Goodyear Assurance Tires

[cmoore99]

Anybody out there running these tires on there '04 or newer Sienna? If so what pressure do you run them at? The side wall says max inflation is like 45 psi. I have never inflated an automobile tire beyond 35. I think the door panel says to run the stock tires at 35 or maybe 32. The Assurances seem a little low at that psi. I figure if I can jack up the pressure a little I will get better gas mileage. I don't want to ruin the tires though. Thanks.

Have them on a Camry, run 32-35 psi.

Each tire has a max pressure at a max tire loading. If the loading is less the pressure can be dropped down.

If the tires are over inflated for the loading they can wear in the center. Use a low cost dial or digital caliper to check tread depth across the tire face and determine uneven wear before it ruins the tire.
