[Popman]

Do not under any circumstances follow the recommendation of the tire manufacturers who have spend untold resources testing and meeting government safety regulations for their tires put on your car.

You MUST diversify by inflating each tire to a different air pressure...or better use a different size tire all around so each size is represented when you drive.

[OrangeHoof]

Each tire should be inflated based on how it self-identified that day. A tire may feel like a front tire or a back tire or a spare tire. It is bigoted and hateful to misidentify a tire. Instead, always be sure to use the proper pronoun.
