Regarding Smooth Hubcaps- They are made by mooneyes usa. Gto:

50 PSI on 44 PSI tires. IMHO what you might save in MPG by overinflating the tires will be lost when the center of the tires wear out prematurely
.
Overinflating also decreases the tire contact area making the vehicle more likely to hydroplane
on a wet surface. Not a problem if you live in Mojave.
On the other hand the yellow calipers will be good for at least 2+MPG increase
.
