LOCAL: Maksud tulisan yang berada di atas tayar anda, ia bukan perhiasan semata!

Stance in the rain
Tayar adalah getah hitam dan lembut yang berbunga berbentuk bulat sempurna yang berfungsi untuk mengerakkan kereta di atas permukaan jalan raya samada yang bertar, tarmac, dan juga berbatu. 

Tayar tidak dapat berfungsi secara sendirinya dan penggunaannya harus bersama-sama dengan rim yang menjadi penyokong dan penyampai kuasa gerakkan dari enjin kereta ke tayar dan ke atas permukaan jalan raya yang akhirnya akan menjadikan kereta anda bergerak laju diatas permukaan jalan raya tersebut. Rim pula didatangkan dengan pelbagai saiz, bentuk rim, berat rim, dan juga jenis bahan buatan rim tersebut. 

Tayar dicipta dengan pelbagai saiz, bentuk, bahan binaan dan juga kegunaannya mengikut kehendak kereta serta kuasa yang dijanakan oleh kereta tersebut. Hari ini kita tidak akan membicarakan jenis tayar dan kegunaannya tetapi hari ini kita akan belajar bagaimana untuk memahami sesuatu tayar itu.

Penjelasan untuk apa yang ada kat tayar korang tu.
Glossary of Terms

Tyre Type is defines the proper use of the tyre. “P” means this is a Passenger car tyre. If the tyre had an “LT” then the tyre would be for a Light Truck.

Tyre Width is the width of the tyre measured in millimetres from sidewall to sidewall. This tyre is 215 millimetres.

Aspect Ratio 
it's the ratio of the height of the tyre's cross-section to its width. 65 means that the height is equal to 65% of the tyre's width.

Construction tells you how the tyre was put together. The "R" stands for radial, which means that the body ply cords, which are layers of fabric that make up the body of the tyre, run radially across the tyre from bead to bead. "B" indicates the tyre is of bias construction, meaning that the body ply cords run diagonally across the tyre from bead to bead, with the ply layers alternating in direction to reinforce one another.

Wheel Diameter is the width of the wheel from one end to the other. The diameter of this wheel is 15 inches.

Load Index is a number that corresponds to the maximum load in kilograms that a tyre can support when properly inflated. You will also find the maximum load in pounds and in kilograms moulded elsewhere on the tyre sidewall.

Speed Rating is a number that corresponds to the maximum service speed for a tyre. "H" means that the tyre has a maximum service speed of 210 km/h. Please note that this rating relates only to tyre speed capability, and is NOT a recommendation to exceed legally posted speed limits; always drive within the legal speed limits.

OK, yang ini mungkin asing bagi korang tapi untuk speedfreak mat rempit mat drifter mat dragger ini amat penting. Walhal untuk ibu beranak 4 yang memakai kereta MPV pun aku rasa benda ini sangat penting!

Many Goodyear tyres are available in speed-rated versions to match the speed capabilities of the world's fastest cars. Generally, it is recommended that a speed-rated tyre be replaced with a tyre having an equivalent or greater speed rating.

In situations where tyres having different top speed ratings are mixed on a vehicle, the maximum speed certification is limited to the top speed certification of the tyre with the lowest speed rating. Speed ratings do not indicate how well a tyre handles or corners. They certify the tyre's ability to withstand high speed.

*The Goodyear Tire & Rubber Company does not recommend the use of its products in excess of the legal speed limits

"DOT" means the tyre is compliant with all applicable safety standards established by the U.S. Department of Transportation (DOT). Adjacent to this is a tyre identification or serial number; a combination of numbers and letters with up to 12 digits.

"UTQG" stands for Uniform Tyre Quality Grading, a quality rating system developed by the Department of Transportation (DOT).

Tyre Grades: Uniform Tyre Quality Grading System or UTQG
Except for snow tyres, the DOT requires the manufacturers to grade passenger car tyres based on three performance factors: tread wear, traction, and temperature resistance. The UTQG rating of each Goodyear passenger car and light truck tyre is listed in the Car/Light Truck Tyre Catalogue.

Tread Wear

More Than 100 - Better
100 - Baseline
Less Than 100 - Poorer
The tread wear grade is a comparative rating based on the wear rate of the tyre when tested under controlled conditions on a specified government test track. A tyre graded 200 would wear twice as long on the government test track as one graded 100. Your actual tyre mileage depends upon the conditions of their use and may vary due to driving habits, service practices, differences in road characteristics and climate. Note: Tread wear grades are valid only for comparisons within a manufacturer's product line. They are not valid for comparisons between manufacturers.


A - Best
B - Intermediate
C - Acceptable
Traction grades represent the tyre's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. The Traction grade is based upon "straight ahead" braking tests; it does not indicate cornering ability.


A - Best
B - Intermediate
C - Acceptable
The temperature grades represent the tyre's resistance to the generation of heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperatures can cause the materials of the tyre to degenerate and thus reduce tyre life. Excessive temperatures can lead to tyre failure.

Ya, aku tak translate sebab aku ingin mengekalkan originaliti penjelasan tayar itu sendiri. Sumber berasal dari laman web

Fahami tayar anda dan rasakan tayar anda mencengkam jalan raya itu. Rasakan gigitan tayar anda ketika anda mengambil selekoh. Penggunaan bunga dan jenis tayar yang bersesuaian dengan teknik dan gaya pemanduan anda dapat meningkatkan lagi penguasaan anda keatas kawalan kereta anda.

Learn to feel the road ok guys.

P/s: GoodYear Ducaro GA enthusiast. Tayar standard gaban je kot. Haha
