I need new tires on my wagon. Since i can't buy white wall tires in Europe anymore, i have to order them from the USA. That means shipping will cost a lot. My question would be, which one to choose. Since shipping cost so much and i want a good tire, the pricetag is no issue, as long as they they have to come with the white stripe. The ones i have now are 225/75-15, but i read somewhere, that wagons came with 235's??
