'68 Charger R/T was STANDARD with "red streak" tires & "hub caps". The '68 hub cap doesn't have a red line, that was new for '69. Wheels with hub caps are the same color as the car in '68. Judging by the lack of OPTIONs, someone was shopping on a budget I'd bet silver wheels & hub caps when NEW! Followed closely by some "MAGS".
