Hello,
I just got a new set of Cooper STT Pro 33/12.5/15 tires. What pressure should I run in these? I ran 35# in my Toyo Open Country MT and they wore very even. I have 35# in them right now. The tire shop filled them to 42. I changed that as soon as I got home to 35.
Thanks for the suggestions.

I ran 295/70R17 and kept them at 31 psi. I now run 315/70R17 and kept them about 32-33 psi. Do a chalk test to see where you should be.
 
Thanks
