- 2016 Buick LaCrosse 3.6 Premium
My new-to-me '16 LaCrosse came with Goodyear Eagle tires, and at 34K miles, seem to have good tread left. The door placard says 33 psi all around. On Saturday I aired them up to that and will get to the 60 psi for the spare shortly. But I'm curious: Do any of you increase or decrease the recommended psi, and if so, why? Does your practice boost your mpg or improve/degrade your ride quality?
