Good tyres for Euro 17" Rims

[natnat]

but 215/45 17 are ok yah?

but why would you fit narrower tyres for the CL9?

also, 215/45R17 may not be at least 91W load rating. remember, if your tyre load rating is less than the minimum requirement, insurance companies will deny your claim if anything happens and they could find any evidence pointing to the illegal tyres.
