Засвар үйлчилгээний өртөг өндөртэй байсан Bugatti-гийн дугуйны технологи инженерчлэлийн дэвшлийн ачаар илүү боломжийн үнэтэй болжээ.
Bugatti Veyron загварыг бүтээх явцад 1000 гаруй морины хүчтэй, цагт 250 миль буюу 400 км/ц-ээс дээш хурдлах, бараг хоёр тонн жинтэй супер машины ачааллыг даах дугуй зах зээлд байгаагүй юм. Олон үйлдвэрлэгч энэ сорилтоос татгалзсан боловч Michelin компани уг төслийг хүлээж авснаар гар аргаар бүтээсэн, дөрвөн дугуй нь 42,000 ам.долларын үнэтэй инженерчлэлийн гайхамшиг болсон дугуйг гаргажээ. Гэвч уг дугуй нь хэт өндөр хурд болон төвөөс зугтаах хүчний улмаас ердөө 15 минут л аюулгүй ажиллах чадвартай байв. Түүнчлэн обудад тусгай цавуугаар бэхлэгддэг байсан тул дугуйг хоёр удаа солиход л обудыг бүтнээр нь соль шаардлага үүсч, Veyron-ийн засвар үйлчилгээг асар өндөр өртөгтэй болгож байв.
Харин Bugatti Chiron загварыг хөгжүүлэх явцад инженерүүд аюулгүй байдлыг алдагдуулахгүйгээр уг өндөр зардлыг бууруулахаар ажиллажээ. Прототип дугуйг туршихын тулд автомашины тоног төхөөрөмж хангалтгүй байсан тул онгоцны дугуй турших машиныг ашигласан байна. Michelin компанийн шинэчилсэн загвар нь Veyron-оос урд талдаа 14 хувь, хойд талдаа 12 хувь том хגригцэх талбайтай болж, бат бөх чанар болон барьц илүү сайжирсан юм.
Шинэ технологийн хамгийн гол дэвшил нь дугуйг ердийн обуд дээр суурилуулах боломжтой болгосноор обуд нь дугуй солих бүрт солигддог эд анги байхаа болиж, насан туршдаа ашиглагдах боломжтой болжээ. Үүний үр дүнд дугуй солих зардал эрс хямдарсан хэдий ч энгийн спорт машины дугуйтай харьцуулахад өндөр хэвээр байна. Chiron-ийн дугуй нь цагт 260 миль хурдлах үедээ ойролцоогоор 3800g хүртэлх ачааллыг ямар нэг эвдрэлгүйгээр тэсвэрлэхэд зориулагдсан нь инженерийн томоохон амжилт болжээ.

Bugatti tires once cost an eye-watering $42,000 per set, making them more expensive than many brand-new cars.
The incredible price tag wasn’t because of luxury branding, but because engineers had to overcome one of the biggest challenges in automotive history.
Building tires capable of surviving the incredible performance of the Bugatti Veyron pushed tire technology far beyond its limits.
Thankfully for Chiron owners, a complex engineering problem was eventually solved, making replacement tires significantly less expensive.
Bugatti tires used to cost $42,000
When Bugatti began developing the Veyron, it wasn’t just creating another supercar – it was building the fastest production car the world had ever seen.
With more than 1,000 horsepower, a top speed exceeding 250mph, and a weight of nearly two tons, the Veyron demanded something no existing tire could provide.
Bugatti reportedly approached several tire manufacturers asking them to create a tire capable of handling those immense forces, but most concluded it simply wasn’t possible.
Only Michelin agreed to take on the challenge and the result was an engineering marvel.
Every Veyron tire was painstakingly built by hand, with each set costing around $42,000, but even then, there were strict limitations.
At the Veyron’s top speed, the tires could reportedly withstand only around 15 minutes before heat buildup and enormous centrifugal forces made continued driving unsafe.
The tires were also bonded directly to the wheel using a special adhesive to ensure they remained securely sealed under the immense loads generated at high speed.
That created another expensive problem.
Because of the bonding process, each wheel could only accept two sets of tires before it had to be replaced entirely.
Considering the forged alloy wheels themselves cost tens of thousands of dollars, routine maintenance quickly became one of the most expensive parts of Veyron ownership.
Blame the Veyron, thank the Chiron
When it came time to develop the Bugatti Chiron, engineers were determined to eliminate the costly wheel replacement process without compromising safety.
To test prototype tires, Bugatti and Michelin even turned to an aircraft tire testing machine because conventional automotive equipment simply couldn’t spin the tires fast enough for realistic testing.
The final tire design delivered a 14 percent larger contact patch at the front and a 12 percent increase at the rear compared to the Veyron, improving grip while also increasing durability.
Most importantly, Michelin redesigned the tire to work with a conventional rim and standard mounting process.
That meant the wheel itself became a lifetime component rather than something that needed replacing after two tire changes.
The tires also became significantly more affordable to replace, although they’re still far from cheap compared to those fitted to ordinary performance cars.
Despite the lower replacement costs, the engineering is arguably even more impressive.
At around 260mph, the Chiron’s tires are subjected to forces of roughly 3,800g, yet they’re designed to withstand those extreme loads without failing.
Rather than being remembered simply for their astonishing price, Bugatti’s tires have become one of the best examples of how extraordinary engineering can solve problems that once seemed impossible.
