Take care when it comes to tyre safety
WITH what appears to be an ever increasing rate of fatal accidents where vehicles are either transporting people or goods we should turn our attention to tyres and the condition thereof.
Tyre pressure is extremely important. It is the air in a tyre which carries the load, so if the inflation pressure is not correct it could lead to excessive flexing and overheating, and eventually failure.
A correctly inflated tyre can be rendered as under-inflated if the load is excessive – more flexing, more heat and a failure is inevitable.
Somehow a message or form of education needs to be done to inform motorists of correct tyre pressures for their size of tyre and what it is being used for.
In short, the tyre and pressure must suit the purpose for which it will be used.
The tyre tread is also extremely important. Have tyres checked at a reputable tyre dealer, that can in most cases guide you through selecting the correct tyre pressure v load for the weight of the vehicle.
Do not fit regrooved tyres or tyres which the vehicle manufacturer has not specified. Once again, go to a reputable tyre dealer and take their advice.
Check tyre pressures regularly to detect slow leaks from valve, valve core or slow punctures from foreign objects in tyres.
Use metal valve caps with washers to act as a secondary seal on the valve. If the valve core leaks, then the valve cap will prevent air from leaking out.
If you do not have a TPMS (tyre pressure management system) in your vehicle, it is difficult to note a slow puncture or air leak.
When air leaks out of the tyre, it causes it to flex more and generate heat, which eventually could cause a premature failure. Heat can also affect the performance and mileage you get from your tyres.
When fitting a new tyre or having a puncture repaired, buy a new valve. Valves can crack and deteriorate over time from the heat build-up in the rim from braking. If a valve leaks the same cycle of heat build-up or rapid air loss can occur.
