Slightly wider ... On my nine-seat Mk6 2.0 tdci Tourneo I changed the 195 / 65R16 tires to 215 / 60R16. Alloys 6.5Jx16 "wheels. Fuel consumption increased by about 8-10%, top speed decreased by about 10 km / h (6.25miles / h).
The steering force required for maneuvering has significantly increased. The sensitivity of the steering system to braking in ruts on the road has significantly increased. Ride comfort has decreased, lower profile tires are harder. In good road conditions and in sharp turns, it was more stable - much less side drift.
Van looked ... cooler. Each tire has a limited range of rim widths that can be mounted on it. That's why colleagues ask you what size of tires and rims you have. Each rim has a limited range of tire width that can be mounted on it. That's why colleagues ask what size tires and rims you have. Additionally, this permissible width is also dependent on the tire profile. I enclose a link to the table where the dimensions of the tires and the dimensions of the rims on which these tires can be fitted are given.

It is assumed that if the change does not exceed 2%, there is no need to interfere with the settings of the mileage counter and the speedometer. Use popular tire calculators available on the web for this check.
You should also remember about the appropriate tire load index.
Overall: There are pros and cons to switching to wider tires.
