Also, this is why doing a wheelspin is never a good idea when you have trouble starting your car/train. The traction when the wheels are blocked but the engine tries to move them is always a lot better than when they're spinning in place.
- Gracana 12y agoTo be super-pedantic (because the topic is interesting), a little spin is good for an automobile. Rubber friction is a combination of adhesion, mechanical deformation, and wear.[1] In order to maximize traction with a tire you will have some optimal slip, increasing the "wear" component beyond what is seen in "normal" driving conditions. Of course, too much sliding/wheelspin and you reduce the other components. It's a balance that depends on rubber compounds, tire construction, and road conditions.
