2008 Prius with Ecopia Tires

Wassup?????

Costco set my PSI at 43. This is higher than what toyota recommends. Anyone gone up to 50?

I'm in southern ca so weather is not a common issue.

Finally got my 90 day MPG to 46. The struggle is real.

I run my 2008 w/EP422+ at 38-40. I personally would not go over sidewall pressure.

Not a recommendation, but I run most of my tires at 50 psi. This includes my winter tires that have a 35 psi max sidewall pressure... It doesn't seem to be an issue and I do not have abnormal tread wear at all.
