Yes. The narrower the tyre, the narrower the contact patch but have to beware of wet. Initial batches of hybrid always go for 165 or 175. The Insight and City and Jazz uses 185 but in US they initially use 175 with Eco tyres. Some on 16" 6.0JJ width even downgrade to 15" 5.5 JJ width then pakai 175/65.

This is the first principle of fuel economy but cannot be overly extreme and pakai too narrow. Each car model has a minimum for safety and handling perspective.

Bought my j5 2 months back. Mileage around 2000km. Is this type of wear normal? Seems like bad composition design to me.
