Hi everyone! Only had my car from the factory since October. I have the 21 inch alloys on my GLC45 AMG and both the front tires have worn down to 1 mm after 6400 miles use!? More often than not, I’m driving my children around to their various clubs and places they need to be. I know it is a very powerful car, but it hasn’t been driven as such. Just the front tyres alone will set me back £660 to replace!!I can’t be doing that every 6000 miles can I? Has anyone else had the same issue??
