bahaya tu.. time jalan kering takpe la.. kalo time basah.. kes tu yg boleh jadi terbabas tu.. ( kalo high speed la ).. kalo bawak pelan takpe..
jaga2 la bawak keta tu dlm highway.. engineer reka ada rotation tu ada sebab.. bukan main suka suki aje nak blasah belah mana.. better pegi ubah balik kedudukan ikut arrow tu..
bg aku..
tayar = nyawa.. jaga elok2 la.. |

Asymmetric tyres
An asymmetric tyre has different tread patterns on its inner and outer sides, giving it a distinct performance advantage over a tyre with a symmetrical or directional tread.
The tread pattern on the inner side of a typical asymmetric tyre has more grooves giving better grip on wet roads
The outer side has a higher plain surface area, the benefit of which becomes apparent when cornering at speed on a dry road
Unlike a directional tyre, an asymmetric tyre can be used in any position on the vehicle. It is very important however, to follow such wording as 'inside' and 'outside' on the tyre's sidewalls to ensure that the tyre is fitted 'the right way round'. As with directional tyres, incorrect fitment can seriously impair performance. And, again if you do use a wheel with an incorrectly fitted asymmetric tyre, it should be regarded strictly as a 'Temporary spare'. Please note:
A 'Temporary spare' is limited to 50 mph (80 kph)
A car whose tyres are not fitted in accordance with the instructions on the sidewall will fail its MOT
Some tyres are both asymmetrical and directional. These tyres carry markings on the sidewall which a) indicate the correct direction of rotation and b) identify the inner- and outward-facing sides. Failure to observe these instructions will impair tyre performance. The above recommendations will also apply.

Directional Tyres
Designing a tyre tread which will operate equally well rotating in either direction inevitably involves compromises which limit ultimate performance in some respects.
Directional tyres, on the other hand, are designed to rotate in one direction only (indicated by a conspicuous arrow pointing in the direction of rotation on the sidewall along with the word "rotation"); so performance - wet grip, directional stability and handling - far from being compromised, is optimised.
Obviously, a directional tyre can deliver this improved performance only if it is correctly fitted to ensure that it rotates in the direction indicated on the sidewall.
What happens if you are unfortunate enough to have a puncture and your spare wheel is fitted with a directional tyre designed to rotate in the opposite direction to the tyre which it replaces? You are recommended to treat the spare wheel as a 'Temporary spare', drive at reduced speed and have the tyre correctly refitted as soon as possible.

Asymmetric tyres (yg ni kena pastikan outside dan inside nya betul)
Directional tyre (yg ni kena pastikan arrow nya betul)

lagi maklumat berguna pasal tayar
typical lifespan tyre is about 4 years. Once it reached their lifespan, rubber would have started to harden & more prone to crack when running under hot weather. So to be on the safe side, do consider changing your tyre once it抯 expired irregardless if the threads are still good.
So how to check tyre expiry date? The date of manufacture is usually indicated on one side of tyre in week-year format. For example, the following shows 3103 which means the tyre was manufactured on week 31 of 2003 (There are 52 weeks in a year). So just add 4 years to workout the expiry date of your tyre.

satu lagi aku musykil, kalau kita dah upgrade tayar dari 13 ke 14 atau 15 inci , kita perlu masukkan tekanan angin tayar ikut standard kat tiang pintu tu ke atau ikut suka hati jer? |
