If you do not have the Mercedes-Benz Roadside Assistance program, which lets you call a Mercedes representative and have someone come to your location and change your flat tire, you will need to know how to change the flat yourself. Changing a flat tire on a Mercedes is the same as changing a flat tire on any car.

Step 1

Drive your car to the side of the road in a safest spot as possible where you will avoid oncoming traffic. Park your car in a flat place, so you can easily jack up the car. Put on the parking brake and your hazard lights.

Step 2

Locate your Mercedes-Benz spare tire, lug wrench, and car jack located in the trunk of your car. Lift up the trunk liner to find the tire and tools. The Mercedes jack is like any other jack. It just needs to be opened to the primary position in order to work.

Step 3

Loosen the lug nuts on the flat tire with the lug wrench. The five lug nuts are located around the Mercedes star logo in the center of the rim. Do not remove the lug, only loosen them about one turn.

Step 4

Place the jack under the car and raise the Mercedes until the tire is about 1 1/2 inches off the ground. If you look under the car you will see a flat area where your jack will fit. If you are changing a front tire, the jack point will be behind the inner part of the tire. If you are changing a back tire, the jack point will be in front of the inner part of the tire. Refer to your Mercedes-Benz owner's manual for an exact picture of the jacking points.

Step 5

Use the lug wrench to completely remove all five lug nuts, then pull the tire straight out to remove it. You may need to kick the tire to loosen it before pulling it off.

Step 6

Clean the wheel contact surfaces. There may be dust and particles on the areas where the spare tire fits onto the car.

Step 7

Put the spare tire on the car. Push it on straight with the lug nuts holes aligned until it cannot go any further.

Step 8

Put the lug nuts on the spare tire and screw them in loosely just so they are attached and the spare tire stays on the car.

Step 9

Lower the Mercedes to the ground by cranking the jack counter-clockwise and remove the jack from underneath the car.

Step 10

Tighten the lug nuts in a star pattern. Tighten the top lug to 50 percent tightness then tighten the opposite lug nut to 50 percent and continue to tighten all lug nuts like you are drawing a star. Repeat again and tighten the lugs completely. It is important to tighten the lugs in a star pattern so that the tire is secured straight.
