DO rotate your tyres on a regular basis. It's a good idea to consult with an expert about the best way to rotate the tyres for your car.
DO take your car in for a service if the tyres are showing uneven wear and tear, chances are this is related to your vehicle's steering or wheel alignment.
DO remember that space saver tyres often found in the boot of your car are temporary fixes and should not be long-term replacements for your tyres.
DO replace your tyres before they go bald and if you notice that they are wearing out at the edges then get a wheel alignment done quickly.
DON'T speed as it wears out the tyre. Your tyres will last twice as long if you travel at around 80km/h as opposed to travelling at 100 km/h.
DON'T buy at the cheap end of the tyre market; you end up compromising your own safety.
