So we are now nitpicking speedometer accuracy?
Utter bollocks. Wife unit has a brand new BMW and it's out by 4-5 KMH against speed cameras and satellite all the time.

lol
1. She bought a BMW.
2. How many speeding tickets has she gotten?
3. Kill yourself.
I do not need an accurate speedometer to know I’m at risk of getting a speeding ticket. If I’m traveling significantly faster than the regular flow of traffic, I’m at risk, if I’m only slightly faster, risk is reduced. If I am driving the flow of traffic I’m generally safe unless in Tennessee with out of state plates.
Only time I pay attention to speedometer is when I’m setting my cruise control.
Can't you get an app in the US that pings when you're approaching a camera?

then i'd say she has a shitty car. But its pretty common knowledge, and common sense that if change wheel diameter or gear ratio in the rear end, or even gear on the ends of the speedo cable, it will throw your speedometer accuracy off. And you can go even further to say change gear ratios within the trans that will also fuck with your speedo accuracy. All those things are what make up your speedometer readout. Not elevation or hills or any bullshit like that. Its determined by your driveline and your speedo is set specifically for your driveline's combination from the factory. If you fuck with that, it makes things go wonky.

Wheel diameter has nothing to do with it, I can roll 23's or 17's and still have the same speedometer reading
It's tire circumference that matters, how far does the car go every time the tire turns.
Taller tires go further so the speedometer will read lower.

I believe he was nitpicking on semantics. As in, it's not the wheel itself (the metal part you know) but rather the overall tire size.
