Update

Neither myself or the roadside assistant man knew how to change the spare on a Mercedes. The spare in the trunk was deflated which we stared at dumbly for a bit. Then we pulled out the manual. The car says of has a toolkit but it took us several minutes of searching to find it.

The toolkit made me laugh as it came with everything. Compressor to inflate the tire, special lugnuts for the spare, flashlight, and little white gloves so you don't get your hands dirty.

Since we were now a team and not him paid to help me, he gave me the task of figuring out how to get the compressor working while he removed the old tire. I should of put on the little white gloves...

We got the tire on and since it has a max speed of 50mph I turned back towards Owosso to get a new tire put on. He said it was under warranty but I didn't have enough tread. Also my rim is a little bent so I might have some vibration. Great.
