Yes, those are factory rubber. They are ok on dry, not bad on wet, not so great in snow. Check the tread depth and you might consider going out and getting quality rubber on the vehicle. I recommend Goodyear comfortreads, or Michellin Harmonies. But whatever you do, do not get cheep rubber. This car really handles very well in snow with good rubber on it.

A word on inflation pressures. Your front tires should be 2psi greater than your rears, or better stated, a 2psi difference from front to rear with the front always being the higher pressure. So, if you run 40 psi in the front, you should run 38 psi in the rear. The factory placards that should be on the driver’s door post indicate factory tire pressure. You can use that, however most folks here think it is a little low, however it is the recommended pressure and your ride will be pretty darn good at that pressure with factory rubber. On the other hand, new quality rubber at higher pressures seems to deliver very good ride for most folks.

If your tires do not pass the penny test, they should be replaced. If your tires were run at low inflation for a long time, that would increase the wear on them and would explain the short lifespan you suspect.

Please post more questions if this is unclear or you want more clarification on other stuff.
