Default Cooper STT Pro Tires LT315 /70 R17 121Q E2 RWL

Hello I finally pulled the trigger on 35's and I was wondering what PSI you all have been running them on the street. The local discount tire guys have recommended 40 psi which I think is pretty high for a 2 door relatively light weight wrangler. I already have them at 35psi and according to chalk test it is too high of a pressure. Should I go higher to what discount says or go lower? Is it weird because it is a Load E tire?

Thanks

I run those same tires, 30 psi works well for me on the road. Even wear for the first 4K miles.
