new tires and gears. vs. speedo

[ranger]

Ok i know if you change tire sizes you have to recal you speedo, and if you change gears with same tires you have to recal your speedo. If i get bigger tires and regear so that it is close to stock will i still have to change my speedo or does it even that out too

get it all installed and then see how close you are to stock. easily done on the freeway, just drive it at 60mph and measure the time between the mile markers. if it's 60 seconds to drive 1 mile, then you are dead on. a couple of seconds either way won't make enough difference to recalibrate, imho.

If you have a GPS that you use for travel, most will tell you your current speed. I used one to find out my speedo is about 5 mph low in the 50-60 range, and a bit more higher than that. Thats with 31's.
