"The Definitive Firebird and Trans Am Guide 1967-1969" by Rocky Rotella shows the following installed numbers: 59,575 white line tires 14,672 fiberglass tires 16,068 red-line tires
It is a little confusing since the total '69 production is shown as 87,708. Why would there be 2,600 more sets of tires installed then cars made?
