LDRC Tires - They're not all the same

Hi guys,
When it comes to LDRC tires, watch that tread pattern, nobby outsides mean a slightly larger tire that doesn't work with the NSX. Watch the color of the wheel for clues to the compound, plain Jane white or black is probably soft rubber and fancy wheels are hard drift tires. Read the add for clues as to the compound.
Do you drive to wrench or do you wrench to dirve?
