Have 2002 Z-28 Camaro Convertible. Cannot keep tires inflated due to chrome alloy wheel corrosion. Trying to determine exact wheel size including offset needed for replacement wheels.

Can anyone clue me in?

Stock wheels are 16x8" with a 55mm offset. If you look at the FAQ (stickied at the top of the thread list page), you will find information on recommended combinations of wheel sizes and offset.

This is a good opportunity to move up to 17" wheels, to get the much better seelection and variation in tire sizes. The popular combo is a 17x9.5" wide wheel, with an offset in the range of 45-56mm. Typical tire size would be 275/40-17
