2000 Lexus Gs300 Tires

I had these tires a little over 2 yrs, and as of 1 week ago, I saw cracks on the sidewalls on 3 of the 4 tires on my 2000 Lexus Gs300. So I needed to get a new set completely. As 2 were constantly loosing air, and becoming unsafe. I meticulously check the air once a month, and clean them, along with tire protection like Armor All every 2 weeks or so. These have been the worse tires I've ever bought.
