Right now, there is a set of worn-out tires on it, and I plan to replace them with the Bridgestone RE-11's if I keep the car and/or the wheels. The tire size 215/40/16, but I plan on going with a 225/50/16 if/when I replace the tires.
BTW, the Falken Azeni has fantastic grip, but it is known as a pretty harsh-riding tire even amongst the people that like them. Lots of sidewall stiffness at the expense of comfort.
You would probably see a big comfort difference switching to something like the Toyo T-1, or presumably, the Bridgestone RE-11 as well, even with your current wheel size and weight. Going with a 50 profile instead of the 45 might help a little too. My guess is that changing the tires would make a bigger difference than losing a few pounds of wheel weight, though doing both would be great.
Let us know what you do!
