Not to be an ass but why are you putting car tires on a truck?
It is the OEM spec tire, so is your question for Ram or the OP?
I run metric 115 load range now. LT E felt like it was too hard a carcass for the fire roads i run. Just felt very harsh, they were also grabber X3 which are a very heavy tire.
To meet the OEM GVWR (based on stock psi vs load index tables), inflation would need to be as follows:
P265/70/17 113 (stock p-metric) =40psi
265/70/17 115 (metric) = 34psi
LT265/70/17C 112 (LT metric) = 47psi
LT265/70/17E 121 (LT metric) = 47psi
All that said, OP, you should really consider an LT tire for your use.
