The claims here seem dubious. They tested one type of brand new tire. Then they conclude that "high-quality" tires are somehow better without providing any evidence to support that claim. While tires may very well be a source of pollution I have to wonder where the money for the work came from.

Shitty tires start with the same tread depth, but wear out in 25-35k miles. High quality tires usually go 50-60k.

  Tread wear isn't a measure of quality, it's a measure of the how much 'grip' a tire is designed to have. High performance tires are softer to grip better, but wear out much much faster than tires designed for higher mileage. The higher mileage tires have worse performance characteristics - greater stopping distance, etc.

    High-performance tires also produce larger particles.

  The $400/corner tires on a sports car usually last about 5-8000 miles. They’re about as high quality as it gets.

    Tyres are designed on a performance - life continuum. High performance means softer rubber, with better grip, but thus lower life. Long life means harder rubber, with less grip, thusly reduced performance.

    I’m talking more the $60 on sale tires at pep boys.

  At least in the US, we have Uniform Tire Quality Grading [0]. According to Consumer Reports, which tested at least 47 tires, "most tires should live up to their mileage warranty claims"[1]. I've seen "high-quality" tires with a very low treadwear rating and I've seen "low-quality" or "cheap" tires with a very high treadwear rating. But the press release only mentions "high-quality" without defining "quality" at all. Which adds to the dubious nature of the claims.

  they're also measuring vastly more "emissions" over the life of the tire than there is material in the tires, so it appears that what they're actually measuring is the asphalt dust that's being created by the interaction between the road surface and the tire - a longer-wearing tire would presumably be harder material and cause slightly more road wear as a trade-off to less tire wear, so if they had actually tested it a higher-quality tire might cause more of what they're classing as emissions. but you can't really make an assumption either way when you've only measured on a sample size of one.
