My dealer replaced the Ps on my Luxury pkg with same size LT load Ds to try to fix my drivetrain problem. From the internet, it appears +15 psi is correct for the same load which would make them 45 psi. Dealer said 37 was more like it, so I was trying to see what the 285s on the Adventure pkg were set at. Not quite apples to apples tho because they have a higher load capacity at a lower tire pressure compared to 265s.
