I have a 2006 300C with the 18" standard rims/covers. I have read that there are chrome covers on the lug nuts. My question is - Will the standard lug wrench supplied with the car remove these lug nuts? Do you need to remove the covers first? There were comments about the sizes, wrench requirements, damage to the covers, etc. and I just want to make sure if I have a flat on the road that the std. wrench will work. Thanks, regards, Bob.
