My 2008 Civic Si (A/S tires) 4dr's steering feels much lighter turning left than it does turning right. Does anyone else notice this?

Dealer claimed it is normal after driving my car and the manager's 07 Si 4dr with summer tires. I drove the managers car and it felt way tighter than mine, though it had 17k and the grippyer summer tires.

 

Check the air pressure in all 4 tires. If OK, also you should try switching the two front tires/wheels left to right. If that makes the problem switch sides it is likely a bad tire. Do that only as a temporary check. Some tires don't like to turn backwards.
