2017 cherokee 23mk with205/75/14s china bombs. What should I set the low and high psi at? Tires say 50psi max inflate

[rsdata]

I set my 183 hybrid with tires inflated to 50 PSI
HI 58#
LO 45#

typically when towing the tires might get to 54# when they get hot, but I don't tow in TX in the summer either, where they may get a bit warmer and a bit higher pressure.

I will tow if the tires measure as low as 47-48# on the gauge and it was cool during the overnight, but I will air up if they are any lower than that.

I'd set HIGH to 60 - that's 20% higher than your desired inflation of 50 psi.

I think the recommended is 20% higher than max on the HI and 10% lower on the LO.
