Emissions Analytics, an independent global testing and data company that studies real-world emissions and fuel efficiency for passenger and commercial vehicles, has found that pollution from tire wear can be 1,000 times worse than what comes out of a vehicle's exhaust pipe.

Unlike exhaust pollution, tire and brake pollution is mostly unregulated. These other types of pollutants from a vehicle are referred to as non-exhaust emissions (NEE). According to Emissions Analytics, NEEs are currently defined as "particles released into the air from brake wear, tyre wear, road surface wear and resuspension of road dust during on-road vehicle usage."

Emissions Analytics says that NEEs are believed to constitute the majority of primary particulate matter from road transport. The 2019 report "Non-Exhaust Emissions from Road Traffic" by the United Kingdom Government's Air Quality Expert Group recommended that NEEs be recognized as a major source of pollution.

To determine what the effect of NEEs are on the environment, Emission Analytics conducted initial tire wear testing. They used a hatchback running on new, properly inflated tires and found that the car emitted 5.8 grams per kilometer of particles.

Current exhaust emission limits in the U.K. are 4.5 milligrams per kilometer. That means that the team found that NEEs pollute the environment 1,000 times more than the maximum allowable exhaust amount.

Emissions Analytics noted, along with the results, that this number could be even higher if the vehicle's tires were under inflated or if the road surfaces were rougher.

Richard Lofthouse, Senior Researcher at Emissions Analytics expressed concern regarding the findings, "It's time to consider not just what comes out of a car's exhaust pipe but particle pollution from tyre and brake wear. Our initial tests reveal that there can be a shocking amount of particle pollution from tires – 1,000 times worse than emissions from a car's exhaust. What is even more frightening is that while exhaust emissions have been tightly regulated for many years, tyre wear is totally unregulated – and with the increasing growth in sales of heavier SUVs and battery-powered electric cars, non-exhaust emissions are a very serious problem."

There are ways to reduce the effect of NEEs coming from your vehicle, including making sure that your tires are properly inflated, and reduce the weight of your vehicle as much as possible (don't carry around excess weight).

Just a few weeks ago, Rolls-Royce showed off a Phantom that was created using materials and craftsmanship from fashion house Hermés. Fast forward to this week and Buggati has delivered something similar, but this one has a super sports car edge.

The one-of-a-kind Bugatti Chiron habillé par Hermès was crafted at the French luxury marque's Molsheim Atelier, combining the history of two hallmark members of the French fashion and automotive industry. It was made for Manny Khoshbin, a real estate investor-turned-influencer.

"I am a true Bugatti aficionado – I wanted to name my son 'Ettore' but my wife disagreed," said Khoshbin. "When I saw the Chiron1 for the first time in 2015, I was one of the first customers in the world to reserve a build slot, yet one of the later to take delivery of one, but the reason for that was down to me."

Khoshbin wanted to "defy the limits of custom automotive design" according to a media release, which prolonged the car's design and production phases.

The new Chiron features the intricate application of custom colors, fabrics, and finishes that required the expertise teams in Molsheim and Paris. The interior is finished in the leather shade of Craie (meaning chalk in English), which was made famous by Hermés handbags and other luxury goods. The off-white hue is matched to the exterior of the Chiron. The exterior color treatment extends to the rear bumper, mesh covers, trim bits, and the car's Bugatti Classique alloy wheels. Most Chiron models have two main colors that contrast.

The horseshoe grille on the Chiron has been customized to wear the Hermés signature "H" monogram while its Courbettes motif, graces the underside of the rear wing, which features a unique rearing horses design to emphasize the Chiron's 1,479 horsepower.

Khoshbin chose a Sky View glass roof for the vehicle that features two fixed glass panels above the driver and passenger seats.The exposed engine bay, Italian Red brake calipers, and aluminum-finish door sills are the only other exterior items not finished in Craie.

All materials used for the interior of the car have been crafted by Hermés from the seats to the console to the inner signature line, roof, door clasps, and rear panel. The Ecru leather around the centre console, dashboard and other parts of the interior, developed by Bugatti. The carpets are finished in the color Beige. The familiar Courbettes design finds another home in the car, this time on the console plate.

"The order of this special Chiron involved two visits to Hermès in Paris to discuss design, the realization of the interior and see progress being made," said Khoshbin. "Between myself, the team at Hermès and designers at Bugatti, we exchanged hundreds of emails. I took my time to draft the car and that was very much a conscious decision – this is a car that I will one day hand down to my son, it will live for generations".

