Drivers are being warned about a major petrol station change that will see them fork out 50p every time they inflate their tyres. The service used to cost 30p for three minutes but will now increase to 50p for five minutes. Sainsbury’s has recently infuriated motorists after it announced that the cost of inflating tyres will increase by 20p. The supermarket giant follows in the footsteps of Asda, Tesco and Morrisons which are already charging 50p for the service. A spokesperson from Sainsbury’s stated: “Back in July, we started offering customers five minutes rather than the previous offer of three minutes, with each minute remaining at 10p per minute.”This is in line with the wider market offering and based on customer feedback.”READ MORE: Electric car owners warned about towing trailers and caravans Major petrol station change will see drivers fork out 50p for necessary service.
