I've gotten several cheaper tires over the years and never really had any major issues. Sometimes you do get what you pay for but many folks don't care.
I have WestLake tires on the CX-9 currently and while the ride/balance is really good; they are a bit too noisy for my liking. The Corolla also has two cheap tires (solus maybe?) and the ride has been good, but they are wearing quickly. Can't complain too much for 115 OTD for two though. Will likely get nicer tires on the Mazda next go round.
