I've got to drive my truck back home from the shop where it was lifted. Close to 120 miles, some interstate. New 35 inch SSRs. I am not going to be able to reset the speedo until I get back. is there a calculator on line somewhere that i can figure out what the speedo will read when I am actually doing 65?

HERE Is all you need to know Wade.

The first calculator on this page :read: No need to put in all that info when you dont need to.

It seems to calculate right. My speedo was off about 7-8MPH at that speed. I was reading 55 and doing about 62-63 I had my GPS with me to check it. and the GPS is right on the money so I know what I was going.

Thanks guys,

Let me get this straight. With a 3.73 and 35 inch tires I am going to be doing 120 mph at 3000 RPM. :jawdrop:
