Need to know answer by today...

I put new rims on my 07 Yaris LB and am going into the dealer tomorrow for a cat. converter swap (sulfur smell). I wonder if the are obligated to do a wheel alignment if I ask them to after I put the new wheels on. The wheels were done about one month after I bought the car. They are DiscountTire wheels. If I tell them "It's steering kind of weird" should they do the alignment under warranty? Thanks..

p.s. I thought somewhere that you get one free alignment during the first 12,000 miles??
