Your reason for wanting to go to a 16 may not the best solution you are trying to achieve and may cause other yet unforeseen problems.
I would NOT recomend changing to a 16 based on your first response that while the wheel size itself will fit it may change the steering, handling and braking characteristic which may not be in a positive manor.
I am sure that you will find many that are
experienced in the tire wheel wheel business that will also concur.
I
strongly recommend to contact a local Tire and wheel center or on line Tire Rack and discus with them the best option for your question.

I often post this and threads like this is a good reason why.

Automotive Forums
Another source of information many people use on the internet are automotive forums. There are hundreds of forums dedicated to specific vehicle makes and models as well as more general automotive forums. Forums contain a wealth of information, but also a lot of misinformation and conflicting information.
The typical forum user will post a question in hopes that other forum users will respond and offer an answer or advice on how to solve the problem. But with all forums, there is no guarantee that anyone will respond or that any responses they do receive will be accurate or helpful. It all depends on the other forum members and who posts a response. Many forum users are quite knowledgeable and can provide exactly the kind of answer you are looking for. Other forum users want to be helpful and may venture a guess or offer an opinion that may or may not be accurate or may be totally wrong. In other words, it may be hard to distinguish good advice from bad advice.
Most forums are moderated to delete spam, rants and off-topic posts and comments that don't belong on the forum. But in most instances, the accuracy of the posts and responses is left up to the forum users. There's no editing or vetting or review of the comments that are posted. Consequently, if inaccurate or incorrect responses are posted to a question, other more knowledgeable users may or may not challenge a post or offer additional information.
We've seen many forum responses degenerate into endless bickering between conflicting points of view. We've also seen a lot of posts that totally contradict one another. There's nothing wrong with a good debate provided the people involved know what they are talking about. But unless there is some resolution to the debate, or some serious fact checking involved, the person who posted the original question may be left confused and no closer to finding an answer than when they started.
