    I know there have been multiple discussions out there around over inflating tires on the Prius to maximize MPG, but I was wondering if anyone is running this tire, and if so, what pressure are you putting in? Recommended on my 2015 Persona is 32/33 front/rear (with stock 17" rubber), as I'm sure it is for many other Gen III models. I've inflated them all around to 39 PSI.

    Also, after dropping all corners with Tanabe springs and my wife driving around 1,000 miles on her winter tires/wheels, I've swapped them out with my new 18" TSW/Yoko set up so am ready to get an alignment. I've submitted a quote from my local dealership and will contact a solid independent garage in the morning.

    What's the pressure stamped on the tire's sidewall? I would think the larger tire would need more air. Higher inflation also improves handling and reduces wear.
