Easy solution: Use longer lasting tires like 50k tires rather than 30k tires and FIX THE ROADS so there is less wear. Roads in Los Angeles for example are absolutely horrible.

And we have emission laws here that aren't enforced. Tons of illegal exhausts and mods and NOTHING is done. Cops ignore it. I've seen so many smoking cars as well.

Also, road wear is a function of friction as well as pressure. Friction is increased with additional tires.

This is already taken in to account with the forth power rule, isn't it?

Fourth :)

I thought brake pads use asbestos which contribute to the noxious particles. I do think Vehicle-to-vehicle communications will eventually minimize the all the chicken necking, evening out the traffic and thus less breaking.

Brake pads have not used asbestos in several decades.

Unfortunately, I do not believe that this is true. My understanding is that it's still quite common, and even more so in developing countries.

They're torn up from the road and rubbed off from the tyres themselves. The majority is obviously coming from the road. There's been studies done here in Sweden since we've banned studded winter tyres in some areas of Stockholm in an effort to reduce road wear and improve air quality. I don't know of any sources in English off the top of my head though. The last time I read an article about it though (2+ years ago, d…

>They're torn up from the road and rubbed off from the tyres themselves. The majority is obviously coming from the road. Not sure even that adds up to believable. The Sydney Harbour Bridge is about 500m long between the pylons. It has "more than 150,000 cars per day" on it (according to the snippet from a google search). If all of that was from the road, that'd mean there's about 160 tons of road getting torn up per…

It might be due to different tires. People in Sydney are very unlikely to be driving tires designed for ice and snow.

Yes. A high UTQG rating will mean your tires will last forever at the expense of traction, road noise, etc. The last set of tires I bought at Costco lasted 70k miles, but also increased wet stopping distance and introduced a roar to cabin noise. My latest set have a UTQG near 0 and will only last about 10k miles but they make no noise and have insane amounts of grip (think race car tire)

If you drive less and have separate summer/winter tires, it has the odd side-effect of making long-wear tires not worthwhile, as the life of the tread depth will exceed the life of the rubber due to age.

I drive about 3.5k miles a year, the OEM tires would have given me 70k miles but I would have never got there. the michelin pilot sport 4s where $5 more per tire and would survive just about 7 years (i'm planning 3-4 with the occasional track day). the tradeoff was DEFINITELY worth it, but now i'm deathly afraid of potholes and road hazards lol!

(after 1000 miles on the MP4S you're already more than 1/16th worn and would need to replace the entire set to keep the AWD system happy)
