None of that helps you explain your point and a lot of it is wrong.
There are several tire treads that are available in 4wd front and rear. With a little creativity with hex adapters, you could run equivalent 4wd fronts on the rear of a 2wd buggy, where I guarantee you will lose a significant amount of side bite compared to the rear of similar design. Hint - this is the same as adding weight.
Adding weight does not add traction. It increases pressure, which is not the same thing. Weight is the load that the available traction must manage. This is why there is a minimum weight in all powered sports and never a maximum weight.
The width of the tire does play a big role, but going narrower will result in less side bite. This is why with most cars, the wide tires go on the back (heavier + power), and the skinny tires go on the front (lighter+less/no power).
