My old eyes...or these pix lol... I think the backs are Firestone Drag Copies made by Coker.... and i do believe the fronts are BF Goodrich
Silvertown copies, also made by Coker
Not quite right im sure.... I can tell you from experience those back drags (Firestone copies) are just for looks, they weight more than a truck tire!!!
At first i was thinking M&H slicks on the back, but Summit's pix aren't accurate i do believe.
