It is perfectly O.K. to run your current tires if they are the correct size for your new wheels and less than seven (7) years old. It is important to make sure that you return the tires to their original position on your car once mounted on the new wheels. In other words, if you take a tire off the left front wheel, you should return the same tire to this location. Also, we recommend checking your alignment once the new wheels are installed and realigning your car if necessary.
