always follow the sidewall pressure on the door jam. When changing tire size to something wider you can add even just a couple of pounds of pressure to change the tire contact patch back to stock.
