Need some mentoring on how to convert Rpm to vehicle speed. I have a 53 3100 with a 54 truck engine and the 4.11 rear. I currently have 235/70/15 on all 4. I have tried the online converter posted here but no luck. I would like to know that at a RPM of 2000 what would my actual speed be. Thank you for you help.
