20 inch Tire Pressure question
 
I just swapped out my Michelin Latitide Tour P265/60R18's that came with ORAII for Bridgestone Dueler Alenza P265/50R20's on these Black Rims. My question is, on the 18inch wheels the doorjam sticker in my GC says to inflate to 33 psi. What is the proper tire pressure for 20inch tires on my 14 GC? Can someone with original 20's check the doorjam sticker? :)

Helped my buddy pick up his Summit last night and checked the pressure -- door sticker said 36 psi.

I run my Forteras at 38 psi cold which gets them at 40-41 while cruising hot. No change I can see in wear characteristics and it doesn't hurt the fuel economy in the least. I average 16 mpg local rural driving and 20-21 hwy.

I have been running the Dueler Alenzas at 36psi (based on the input from everyone above) which seem to run around 39 when hot. I have been getting around 20.5 overall for my first two fill ups doing 50/50 highway/local, with about 450 miles on the odometer.

I run my Coopers much higher at 45 psi, I much prefer the feel of the steering given their larger width and they look better too. If I ran them at 36 they would look saggy.

I have Nexen 265/50/20 HP SUV. I run them at 40psi and they get up to 43-44psi when hot. The side wall says to inflate to 50psi. My first set of tires went 55k miles and currently on second set.

95% of my miles are highway miles and 40% of those miles are used on a windy road that goes from Palm Desert to Temecula. I drive on the fast side and taking the turns on this road is just fun.
