Tire size
I am currenty running 265/75R16 on my 1968 C-20
The speedo reads 50mph, and the GPS says 55mph I am switching to 9.5x16.5 tires to go on my original steelies that I found. According to tire charts, they will be aprox. 1" shorter (30.5 vs 31.5) Is there a way to calculate if this will be closer to correct? And how much this will affect RPM? I have a turbo 400 and 4.10 gears. |
