Tire age
If you don’t know how to read (inspect) and care for tires especially on low use vehicles than yes you better just rely on the tire shop and born on date of the tires. Tires mounted on a car that sits outside baking in the sun, exposed to the elements sitting in one spot for extended periods with possible pressure loss is not the same as ones either covered, rotated occasionally (varying contact patch) stored indoors, at correct air pressure etc.
Stop with the Theory fear mongering:rolleyes:
