Just buy a satnav and use that to check your speed and either write down on a bit of paper stuck to the dash or mark the speedo wiv tippex.

wonder why they ask you to measure the radius of the tyre, as well as it's circumference?

Gps is never slower. I think you'll find that your speedo is recording 4mph faster?

A GPS takes a fix from several satellites in order for it to figure out what it's position and altitude is. it repeats this process at a fixed interval. (lets say every 5 seconds) by working out how far it has travelled in those 5 seconds. (Say it's 147yards,) then the GPS then knows that it's travelling at 60mph. So it's never wrong. Whereas a speedo rarely shows the correct speed.

I've just got a wee laminated sticker on me dash giving the actual speeds I'm travelling when me speedo reads 30, 40, 50 etc. With RR diffs & 235/85s the conversion factor on me III is about 1 : 1.46. It's a piece of **** to read & you soon remember what's what.
