2021 Kia Forte

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 PSI? I have been told that driving with the tires at that max PSI causes excessive wear in the center especially in the Arizona heat. Neither Camelback or KIA has ever contacted me - 6 total attempts. Tires are 225/45 R17 Kumho Majesty Solus.

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 I could have caused an accident. Please everyone be safe and careful. I am out money because of these tires.. New car no reason for this to happen. These tires need to be reinspected.
