would balancing beads cause tpms sensor to come on, and shaking over 70mph?

i took my car to my mechanic for these issues, and they said my tire sensors read correctly, and that the tire beads may be causing the issue since my tires are cheaper ones. wanted your guys’ advice. current tires are kumho solus, and i’ve had them for about a year ish, was told they’d need replaced by end of summer. thank you in advance!
