I am thinking to do this... I didn't get DCC and therefore took 18" rims. Now I don't know what to do I am thinking of two options:
#1 go with 18" winter tyres and when my summer tyres are worn out, I'd probably go for new 19" rims for summertime (and hope my spine accepts bumpy Slovenian roads with 19" and no DCC )
#2 go with 17" winter tyres (205/55R17) and use 18" for summertime
I believe I haven't seen any Octavia RS with 17" wheels. I am afraid it might look a bit awkward have anyone seen it or installed 17" to his Octavia RS?
BTW, as I can see that you were talking about Dezent above, do you know it? Are Dezent rims good for winter (if there is some difference at all)?
