Road noise isn't just a driver aesthetic preference, it's a form of pollution that has direct impacts on human and animal health.
I could still be convinced that the sustainability or safety (from fewer blowouts) gains of these would outweigh that, but it's important to consider beings outside of the auto cabin.
- throwaway0a5e 5y agoRubber material properties (hardness basically) is a rounding error compared to tread design in terms of road noise and the dominant factor in terms of how long it takes the tire to wear down.
- tokai 5y agoDo you have any sources to back that up? All the literature I find is pointing to tire vibrations, which I would guess is a mix of material properties, tread design, and more.
- N1H1L 5y agoNot true absolutely. The rubber hardness is highly temperature dependent, and is modified by tinkering with your glass transition temperature. Winter tires have a lower glass transition temperature (are softer at lower temperatures), and as a result will wear down much, much faster in summer.
