Tires - Need some feedback

[JB.]

Tires look good.

They put the tire pressure at stock or 32 psi. They are rated to 65 psi, anyone no the proper PSI to run these at? Or can direct me where to find it?

32 is in the ballpark. From the standpoint of matching the load reserve of the stock tire, it would be about 34psi.

There's a load/inflation table linked in the red text.

Thanks, and if I am reading the charts right I should be at ~44-50psi..., right? Where's the 34 coming from? I.e.., all I am doing is drawing straight line over from C to LT line graph. Am I reading this wrong?

The charts are for illustrating the P and LT relationship, but could be used directly by 5th gen owners who go to LT but don't change tire dimensions. You have a 4th gen (marginally relevant) and also changed tire dimension (very relevant).

So, from the linked load/inflation table, using P265/65/17 as stock tire, load capacity at door sticker 32psi is about 2260. Then de-rated because it's P-metric on SUV makes it 2054.

LT285/70/17 load capacity at 35psi is 2105.
