In the general comments you list "handles very well" as the number one comment right after you went on about crashing into a guard rail. Most performance tires and even many mid range all season tires are good for maybe 30K miles, depending on how you drive on them and how often you rotate them. If you needed them at 10K miles, then I could see complaining about that, but 27K miles isn't an extraordinarily low amount of miles, on any given set of stock tires, to need replacing at.
Unfortunately the stock tires of most cars are pretty cheap, and add to this the "fun to drive” quotient, and the receipt ends up with worn tires. I had a 1993 Isuzu Impulse that I swore ate tires while parked. Turns out a 21 year old "professional driver" and sport compacts are a tires dealer's dream come true.
I agree the tires are not good. I have about 50,000kms or 30,000 miles on my Mazda 3, and one tire is bald, and the other 3 are very near to be replaced. And yes, I rotate my tires as recommended by the owner's manual.
Don't knock Mazda for tires made by another manufacturer. If you knew the tires were worn, you shouldn't have driven on worn tires. Driving on tires with too little tread depth is illegal in most areas. Also, it is the lessee's responsibility to maintain the car (e.g. replace the tires), not Mazda's. It sounds like you're just not happy with the lease process?
The owner admits the tires were almost completely bald. I believe he didn't check them at any point, because any single tire on the market, when the tread is worn out or very thin, loses any adherence when doing emergency braking in the wet.
Do not at any moment keep driving with worn out tires! They will do fine in the dry. And then one rainy day, when you will have to smash the brakes because of the car in front of you, they will perform like they're on ice.
I just came across this review, and I also own a 2007 Mazda 3S. I am happy with the car, but I also needed to buy 4 new tires before my car hit 40000 miles.
