It can get a whole lot better than that.Dang, 218 today, ready to see what I get with the hankooks
Are we sure psi doesn’t make a bigger difference than 1%?
I’m beating the long range model’s range with 20 inch summer tires
I did controlled testing at pressures from 38 psi through 50 psi in 4 psi increments. It certainly did make a difference from 38 to 50 but from 42 to 46 was indeed less than 1%.
Once you get to really high pressures the car becomes twitchy at speed. It just isn’t worth it at all.
