This guide is intended to provide assistance in utilizing load and inflation tables when replacing tires with optional tire sizes including “plus sizes” that may not be listed on the vehicle’s tire information placard (T.I.P.) or in the owner’s manual. For inflation pressure recommendations for the original equipment (OE) size, refer to the tire information placard (T.I.P.) or owner’s manual. The T.I.P. is commonly found on the vehicle door edge, door jam, glove-box door, or inside of the trunk lid. For more information on the proper selection of replacement tires, refer to our tire safety section on our website, www.toyotires.com.
