I’ve done 23k miles since new over a 2.5 years and have discovered that my Toyo tyres on 2WD CX 5 are cracking around the tread length. This applies to the front and rears. Have concerns about safety even though there is plenty of tread depth left.
Have had to replace one of them already. Anyone had similar problems?

I've heard many "experts" claim the manufacturers use a poor quality of tire on their new autos. It sounds like it is true in your case. My Mazda is only 7 months old. but I watch the tires closely. I'm afraid it is what goes on these days.
