Both; with size comes weight.
Depends on the vehicle. It could improve mileage or lower mileage.
Of course not. It's a function of weight, engine size, driving habits, aerodynamics, etc...
The size of the engine can affect gas mileage. The larger engine produces more power and can use more fuel. The engine size alone does not determine what fuel mileage you will get though. Factors like how heavy the car, gear ratio used, proper maintenance and how aerodynamic the vehicle play a major role fuel mileage.
No, the effects are men on average are less intense that for women. This is because in part due to weight differences. Men on average are heavier than women, the large body size allows for more ethanol and it's byproducts to be distributed throughout the body. Which increases the amount of ethanol required to produce the effects of inebriation.
Requires more information, what size is the engine and is it an automatic or manual transmission?
more stuff has to be put on it to be able to support the weight
It's way too small, it's gas mileage is quite low considering the size and weight of the car. It's overpriced for an econobox.
The manufacture of your vehicle designed the tires to give the best ride, handling, mileage, and overall performance. Changing this tire size will effect one or more of these criteria. Improved mileage may come at a cost of lost performance. The engineers spent many hours deciding on the perfect size for this vehicle. My recommendation is to stick with the OEM size tire that the engineers designed for your vehicle.

No. THC stays in your system for 3 weeks regardless of your size or age. However, your size can effect how strongly and how quickly the THC effects you. Hence the term "light weight"