"I'm truly thankful to the teams at Bugatti and Hermès for making this happen. I came to Bugatti with the idea, and it's not something that they'd usually do but they were open to the notion of making something special. Now I have three Bugatti models in my collection, and there is soon to be a fourth. There's this one, and two Veyrons, one a Grand Sport Vitesse "Les Légendes de Bugatti" Rembrandt Bugatti, that I love just to look at, they are so beautiful.

"Then we're about to take delivery of a Bugatti Baby II for my son," Mr. Khoshbin conitinues, "he is Bugatti mad, and gets excited every time he hears the name! I like the 'Chiron habillé par Hermès' the most out of them all – I drive it almost every day. It's a real driver's car and I still get excited every time I get into the driver's seat."

Khoshbin's affection for Hermés extends to other car brands as well. His YouTube channel shows off his customized, Hermés-themed Pagani Huayrai as well as others in his extraordinary collection.

New Goodyear WinterCommand Ultra tires provide the right amount of stopping power and stability on the road.

Testing vehicles is a great privilege and is also great fun, but having an opportunity to test a tire is almost better, as it brings the ability to dig deep on details and features from the comfort of my own vehicle. I was offered the opportunity to test the new Goodyear WinterCommand Ultra and jumped at the chance.

Before moving to Maine, I'd never given winter tires more than a passing thought, but they've quickly become an important part of my annual automotive maintenance schedule. So, before the weather warmed completely, I installed the Goodyears and got rolling.

Late winter and early spring here in Maine seem to drag on forever and can offer up weather that ranges from snow in the morning to deck-worthy sun in the afternoon. It's a tricky time of year to be a driver, because there are frequently times where tires can end up being drastically mismatched to changing conditions. This was the context in which I was able to test the new Goodyear WinterCommand Ultra.

A move to a new house and other challenges made it hard to coordinate a tire delivery, so the test was later in the season that I'd originally intended. In a way, I'm glad that the review took so long to come together, because it gave me the opportunity to try the tires in slushy snow, rain, and a warm sunny afternoon, all within the course of a couple of weeks.

It was 46 degrees and sunny the day I had the tires mounted to my 2015 Subaru Outback, and the first thing that stuck out was how quiet they are on the road. I usually rush to get the winter tires off once the snow slows down, because the tread patterns make a ton of noise on dry pavement. There's some noise here, to be fair, but far less of the typical winter tire "hum" than I've seen with the Bridgestone Blizzaks from winters past.

A couple of days after that blissful afternoon, the weather slipped back into a more typical cadence for March in Maine. Nearly eight inches of heavy, wet snow landed just in time for a run to kids' doctor appointments and an ill-timed shopping tip. We hit the road before the plows had been out in force, which meant inches of packed snow and slush. The Blizzaks I ran last season would feel planted and solid in these conditions, and surprisingly, the WinterCommand Ultras are nearly on that level.

We can debate whether or not winter tires are needed for all-wheel drive vehicles, but I'll always argue that winter tires are needed to improve stopping distance and traction on hills, and the WinterCommand Ultras did just that.

Of course, spring in Maine wouldn't be a thing without plenty of rain to make everything muddy. The Goodyears handled themselves well in the wet as well, and felt surprisingly confident in the near-freezing weather. There is no noticeable increase in hydroplaning or slipping under acceleration, and the tires retain their grip when driving quickly and cornering at higher speeds.

When it comes to pricing, the WinterCommand Ultras bring the value. Looking at Tire Rack, the Goodyears land at $171.92 per tire for my Subaru. Comparable Bridgestone Blizzaks start at around $180 and range up to $240 per tire. Michelins are also more expensive, starting at around $186 per tire. Though budget is important, price shouldn't be the only deciding factor when buying tires. In many cases, installation is free, and some tire shops offer free seasonal tire changes or tire storage.

The bottom line on the WinterCommand Ultra? It's a great tire for people who live in places that see varied weather in winter, especially if there are prolonged periods of dry weather. It's easily one of the quietest and most comfortable winter tires I've tested on dry pavement and it its snow/slush traction is lightyears ahead of even the best all-season tire. The Goodyears handled late-season Maine without complaint, and I suspect they'd be just fine in the thick of a nor'easter as well.
