2021 KIA FORTE Tires Problems

Recall

Bought the KIA 4/192021 from Camelback KIA - Phoenix, AZ. Drove the car home to Green Valley. Approximately 2 months later checked the tires air pressure and discovered that 3 of the tires were at 52 PSI and 1 was at 51 PSI. After checking with a neighbor who owns 2 KIA Fortes with KUMHO tires about the PSI (which is the max PSI located on the sidewall) he said he thought that was wrong. I called Camelback to confirm if that was what they should be kept at - left a message. After 3 failed attempts getting a call back from Camelback and 3 contacts with KIA via their website (no return contacts). I finally contacted KUMHO who emailed me that I should follow the recommendations listed on the car door - 33PSI. My concern is are the tires now dangerous after nearly 3000 miles at 51 - 52...

I purchased my 2021 Kia Forte and have had it for only 6 months. The tires are new and the size are 225/45/R17 Majestic Solus tires both tires front driver side and Back driver side exploded at the same time. I was driving when both tires went exploded at the same time. I thought at first maybe I went over a nail, then when I pulled over I saw both tires had torn in half, the tires looked like they are shredded. I have taken a picture of the road and direction and the street was cleared. I had to take to the kia dealership to have them both replaced. Very upset had to pay for 2 tires. At first they thought I had went over something although when you look at the tires both have the same type of damage. I was driving when this happened I was worried...
