Restoring a classic Mustang with period-correct tires can significantly enhance its authenticity and value. When selecting tires, it's crucial to choose those with appropriate accelerated weathering, which mimic the aging process of older rubber.

Additionally, correct pressure is vital. The original specs called for 26 psi in the front and 28 psi in the rear for 1965-68 models, and 28 psi all around for 1969-70 Mustangs. Inflating to these pressures ensures optimal performance and longevity for your vintage tires.

So, roll on over to your local Mustang meetup or online forum, and share your knowledge with fellow enthusiasts. Your insight might just help someone else get their classic ride back on the road.
