What tire PSI should I run?

I like that chalk test I am going to do it as soon as it quits raining. I am at 35 on all four now. With 245/75R16 load range E.

 

That last sentence made my morning! Why else would we be on this site Great thread and using the above I can now tell my tires are over inflated. Not sure if it has anything to do with my new UCA's and coil overs, but gives me a reason to tell the wife that I need new tires. My Nitto's didn't last as long as I thought (maybe due to the over inflation??). Only got about 23K out of them and they are getting a bit scary in the rain. This could be a side effect of the S/C

 

Are you sure is right?

 

Stock size? run what it says on the door jamb. Oversized? Use this load inflation chart.

 

+1

I've noticed a lot of people assume you can run similar -- or lower -- pressure with an LT metric compared to a P metric. Not so.

 

I had planned on lift and bigger tires, but stupid costco won't put anything other than stock tires on a vehicle because of liability, and all I'm really doing is adding cost and reducing mpgs. If I offroaded more I would be willing to pay, but oh well.

Also I don't care about the ride quality. I like to keep the tires aired up pretty high and get longer life and better economy.

 

Hi all.

Stock Dunlops.
I set all 4 to 30 # as per the door plate, set the TPWS, then set them (and the spare) to the 40 # I run them at (they are 51 # max as per the sidewall).

Cheers
Ray.
