Name THREE purposes of the raised lugs on tyres and b what can happen to a dumper if the lugs are severely worn?

The raised lugs on tyres provide improved traction, enhance grip on uneven surfaces, and assist in self-cleaning by expelling mud and debris. If the lugs on a dumper's tyres are severely worn, it can result in reduced traction and stability, leading to increased risk of slipping or tipping over. Additionally, worn lugs can negatively impact the dumper's handling and overall performance, making it less effective in its operations.
