The 24P means 24mm positive offset. The offset is the amount of spacing from the center of the wheel. Here is a good page that describes it, and has a chart that converts offset to backspacing. Per the chart, you need a wheel with "0" offset.
offset to backspace

 

did you look at the tire chart in the FAQ?

 

17X8 4-108 20P
17X8 5-100 41P
17X8 5-114.3 24P
17X8 5-120.65 0P
17X8 5-120.65 41P
17X8 5-120.65 41GMP
17X8 5-120.65 0GMP
17X8 5-127 12P
17X8 5-127 6P
17X8 5-135 12P
17X8 6-114.3 37P
17X8 6-139.7HC 18P
17X8 6-139.7HC 25P
17X8 6-139.7 18GMP

None of those work

17x8 5-114.3 0p or 4.5 bs is what I think you need.

 

I'm guessing it has to do with offset. Give them a call and see if they can tell you anything. But before you do, get the wheel size/backspacing from the tire fitment chart so they can help you figure out the appropriate offset.

 

You want 17X8 5-114.3 24P. 5 = 5 bolts, 114.3 mm = 4 1/2". I don't know what the 24P represents.
