- yes, lots.
-
- you need to know the characteristics of the tire compound,
- the weight/load on the tire from the car (and its operation),
- the inflation of the tires, and so forth.
-
- i think that it will prove to be too complicated a computation
- to be worth trying to do, unless you happen to work for a tire
- company and have the necessary resources.
-
- trust the speed rating, and keep your tires properly inflated.
