I was of the "brand X tires are worth it because they are better" mindset for nearly 30 years and never bought anything but "top of the line" tires. The last time I needed tires I was in a bind financially and bought the absolute cheapest tires I could find. It was a REAL eye opener...I have ZERO complaints about them and only paid about 1/3 of the price I paid for the set that they replaced.
I think maybe several decades ago there was a significant difference between the quality of low end and high end tires. With today's manufacturing technology though, I feel the difference is a lot more about paying for marketing and CEO's salaries than actually getting a better tire. Just my NEW opinion.
Note that the above post does not apply to ST tires of dubious brand names.
EDIT...I intentionally left out brand names but just realized you (the OP) were comparing to Falken tires...those just happen to be the cheap brand I referred to above (although a different model).
