XC 90 2007 Winer tyres do not fit my volvo-retaining bolts

[loveVolvo]

Hello: I recently bought winter tires from tireRack.com, but they do not fit my XC 90 2007 SUV. The retaining bolts on my volvo prevent my new winter tire to fit. I called tireRack, and they suggest removing the retaining bolts. However, the dealer was hesitant to do so. I am confused. Should I return these tires to tireRack, or should I remove the retaining bolts on my Volvo and make it fit?

Thanks a lot!
