Does anyone know if these will fit a 75 Monza? It originally came with a BR78-13 and I can't even find the dimensions on that size today. Searched numerous times on the internet.

The quick answer is yes they will fit.
B78-13=P175/75R13 or P185/70R13
The B78-13 converts to the either a P175/75R13 or a P185/70R13. The 175/75R13 will be a narrower and taller side wall than the 185/70R13. The first number is the width of the tread in mm and the second number is the aspect ratio or height of the side wall and the R stands for radial and the last number is the rim size 13".

So the tires everyone is talking about in this thread is the BFG RWL 205/60R13's which would be about 20 mm wider than the stock tire and since the aspect ratio is 60 it would also have a shorter side wall.

Ya, that's a good one, it even gives you the speedometer error amount. Cool, thanks for that.

New 205/60R13 T/A Radials (from Coker) on my new-to-me '76 Cosworth:

The car had 18 year old Firestone Firehawks on it when I purchased it. They were a bit "lumpy." :D
