Question about GS replacement of 20-inch wheels and tires
My GS is currently using 19-inch wheels and tires. Now I want to change to 20-inch wheels and tires. How should I choose the data of the 20-inch wheels to suit my GS? There are also tires. Is it more appropriate to use 235 35 R20 and 265 30 R20? But I am worried that the aspect ratio of the rear wheel 30 is too thin, and the tire is easy to break. Is there a more suitable tire matching method?

Wheel fitment is a complicated question.
Are you lowered and how much? Do you want to have very aggressive fitment? Do you intend to or are you willing to stretch tires? Do you intend to run aggressive camber? Are you willing to modify the body at all to make the wheels fit? Are you willing to live with slight rub on the inner fender liners? Do you want to run wider tires for more traction?
Do you want a simple bolt-on solution with no additional work?
Your wheel specs will be dictated by your answers to all of these questions.
For the wheel itself, it all comes down to the width and offset. Members have installed a wide variety of 20" wheels with different widths and offsets; some have to run narrower or shorter tires to avoid rubbing, some bolt right on but have much less aggressive offsets, some are on air ride with camber arms.
Tire size is dictated by your handling goals, your offset, your tolerance for rough roads, and the quality of your roads themselves.
Unfortunately, we cannot provide you with good answers until we know what your goals and compromises are.
This is a good starting point. This website has wheel specs, tire specs, and suspension modifications for each pictured car. Look around and figure out what you are looking for, and we can probably help you achieve your desired stance.
