Suggested Tire Pressure

[FLtahoe]

What is the suggested tire pressure for a set of 275/55/20s? And is this cold or hot?

Cold = pressure first thing in the morning.
Hot = after you've been driving a while and the air warms up.

I ask because the previous tires were for 17s and the suggested tire pressure of 32 lbs was based on that tire. I was wondering if the suggested tire pressure would change if the wheels were bigger?

the 18's cold. check out firestonecompleteautocare.com

@Kondriac - Thanks. Good site.

@1lohoe04 - 40? really? I don't think I've ever rode anything close to that. I'm interested in how it would ride...

Do as we did. Try and monitor tire wear and if everything stays good they you will know. I found it was much more stable and got rid of a minor vibration i had. I have put 12000 km on them and the tire wear is good.
