Modern cars are using less and less fuel, and there is a growing proportion of electric cars on the road. This results in lower fuel excise incomes that the government is collecting. Therefore, according to Gocar.be it is considered to implement a tax on tires.
In a way this reasoning makes sense – if you drive more, or use a heavier vehicle, you will be taxed more.
The other side of the coin, of course is the safety. This seems like a recipe for disaster, because it encourages to use tires longer, maybe even after tire tread depth is below the legal limit. Not buying winter tires will also be considered.
Tires can be a relatively large purchase, therefore a reasonable tire buyer will very likely decide to take a trip and buy them abroad.
