Basically weight plays a major factor when it comes to traction. The more weight the object has the more "grip" it requires to hold it. Even though more force is exerted to the ground, when cornering the downward force will change its direction according to the turn (not sure if you get what i mean there).
Just say a car takes a corner at its limit before any traction loss occurs is @ 50km/h, a bike could probably take it at 80km/h using the same amount of traction required by the car.
[There is a formula in physics that will tell u this but i can't remember it]
Also the more surface area the better, such as the more "tyre" on the ground is better. Although weight will also determine how much force will be put down. The more force in the same surface area, the more traction you will get. Just say like bike weighs 100kg (i actually dont know the real weight) and the surface area of the 2 tires touching the ground is 1m squared. A ratio can be thought of 100:1
On a car, the weight could be say 1000kg but the surface area by 4 tyres is 10m squared, so the ratio is the same 1000:10 -> 100:1
This means the traction is the same across both objects.
(Just trying to get the point across, these figures are probably wrong haha)
Wide tyres usually give more grip as it gives more surface area of the tyre touching the ground. (USUALLY not all the time)
Camber will increase cornering traction as the tyre wall will flex according to the corner. Just say u take a left turn, the tirewall will flex towards the right, and if the tyres have camber then it will conteract this flex and align the tyre to be as if it had no camber on the straight for the duration of the turn.

Not sure if you can understand this but i tried lol.
I might fix up this post later
