Ramon,
Don't feel bad. We all had to start somewhere. Try tirerack.com They will show your car and how new rims and tires will look on your convertible. Remember that you have a base car with only 150HP (and the convertible is heavier already) so if you put wider, larger rims and tires on you will hurt the straight line performance of PT quite a lot. i.e. more tire to move means it takes more power to move them. If that is not a concern then go with whatever you think looks the best for the $$$$. But DO read all the tech info on tires and rims before you choose. It will help you understand how they affect your car overall. BTW, I have a GT convertible with the 17" chromed star rims and larger factory tires. I will be changing them out soon and will have that set up for sale pretty cheap if you like those rims.
