Excessive tyre wear
I am getting excessive tyre wear on the edges of the front tyres, I have Had the tracking done on the car twice but it keeps wearing out the edges. I have checked all suspension components and they are all in good condition

Just follow the recommendations on the inside of the fuel tank flap and you should be good — I usually add a bit to the recommended pressures as tires inevitably lose a bit over time.

I've driven MBs for 19 years. MB has a habit of printing underinflated values on the fuel cap so that the ride is more compliant (soft). If you want your tires to last, find the MAX permitted cold pressure molded on the sidewall, and inflate the tire to 5-10% less than this stated maximum.
The tire manufacturers know what pressures work best with their tires, while car manufacturers only know what they recommend for ride purposes... They can't have a clue what actual tires you place on the car once you replace the OEM tires at 17-20,000 miles because they wore prematurely.
This will probably start yet another debate on following the gospel of fuel flap propaganda. So be it. I'm getting 35,000-40,000 miles on my tires because I open the Fuel Flap only to put fuel in the tank.

I agree about using the psi on the fuel flap: I add 10%: On my E450 the recommended psi is 33 and I set mine at 35. Like DFWdube I always get more than 30,000 miles on a set of tires. I cannot understand some getting less than 12,000 miles.
However, in my last drive when it was 90 degrees and I was traveling at 70 mph, the tire temperature was almost 130 degrees and the pressure went up to 39 psi. When I got off the interstate and drove on local roads with all the pot holes and imperfections, every bump jarred me. The ride at 39 psi was rock hard and unsatisfactory.
At initial start at 35 psi, overnight pressure with the tires "cold" I find the handling and ride excellent and overall mileage above 34 mpg, actually for a stretch I was getting over 36 mpg. For me this is an excellent compromise.
Just My $.02.

That's usually excessive camber. You need to tell them to adjust it to the minimum of the range, even if that means installing camber bolts.

I have attached some photos but because its wet it docent show it as bad. The first photo is a old tyre it still has some tread left in centre but the edges are wearing the second photo is a new tyre I put on(because the previous one was worn to the cord) if you look at the edge you can see some of the imprint tread has gone.

You should get a tread depth gauge ($5 in US) so you can measure the actual tread depth across the tire section for quantitative results. Then it is evident where the wear is happening. In the U.K., the legal minimum depth for tire tread is 1.16 mm across the central 3/4 of the tread around the whole tire. I replace my tires when the depth is 2 mm.

The wear is inside edge only. That's not low pressure. It's alignment. My previous MB was going through tires that way and they stated the alignment was within spec. But the camber was at the upper end of the range. I had them realign it using the lower end of the camber spec and the problem was fixed. And there was no difference in handling. (It was an AMG so handling was important.)

I also see wear on both edges, which is typical wear for underinflated tires. What tires are these anyway? I've never seen the tread pattern and clearly the two pictures above are two different tires, with completely different tread pattern. I'm guessing these are not the OEM tires. Do they have the same load index as the OEM tires? The fuel door recommended pressures are good for the OEM tires and tires that are close to OEM, but if you go with a completely different tire you may need different tire pressures.

Good point regarding tire brand, OEM and load index.
Tires are constructed in different ways.
I normally use Michelin top performance models on my cars to obtain best grip and stability
- Pilot Sport Cup 2 on my Miata
- Pilot Sport 4S on other cars
Great tires Michelin!

They are imperial, They are all seasons they are different because I had to put a new tire on one of them because it was down to the wire. The load index is 98 y xl
I had them at 225 kpa and that what it says in the fuel door. I will be changing the tires to the same ones next so they will both be brand new I will add more pressure and see if it is any better and if not it is sounding like the camber
