Don't do much hauling except for a small boat once in a while. What is the proper tire pressure for my TOYO Open Country 37X12.50R20's?

 

id probably say 50psi

 

I looked on the Toyo website and could find no 37x12.50R20 in any of the Toyo open country (They are all named open country). There are 37x13.50 or 35x12.50, but no 37x12.50.

Please post back what is on the sidewall. Max weight and max pressure and load range B, C, D, or E. As the different tires were different load ranges including P series I need that info.

 

Oops, it is 37x13.5
Load range E

 

The Open Country M/T shows a fairly high max load at 65 psi. You should be able to run them at 40psi no problem. If you go lower, do not go below 35.

 

40 should ride the best. I'd try 45 but it may be pretty rough... I would consider 35 an absolute lowest.

 

Ok thanks for the responses. Been runnin at 36, but to play it safe I may jack it up to 40

 

Yea I would go up to at least 40 on that E range tire.

 

I've always had good luck with 40 psi.

 

You could always do the chalk test to check for improper wear as well. Chalk line across the footprint and roll forward on flat surface for 100 feet and inspect your line.
