Classic Firestone Indy Vintage Racing tires are produced in limited quantities, and are available to order only. They are perfect for classic Indy car restorations and are made in the USA, using new molds created from original Firestone designs. Tires are four-ply nylon casing. Firestone Indy tires are available in Blackwall (black sidewall), but paint pens exist to paint the letters and stripes as in the past.
