I recently bought an 85 Chevy Silverado with 32x11.50x15 tires on it, and the speedometer is NO WHERE NEAR correct...I was wondering if there was a calibration chart to punch in the numbers, and see what my actual speed was at...lets say...60 mph...is there any?!? I already looked at the TCI website, but I don't know what teeth are it it, and the axle ratio is, so thats not much of a help...I just what to know about how much it is off, so I don't get into any trouble
Thanks
