It is technically "ok", but I would deflate the air to 35 psi. Reason being is it will ride rougher with more air in the tires, and it will wear the tread much faster. It will give you a little bit better gas mileage, but not to the point where it will break you even on tires. You can go to most local gas stations that have air stations and do it without having to go into the dealer. Just place the reader on the tire stem, and deflate it until it says 35. Hope this helps, and feel free to ask more questions.2015 QX60.
I realized that the recommended tire pressure is 35 psi, but the tire pressure of of the new QX60 is all 45psi.
Is it OK?
