I know that you do not advise using winter tyres on only some of the wheels. However, would this also apply when it is not winter - we have 2 cars (a Kia Venga 1.4 petrol manual and a Volkswagen Transporter Shuttle 1.9 manual) both of which may need 1 or 2 tyres changing in the near future. I would like to replace them with all weather tyres (Goodyear Vector 4Seasons or similar) and then replace the remaining tyres with the same once we get to November (so that I can stagger the cost).
