35 PSI! I don't even drop that low when I'm off Roading.
The vehicle manufacturers and the tire companies spend hours working out tire pressures. Having a pressure lower than that recommended pressure could lead to shortened tire life and is a potential safety hazard. The air in the tire supports the vehicle, so less air causes the tire to increase in heat and work harder than it is supposed too.
The sidewall markings on the tire for inflation are tire industry standards based on size and usage. In other words they are regulations from the Government for Maximum inflation and load, they are not vehicle specific.
Plus if you read the sticker on the door with the tire pressures you will note it states, something like this vehicle conforms to all Applicable Federal Motor Vehicle Standards at the time of Manufacture.
Hence this is a Government Sticker (DoT) and should be adhered to.
Also a Tire Guy at Discount may look as a know nothing, but they train and get certified to do the Job.
I will keep running 65 psi all round loaded or empty, as recommended by Discount Tire and the DoT Stick not forgetting the tire manufacturers side wall pressure!!
