Setting Tire Pressure at Higher Elevations 

I'm not sure why they are promoting adding pressure for living in Denver because you would then be over-inflating your tire. Unless Honda pulled a major screw-up and put atmospheric sensors in their tires? I doubt that though. Gauge pressure and atmospheric pressure are two different units and gauge pressure is correct regardless of altitude or temp. if I measure my tire pressure at sea level and it reads 36psi and you measure your tire in Denver and it reads 36psi, both tires are filled correctly according to the mfg specs.. To say that one of those tires has a false pressure is simply not true. Put the recommended pressure in it and ignore this altitude compensation nonsense. The only time a tire will change pressure significantly would be if there is a BIG temperature change or BIG altitude change or there is a leak in the tire. So, unless you are driving from sea level to the top of Engineer Pass I wouldn't worry too much. Heck, you can see different pressures on tires that are in the sun versus tires on the opposite side that are in the shade.
