Uh-huh... ever run over a slippery patch of ice or a puddle of water? Ever see your "speed" jump up and then back down? Relying on the speedo versus the tac is stupid. What happens when you put bigger wheels on your car? You are increasing the distance traveled now for every time that the axles turn once. That's now not relative to what your speed is (only off by at most, a 1/2 mph)... but at 155 mph, that's a lot of revs. What about those small donut tires people have (they look like go-kart tires)? Their top speed is knocked off? Why? Because the car is programmed to have the stock tires and knows the circumference/rotation ratio to figure out speed. Going by "wheel" or "flywheel" speed is unreliable. Going by RPM/gear is better. :P

The speed governor is usually located in the cars differential for RWD/4WD and located at the end of the gear box on FWD cars. This means it is measuring the 'true speed' of the car. Though that is only true if you keep the stock size rims (profile plays a role in it too).
The best way to overcome the speed limiters on cars is to remap the BCM (many people still know it as a ECU). Though if the car is older a chip will be an easier alternative, though if your involved in a crash due to high speeds, and the cops decide to investigate it is alot easier to find a chip (usually piggy backing off the BCM) then it is to search the coding on the BCM and find a few lines of coding amongst thousands of pages of coding.
I know some car insurance companies actually have special cover for club and track cars (or street cars used occasionally on the track). My insurance company is actually one of them. Though I live in Australia so I cannot say for sure that the States has it over there.
The reason I know this stuff, I used to be a mechanic, I am still a car enthusiast and I also race my car (which is heavily modified).
And the tyres you are talking about are known normally as track tyres. Used alot on drag cars for the higher torque situations. The wheels travel less distance on a higher RPM meaning the power of the car is utilised more (less loss from the flywheel to the rear wheels, or front wheels as it may be).

Not those... Like 10" rims they usually put on lowered 80's and 90's GTIs.

Why would you ever lower a GTI?
I am disappoint.

Because it looks cool? I think those mini donut rims/tires look retarded on everything except Japanese cars.
