If i need 2+ tyres, i have a look on the internet (tyre shopper), the last two i done on the van was mid range avon's from national tyres, but i have put cheaper on. I only do less than 2k van miles a year as my work is within 4 mile area, and i just drive slow with a the tank in anyway. Different on the car, i go for the quality michelin pilot sport 3's, for motorway higher speed driving.
