Yes they are out by 5km/h (or more).

No why wrong/bother about it?

They are generally out by 5 to 7% so when the speedo says 105Kmh your actually doing a bit under 100Kmh. Best way to fix it I found was to fit 265/75 series tyres, these will make about a 5% difference on the speedo. As best as I can tell my speedo is just about spot on, or overeads by 1 or 2K at 100K at the most. I'd say mine was out by 7%.
