Volvo C70 Type N ??

Hello Together, two questions… what did the new Volvo C70 (from year 2006) mean for a designation to distinguish it from its predecessor. In the INternet and EBAY you often find the name in the report for the type “N”… is this the “old” C70. I’m looking for rims for the winter tyres. knows but only 5 holes hole circle 108mm The rest should not be so wild, or ? Tyre size 215 and important the load index of at least 90 because of the vehicle weight… What can you tell me about it? I wanted to take the 16 inch variant rather because cheaper. But if there is a set 17 in favor of EBAY or tyre dealers, I don’t say no either. So which expert can help me if I have to pay attention to press depth and co….? and which model our new C70 actually represents. Many greetings FRANK
