74.0 Tayar - berpijak di bumi nyata!

Boleh dikatakan majoriti kita memiliki sebuah kereta atau sekurang-kurangnya sebuah motosikal. Walau jenis apapun kenderaan kita, yang menghubungkan ia dengan bumi ialah tayar. Jadi, berilah perhatian kepada tayar. Ada di antara kita yang tidak pernah pun menoleh ke tayar kereta atau mengambil tahu tentangnya. Kita mungkin berkata, "apa perlu aku ambil tahu tentang catatan pada tayar kereta, kalau botak dan bunganya dah haus, tukar saja yang baru." Ambil tahu tentang tayar akan menguntungkan kita ketika menukar tayar baru.

You will find the size of a tyre on its sidewall. With a quick explanation as to what the different numbers mean, you will see that it is very quick and very easy to find out a tyre's size.
