When you replace your tyres, you should avoid fitting different types to opposite wheels of the vehicle on the same axis, as this can alter the tyre pressure on each wheel, and offset the cars weight distribution and handling. It is recommended that you replace all four tyres at the same time, or in front pairs or back pairs.
If you shop around, you can pay as little £100 for a set of budget tyres, and around £250-£300 for a good quality well known tyre brand.
Though it is worth taking into consideration that the more you choose to pay for a tyre the better quality it generally is, and the longer the tyre will last. Shop around and consider lesser-known brands but avoid part-worns for safety's sake.
