2019 OWP Insight EX, 2021 PWP Insight EX
I've been running 40psi in both my '19 and '21 Insights. Tire wear has been normal with no ill effects. I'd mention increased tire pressures are not "recommended," as any deviation from normal can incur issues. For instance, higher pressures could affect handling and can make tires more vulnerable to blowout on pothole infested roads. Increasing pressures over manufacturer recommendations is done at your own risk. </legalstuff>What is the exact psi recommended then for increased mileage?
