Tires: tire size, gmc sprint, ss version
Questionwhat size tires came on a 1977 gmc sprint. we are redoing one and want the right tires
AnswerLinda,
I could not find any reference to a GMC Sprint in my tire books, but I understand that a GMC Sprint was the same as an El Camino - and if that is true, a 1977 came with GR78-15's or HR78-15's, except for the SS version which came with GR70-15's.
