I am not a fan of low-profile tyres. I asked around and everyone is telling me that the bigger wheels generally give you a better grip, apart from the styling, but a normal driver possibly would not be able to feel the difference. If I buy a Nissan Qashqai Ti can I get the 17- inch wheels from the cheaper model instead?
You're right that most people would not feel the difference in grip, more likely in a harsher ride. Lots of dealers would be able to find a Qashqai buyer who wants to swap wheels with a Ti buyer like you.
