Just to let you know, depending on the size of the aftermarket wheels, they can cause stress on the tranny that can cause premature failure. being that it's an Altima, I'm going to assume he is running 19" or bigger, If so, I would say yes. Another problem with bigger wheels is that they tend to weigh more. However, it wouldn't fail that fast. Also, your boyfriend's biggest mistake is not doing his homework before he bought a 2015 Altima. He would've known that they have been plagued with transmission and engine issues since 2002. Even a 2019 Altima owner is driving on borrowed time.
