Is that referring to EVs? That number is surprising considering a tire only weighs ~25lbs. 9lbs/year means the tires are half-gone (and long since threadbare) in 5 years.
- steve_adams_86 2y agoMultiple sources suggest that 9 pounds is possible but on the very high end. It seems like something closer to 5 pounds is more usual. Being thread bare by 3-4 years seems common if you’re a relatively heavy commuter. I am surprised. I thought it was a lot less. I’m worried by this too, knowing so many people drive on their tires much longer.
- abdullahkhalids 2y agoIt is referring to the total from all four tires i.e. 4 kg per car per year [1]. Please note that car tires or anything really won't have uniform degradation. The first year will lose a lot of mass, then once the outer material is shed, there will be far less shedding [2]. So I understand the above number as global tire shedding in a year/total number of cars. P.S. I just looked it up. I have no idea if the source is reliable.
