I hesitate to say it James but those will be van tyres. When you think that tyres will last you ten years at least on a low mileage and that it is the only contact you have with the road economizing on tyres makes no sense to me.In relation to the money you spend on your car buying a decent tyre is not that expensive – over the life of the Tyre, probably a tank of petrol per tyre.
So Blockley 185 R16 seem to me a good choice and will look right on the car.
