Long time Falken customer. have driven everything from FK452, FK453, ZE912, ZE950, RT615 and RT615K, STZ04, STZ05 with zero issues on anything. Everyone who is experiencing problems and leaving crap reviews all sound like the issue is either suspension and/or alignment. As a TIA certified installer and shop manager, I can attest to my statements. I am also in no way, affiliated with Falken/Sumitomo nor do I receive any compensation for my testimony.
