C30 rims ATREUS against Cratus/MIDIR

Hello, at the moment I have the ATREUS 17″ rims from Volvo on it. I would like to replace them with the MIDIR 18″ or CRATUS 17″. How much are my rims (normal signs of wear after 2 years) still worth? Should I sell them best with tyres (summer tyres are completely new (1.7.2010), or rather only the rims and the tyres then pull up on the new rims? Current 17″ ATREUS rims 17″ CRATUS rims 18″ MIDIR rims • Which rim looks better on a Volvo C3 0 RDesign (Bj. 08) from ? CRATUS or MIDIR ? I personally like the CRATUS better. • Where do I offer my old rims? • What do I have to consider when I switch to the 18″ rims (of course I have to sell the tyres with the rims because they can not be combined with the 18″ rim, right?) Sorry for all my holes-the-cheese questioning, I have only been in the spell of the C30 and the associated car world for about 3/4 years. ch like to suggest other rims, but I’m more of a guard of the original rims. I mean, that’s just as if you were to remove your emblem on the radiator grille? If you’re taming for your car brand then you shouldn’t choose it at all?
