Bigger people are usually heavier and therefore will need alot more power to achieve equivalent speeds of smaller lighter people.
It is all to do with power to weight ratios and aerodynamics (wind resistance).
It does not change the actual speed of a vehicle but changing tire size can affect the accuracy of the speedometer.
The larger the tire the faster the vehicle will go for every revolution of the wheel.
The wheel size does affect its speed.

It affects you because you're an idiot.
Depending on the Issue If you switched tires recently or went to an alt size or even veh desc was lowered it could affect all those components P225/55R16 94H the speed rating or the size could affect your veh handling or components if going out of rec tire size or speed rating will affect the vehicle
It would affect its speed because the weight of the car is gonna slow it down
Changing the slope of the ramp will affect the speed of the vehicle going down it.
A heavy vehicle can go just as fast as a light vehicle, it just takes longer and more HP to reach desired speed with a heavier vehicle.
