There are 3 owner-reported tires & wheels complaints for the 2004 Mercedes-Benz CLK-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I purchased 4 new tires, my car calls for a staggered fitment (225/45R17 DOT# 1RB7RR9872922 and 1RB7RR9811521 up front and 245/40R17 DOT# 1RB8NR981112 and 1RB8NR9811022 in the rear). Upon returning home, I noticed the tires were installed backwards with the wider ones up front. This will cause the tires to rub the shock absorbers and will lead to tire blowouts and likely much more damage to my vehicle or injury to myself and or others. I called Firestone when realizing this and they said to bring it back and they would fix it. Had I trusted the professionals to do their job correctly and not double checked their work I would have blown out the two front tires within a few thousand miles; fortunately for me, I do not trust anyone to work on my vehicles but myself. Coincidentally, Firestone has an advertisement in their lobby that says "Fixed right or its free guarantee. Ask for details." When I asked the store manager about the sign, I was literally laughed at and told I am not getting free tires. They need to be held accountable for their advertisements and either refund me the purchase amount or they need to remove / edit their signs likely at all 22,000+ locations nationwide.
