    Tire Pressure

    I now have a 2016(9.000 miles) and a 2017 both Grand touring(love them both) with 19" tires. Just wondering what air pressure others are running. I am not looking for a soft ride.

    Factory is a compromise

    Just the opposite. Lower pressure increases those dangers.

    Maybe that will balance out with the quicker outer wear during time I drive at lower than nominal pressure because I only add air every few months.

    Look on the side of the tires - the max. inflation pressure is listed there. Do NOT go any higher than that.

    You will also want to note the date code. Do not use any tires older than 6 years from the date code, no matter how much tread is left. This is also a safety issue.

    Date code is probably not an issue on a daily driver, but be sure you didn't pay for old tires.

    Inflation pressures can varied to influence vehicle handling (e.g. for racing); traction in sand, etc; and gas mileage. The manf. puts an optimal number on the sticker based on what their lawyers tell their engineers...

    I use the 36 psi on the door sticker for the factory wheels and tires. Why change?

    Yep, so does higher pressure. I didn't mention lower pressure because OP isn't asking about underinflating the tires.

    Not unless it's ridiculously high, too high to reasonably ride on. It's not an issue.

    Door sticker says 36lbs on the 19s.

    Iíve found 38-39 lbs to be the sweet spot on the stockers, currently riding on 38.
