I recently purchased a 2015 Expedition EL 4x4 with Hancook DynaPro ATM 275/55/20 tires. Door placard says to run 35psi. At 35psi they look low. Ford servince manager said they look low "but that is what Ford calls for". I contacted Hankook tech support and they said run 90% of max pressure = 45.9psi. (Max is 51psi) In the Florida heat i do not what to be under inflated. I am a 50/50 city/highway driver. Does anyone have experience with these tires on this vehicle and can you recommend a safe tire pressure? Thanks in advance
