Will test to see if 50-55 psi works but not willing to go higher. If difference is negligible I will drop back to 45 cold. Will take time to test as I'm just getting a zero...first tank with new tires on the car. I use car computer to get a average of trip to from work. Minimize variables by taking same route. Wind rain ect. Out of my control but gives a good base read. Then will pump up a bit more. Granted I'm wary of anything over 50. Will have to test but roads I drive are a bit rough so Guessing 50 would be the high without additional discomfort in ride. Roughly 45 cold ATM recheck just the other day. Ride is very comfortable and quieter than the bald fuel max tires. Didn't lose my mind from road noise then so not severely concerned. If I can get 2% more fe from 5 psi I'll do it. Need to put American made back in top 10.
Current tank looking to finish around 54+ mpg. Little low ATM from pissroding it to test new tires lol. 46 mpg for first 130 miles. Just shy of 51 now at 212 miles.
