Exceeding past the manufacturer's max load cold tire pressure recommendation will lead to a smaller contact patch with excessive wear in the center of your tire . It will affect handling characteristics and braking distance which is unsafe. You're compounding the risk of a blowout being in a heavy SUV.

Not worth the risk to the safety of yourself, passengers and others on the road, just to save on a few gallons of gas IMO.
When I stated manufacturer, I should have specified car manufacturer (Lexus) recommends as best tire pressure for optimum ride comfort.

Believe you'd still have to exceed the tire manfacturer rating pretty far to see a significantly smaller contact patch. Todays tires stiffen the sidewalls (versus bubble out days of old). Agree the blowout risk increases significantly, but I think handling and braking wouldn't be affected too much with todays tires. Ride quality would be horrible though. Agree that none of it is worth it though. Especially in a city like NY with our huge potholes.
