For car tyres, you may get only 10000 k's, or even less, if you are harsh. But if you treat them right, a good tyre could last 80000 to 100000 k's. All tyres have a tread wear indicator. Once you tyre is close to this indicator you should be looking at replacing them.

Atomic absorption (AA) is a scientific testing method used for detecting metals in solution. The sample is fragmented into very small drops (atomized). It is then fed into a flame.Isolated metal atoms interact with radiation that has been pre-set to certain wavelengths. This interaction is measured and interpreted.Atomic absorption exploits different radiation wavelengths absorbed by different atoms.The instrument is most reliable when a simple line relates absorption-concentration. Atomizer/flame and monochromator instruments are key to making the AA device work.his interaction is measured and interpreted.
