Buying cars for your car or van can be expensive, especially if you have to replace all four at the same time. With tyres, it is not always economical to buy the cheapest tyres as they often will not last very long and you may find that you have to end up replacing them after only a few months.
One option you have is to buy part worn tyres. Part worn tyres are often tyres that have been shipped in from other parts of Europe or have been removed from cars due to be scrapped in the UK. Rules in other parts of the EU state that tyres have to be changed at 3mm as opposed to 1.6 in the UK. These tyres are then sold on as part worns. The issue with part worns is that you may only get 2 or 3 mm of tread on them and although they are often a lot cheaper than new, you will not have much driving on them before they need replacing. In fact some garages recommend changing your tyres at 2 or 3 mm anyway.
