Coefficient of friction and effects of

Click For Summary
SUMMARY

The discussion centers on the relationship between the coefficient of friction and tire wear, specifically focusing on a polyester and rubber tire with 7mm deep treads. It establishes that the typical coefficient of friction for road surfaces is approximately 0.7. The conversation highlights that while a truly rolling tire would experience no friction and thus no wear, actual tire wear is influenced by slippage and the material properties of the tire, complicating theoretical calculations. The consensus is that empirical testing would yield more straightforward results compared to complex theoretical models.

Not a question from a college course or anything like that, but one of interest to me:)

You take a car tyre made of polyester and rubber, the treads are cut to about 7mm deep, the roads coefficient of friction are normally about 0.7 in conjunction with contact of the tyre, if the weight is independent of the static friction between the tyre and road surface, how could a calculation be performed to work out how much wear takes place when a tyre rolls along the road surface?
 
Mathematics news on Phys.org
If the tyre were really "rolling", there would be NO friction and so no wear. In order that there be friction, there would have to be some slippage and the friction and wear would depend on the amount of slippage which is not given here.
 
I think it would also depend on the material of the tire itself - its "cohesiveness". I think the formula would be immensely complicated. That is, I think a theoretical analysis would be quite complicated. An a posteriori experimental result would naturally be much easier.
