Hello, I would need a decision help because I don’t know very well about tyres and rims. I got winter tyres to my Prius extra for 200€. I still didn’t have them missing the screws. After I got the sent the workshop said they can’t pull them up because the tires have strong saw tooth formation or caskash damage with bump formation. They didn’t want to put on it. I didn’t want to do this either. But since I paid 200€ for the winter tyres I wanted to get the money back. Then I would have to buy new ones, which they would probably do. The aluminiums are actually nice. Dark for the dirty winter. And new ones cost 500€. I have now written down all the numbers of the tyres I have. In the vehicle license it says: 215/45R17 87W 215/45R17 87W – Summer rims: I couldn’t find a designation on the rims. Can’t pick up the Prius. Sommerr eifen: 215/45R17 91W (So almost exactly what is in the vehicle’s license.) Winter rims: 6.5Jx16H2 Z6516 SD Winter tires: 195/55 R 16 87H M&S Now is the question… if there are R16 tyres on the winter rims, are they even allowed there only R17 mentioned? Besides… I can forget about the tyres. So must buy new ones. Can I make 215 on the winter rims or would that look funny because the rims are further inside? I have no idea if the rims are as thick as the rims are. By the way, I have a bill from the previous owner that says the summer tyres have fuel efficiency E. That’s 0.4l more consumption than if it were A. Or 0.3l on 100km if it was fuel efficiency B… I don’t think that’s worth looking at 5€… or are the fuel efficiency data not trustworthy? But first I need winter tyres. And the question is whether I should return the old rims and broken tires and 2 00€ or keep the rims and should put new 215 winter tires on it. It should ideally look like with the summer tires, only darker rims. But that is not possible with the R16 rims or? The rims have a smaller diameter than R16 and that should also mean wrong speedometer indicators or?
