According to NDA, this practice is one of the main causes of motor accidents and it poses a significant risk to drivers and passengers alike.

NDA emphasised that high-quality tyres are essential for safe driving.The treads on tyres keep the rubber in contact with the road surface, providing good traction and preventing slippage.

This is particularly important on the often-uneven roads of Sri Lanka, where deep grooves are necessary to keep vehicles away from skidding.

Unfortunately, some businessmen are encouraging motorists and riders to re-groove their worn-out tyres, putting many lives at risk.

While experienced drivers tend to avoid these re-grooved tyres, many new drivers of motorcycles or three-wheelers are using them.
