E39 540i tires

[E39guyE46]

Has anyone tried the cheap amazon atlas tires looking to put 2753518 on the rear and leave the front ones stock since they are still brand new if that tells you something about my driving, i tried continentals but they’re kind of expensive so I’m just looking for something cheap this time because they’re gonna be gone within months I know “you get what you pay for”, I figure the sidewall will still have 2.5 mm different from front to back. What y’all think am I making a mistake by going for a bigger size and leaving the front stock (currently front, 2354018 and rear 2653518)

Gone within months, as you are selling the car? Would it be viable to get a set of used tires as a stop gap to get you a few months in, rather than some random crap tires?
