so ive joined this forum to discuss this topic. IN class ive learned that wider tires does not give better traction and it is the same traction similar to a more narrow tire. now i have friends telling me that i am wrong bringing up that F1s do not use narrow tires because of traction. if someone can please clarify this to every instance that they can. if you would an could rebutal any of this please do. and tell me if i am wrong. thank you http://i19.photobucket.com/albums/b195/slim617/Book.jpg http://i19.photobucket.com/albums/b195/slim617/IMG_4870.jpg ...

Not only that but using car tires in a physics book is stupid (and something I've never actually seen before) simply because their coefficient can exceed 1, which changes everything. On top of that the standard equation does not account for deformation of the tire (which can be accounted ... Read Morefor through rolling resistance). Further more, even though the contact patch is the same regardless of tire size (generally) AT REST, the shape that it takes under dynamic load is better distributed by a slightly wider tire giving better traction. While a wider tire does gain some heat benefit from a greater surface area it's only a small part of it. Never trust your physics book for real world situations. Life doesn't involve frictionless surfaces and weightless ropes. about an hour ago · Delete Mark Giannini Also your argument of "it's for heat distribution" is stupid. If I am able to achieve a better coefficient of traction by keeping temperatures down through using a larger tire then I've still achieved more traction by using a larger tire.
