So this might sound dumb, but had a flat tire, called roadside assistaence. they couldn't change my tire because my bolts need a "nut lock".
1. so this is the second time I had to change a wheel after a flat. first time the guy who showed up had a four way wheel lug, used 17 side to change the wheel. "NO NUT LOCK WAS USED"
2. About 2 weeks back I had my tires rotated at a tire shop. They didn't ask for a nut lock(Maybe they had their own, I don't know)
My question, I bought this 2013 S550 4matic Sports package last year December from a MB dealer, do I need a nut lock for this(see Pics)? My guess is no, refer to point 1. I had to get my car towed to the tire shop that did tire rotation, point 2. Unfortunately they don't open on Sundays so I just left it there will call them tomorrow monday 8/12/2019. I just don't want to be stranded next time in case it happens in the middle of nowhere.

No need for a nut lock, those are the stock lug bolts for your car (and mine!)

You need what some call a flower head socket, although I've heard of people using a standard 17mm hex socket and also people replacing lug bolts because the chrome covers are soft and easily damaged by the hex socket.

Here's a cheap one on Amazon;

And here's what I bought a Hazet 905 SLg-17, I can't help it I like good tools! I bought two and stuck one in the trunk with the toolkit, for the precise reason you encountered. The folks at Discount Tire where I buy my tires always have the right socket, even verified they have the odd flower head socket.

In a pinch, these can be removed with a 17 mm socket - but the SS bolt head will likely be damaged.

The car's OEM tire iron has the requisite flower head.
