Common false logic, car is low value so should have low value tires then complain about worse performance.
A beater has no difference in tire benefits than a new vehicle, maybe even more important to get better tires to make up for the other deficits. If you drive it slower and accept the trade offs, okay then, don't complain about low end tires.
... just suggesting that your results don't magically change if the vehicle is older. For good results you still, every bit need the same quality tire as a brand new vehicle would have, of an appropriate size of course.
One exception is if you are planning on selling it soon, then of course you don't want a large investment you won't benefit from.
You may not always get what you pay for, but you always pay for what you get, except black market nonsense.
Long story short: Your tire choice should be based on the driving environment and # of miles per year, not the value of the vehicle. I've gone off on a tangent, you can just ignore this post and drive on.
