Tried 40 psi
well, the main reason i started this thread was to see if the max tire pressure would improve the stability of my yaris sedan on the highway. I just tried 40 psi (the sidewall of the tire says max is 40) and I noticed a BIG difference in stability at 75 mph...I am beginning to think that the main culprit in the yaris' poor highway stability is the very narrow wheelbase and that this can be compensated for by a strong/max sidewall on the tires - i think i am going to try 44 psi given that the max pressure found at the below link says 44:
