Mkuu, mie sipendi kubishana na watu wasio na uelewa wa jambo wanalobishia. Watu hawatajua tofauti yetu. Maneno yako yanajidhihirisha kwamba wewe ni mbishi usiyejua mambo, unaleta ujinga wako tu humu JF. Unajidharirisha tu humu ndani ya JF. Kama huelewi jambo omba kuelimishwa badala ya kujifanya mjuaji.
Kwa faida yako, hebu angalia hapa chini ujue concept ya tyre speed rating; natumaini unaelewa lugha ya kiingereza Zaidi ya ulivyojionyesha kwenye comment yako.
Tyre Speed Rating
The speed rating of a tyre is displayed on the sidewall. Like in the image, you will find it at the end of the tyre's size. It is always represented by a letter - in the following example the tyre speed rating is "W".
Once you know your tyre speed rating, you can work out what is the
maximum speed your tyre is capable of maintaining.
For example, the "W" rating seen in the image, tells us that this tyre can reach speeds of up to 168mph.
Speed ratings are based on tests in which engineers run the tyre at 6.2 mph steps, in 10 minute increments, until the required speed has been met.
Effect on Car Insurance
It
is very important that you check your speed rating before buying tyres. Choosing a tyre with a lower rating than is appropriate for your car can
invalidate your insurance.
