Why? Do you have wheel size envy? Don't do it. 19" tires cost w a y more. Ride and handeling will/may suffer. Stick with "18's.

Std 18" sizes and offsets:

F 7.5 x 18 50et
R 9 x 18 52et

Here's a calculator that will help you see how your prospective rims will do:

1010TIRES.COM - Wheel Offset Calculator

You don't want to move the fronts too far in as they'll rub the strut. You might have emergency brake clearance issues if you move the rears too far in.

Just about every possible question concerning wheel and tire fitment has already been asked and answered in this forum. Doing a search (see toolbar above) will give you access to far more information than will get posted in this thread.

The front is actually a very good fitment. However, the rear offset is too high. I would recommend a 15mm spacer for the rears. BTW, what part of Mass. are you in ?

19" wheels will look funny unless you lower the car .

Forget online offset calculators, they don't deal with real world considerations. As I said, lowering the rear offset to a range of +40 to +45 is ideal. Especially in view of the fact that the front fitment is currently at +43.

Man, so much more response in General Discussion than Technical

http://986forum.com/forums/performance-technical-chat/50006-tires-rims-question.html

I thought someone deleted my posts when I got in this thread.
