Can I put 20 inches wheels and tires on my 2006 Infiniti G35 coupe?

What is your question?

My wheels are all bent, so I decided to buy new wheels and tires. But the place that I bought it from put 20 inches wheels and tires on it. And my old wheels were 19 inches and I just want to make sure that nothing will happen to my car for putting it on.

What makes this problem better or worse?

On hwy feels like my tires are gonna come off of car

How long has your 2006 INFINITI G35 had this problem?

Probably a month
