I bought an S4 on Dec 30. Drove home in a snow storm with the stock Contisport Contact 3 255/35ZR19. Promptly ordered a winter tire and wheel package.
Last week I went to change them over myself and found that the dealer did not mark the original tire position ie left front etc.
There was only about 200 to 300 kilometres (120 to 180 miles) on them when they were taken off.
I have checked the tires and they don't seem to be unidirectional. So is there any difference as to where each goes back on and if so is there any way to tell on the tires where they should go? With only a couple hundred clicks on them they don't need to be rotated.
Thanks.

 

It won't matter where you put them as long as they aren't directional.
