I have a set of 245 75R 16 tires on my C10. My speedometer says I am doing 42 MPH but I am really going 50 MPH.
I saw on one thread that some one riding 75's was saying it was throwing off his speedo.
Assuming it is tire and rim size causing my incorrect reading, I picked up a set of 15" nubbies.
I have searched out a hundred threads but can't seem to find anyone stating what size tire would make my speedometer show a closer to correct reading.
15" rims seem to have a limited options but was thinking maybe 235 70R may do. Anybody got the info?
