Driving on bald rubber when the first slush hits is a great way to meet a snowbank. Keeping your car safe in winter means paying for proper traction, which usually runs you about $1100 for a full set of winter tires and steel wheels. Prices on winter rubber dip in late September before the rush, making it the smartest time to shop mail-in rebate sales and lock down your setup.
You want to negotiate your tire and wheel package price at the shop before you talk about how you are paying for it. Get them to bundle mounting, balancing, and valve stems into one flat total. Once you have the final number, use your financing window just to handle the balance without letting interest eat into your budget.
Remember that the intro window is a strict deadline, not free money. If you still have a balance left on the Citi Simplicity® Credit Card when those 18 months are up, you will get hit with interest on the remaining amount.
