The link is for tyre sizes and not rim sizes, which addresses only half the issue. The current and new tyre sizes you've mentioned is OK as the change is only a 1% difference. There might be trees sizes that gives a much lesser difference (195/60R15 for example), but trying to find tyres of that size might be difficult. 

The other half of the problem is the actual rim you're going to replace the stock ones with. You need to make sure that the stud pattern matches with the car, and importantly, the width and offset of the rim doesn't cause the tyres to rub inside the wheel well. Stick to rims that have an offset and width that are as close to original as possible. 

A simple Google search for "wheel offset" will give you more information. There's information on the forum as well. Do a search. 

Good luck!
