18in rims with low rubber on a '67 classic!@!@!@!@! No offence Pain, but no...
luisloja,
the '67 6 Cly and 289 came with 14x5 rims
the '67 390 and GT came with 14x6 rims
the Shelby came with 15x6 or optional 15x7 rims
So, tires...
I am going to asume this isn't a Shelby or the 390 or you wouldn't be asking this question here
If you have the 14x5s
The standard tire size was 695-14s and the optional was 735-14s
The conversion in today's tires would be (for the 75 Series) P185/75R14 or P195/75R14 and (for the 70 Series) P195/70R14 or P205/70R14
If you have a GT with the 14x6s
The standard tire size was F70-14
The conversion in today's tires would be (for the 75 Series) P205/75R14 and (for the 70 Series) P215/70R14
Tires were almost always BFGs
