Straub Posted October 30, 2006 Share Posted October 30, 2006 What is your tire pressure and what tires are you using? Michelin P235/55R18 99V I drove my 400h home from the dealership on friday and checked the pressure, my front tires were 37 & 37.5 psi and my back tires were both at 38. I filled them all up to 38psi. I noticed the max tire pressure on the wall of the tire is 44 and the recommended tire pressure inside the drivers door is 30. Just curious what tires and psi other people are using and how they think it is affecting their mileage. I drove 300 highway miles home and was getting around 22mpg @ 75mph.
