O'zgartirilgan g'ildirak uyasining asosiy parametrlari:
1. Jant kengligi: odatda 5,5J, 6J, 7J da ifodalanadi va birlik dyuymdir. Odatda, shinalar kengligi 185 bo'lgan shinalar uchun 5 dyuymli jant kengligi kerak, 195 uchun 6 dyuym, 205 uchun 6,5 dyuym va 215 shinalar kengligi 7 dyuymli jantlarga mos kelishi kerak.
2. G'ildirak diametri: 12, 13, 14, 15 va boshqa xususiyatlar mavjud va birlik dyuym. Hozirgi vaqtda bozorda Infiniti FX35, BMW X5 va boshqalar kabi 20 dyuymli g'ildirak jantlariga ega modellar mavjud.
3. PCD value: that is, the diameter of the circle formed by the tire screw, in mm, domestic cars are usually 100, 114.3, European cars are more special, including 98 of the Love Express series, 108 of Volvo, 120 of BMW and M. Benz's 112.
4. Markaz teshigi: Jantning geometrik markazi markazning geometrik markaziga mos kelishini ta'minlash uchun ishlatiladi, shuning uchun avtomobil yuqori tezlikda ishlayotganida rul chayqalmaydi.
5. Geometrik markaz chizig'i: Jantning eng muhim mos yozuvlar ma'lumotlari, shu jumladan Ofset qiymatini, qanotdan aniq masofani va boshqalarni hisoblash ushbu qiymatga tegishli bo'lishi kerak.
6.Ofset: G'ildirak uyasining sobit yuzasi va geometrik markaz chizig'i orasidagi masofa, uning eng muhim roli shinaning avtomobil tanasiga eskirmasligini ta'minlashdir.
7. Jant devori: shinalar tagini qo'llab-quvvatlash va yo'l yuzasidan zarbani yutish uchun ishlatiladi.
8. Jant yelkasi: shinalar boncuklari bilan chambarchas bog'langan, shinalar bosimini oshirish uchun yaxshi havo o'tkazmasligini ta'minlaydi.
9. G'ildirak diskining yuzasi: ba'zi jantlarning tirnoqlari disk yuzasining vertikal chizig'idan tashqariga chiqadi, shuning uchun jant shinalar tomonidan himoyalana olmaydi va ozgina ehtiyotsizlik bilan to'xtash jant sirtining qoplamasiga zarar etkazishi mumkin.
10.X masofa: Ko'p-porshenli kaliperni o'zgartirishda e'tiborga olinishi kerak bo'lgan ma'lumotlar, aks holda jantning disk yuzasi va tormoz kaliperi o'rtasida ishqalanish bo'lishi mumkin.
Shinaning yon devoriga shinaning turi, tagligi, o'lchagichi, trubkasi yoki yo'qligi, tezlik darajasi, yuk ko'rsatkichi, tomonlar nisbati va muhim xavfsizlik belgilari kabi ko'plab foydali ma'lumotlar joylashtirilgan. Ushbu qism haqida ma'lumot olish uchun shinalar diagrammasidagi istalgan qismni bosing.

Misol: P215/65R15 89H
"P" refers to passenger car tires. (Used to distinguish tires suitable for trucks or other models)
"215" refers to the width of the tire section, which is the width (in millimeters) between the two sidewalls. This width varies with the rim width to which the tire is matched: wide rims with wide tires, narrow rims with narrow tires. The tire width generally indicated on the sidewall refers to the width when the tire is mounted on a rim of the recommended width.
"65" is the aspect ratio of the tire, which is the ratio of the tire width to the tire height. Here, the tire height accounts for 65 percent of the tire width. The smaller the value, the more flat it is.
"R" refers to the structure of the tire, indicating that the tire is a radial structure, that is to say, its ply is arranged in the carcass in an auxiliary radial shape. "B" indicates that the tire is of a bias structure. At present, the car tire with a bias structure no longer exists.
"15" means the diameter of the rim (in inches), this tire must match the rim of 15 inches, otherwise it cannot be installed.
"89" indicates the load index: the maximum load capacity of this tire is 1,279 pounds. Different load indices represent different maximum loads (usually in pounds or kilograms).
"H" indicates the speed rating: this tire has a top speed of 130 miles per hour. In the old European bead marking system, it is represented by 215/65HR15. Different English letters represent different speed levels.
"DOT" means that the tire meets the safety standards set by the U.S. Department of Transportation (DOT). The 11-digit numbers and letters immediately after "DOT" represent the tire's identification number or serial number.
