I coded the car to display the temps. I won't be coding it out any time soon.

That's not it. All 4 tires are the same exact temp when I roll out of the garage every morning.

might be an alignment issue?

Cold tire pressure and the sun are both external factors that need to be taken into consideration. First, air up the tires the day before you check the pressure to about 40 psi. The next morning before the sun shines on the tires, let the air out to your prefered air pressure. I use 35 front and 36 rear with my stock staggered setup. If the sun shines on the tires or you drive the car before checking the pressure, the tires will 100% of the time have uneven pressure. Different air pressure means the tires heat up at different rates. Whatever the reason, (I think it is the auxiliary radiator) given all things equal the drivers side has a higher temperature which causes higher pressure. Now if I am driving in the afternoon with the sun shining on passenger side of the car, then that side has a higher temperature. If I'm hot dogging in the mountains, they all get HOT and the pressure goes way up.

The issue is not the sun. All four tires are at exactly the same pressure in my garage before I start driving. The difference in tire temperature occurs after driving 5 miles or so.
