Fitting the wheel isn't the issue. Fitting inside your wheel well could be. R16 is your wheel size so they'll fit on the wheel. Based on this calculator:
Your tire will be 0.5 inches taller which will throw off your speedometer by 3.3% (not the end of the world, shouldn't be an issue fitment wise). But your width will be almost 9% bigger which will almost certainly rub when you turn your wheel to it's fullest. This isn't the end of the world, you just lose some turn radius. If your car is lowered it might not fit at all, but you'd have to be entering stance nation territory for it to be that much of an issue.
Also be careful with old tires. Just because they have good tread doesn't mean they're safe in even slightly damp conditions. I had some 9 year old tires on my Miata and those things were unsafe the second things got damp. I had 0 traction in that car in or after any rain.
