Tire size,rear end, and speedometer
So my speedometer is off by between 10-15 mph over 60mph. My tire size is 275/60/15 on all four corners and if I read right on another site that converts from original size to current I should only be about 1-2% off which unless i'm having a brain fart don't make sense as to why my speedo is so far off. So i'm wondering if someone in the past has changed out the gears in the rearend if that would make a difference and if so anybody have any idea what may be in it? Oh ya and it's in a 72 1/2 ton with 3 spd manual and sbc. Thanks for any help guys. I can't afford a gps speedo right now so I would like to figure out a cheap way to maybe get my speedo close to right.
