Assist problems of the 2021 Jeep Wrangler

Purchased this vehicle used from Chrysler Dodge Jeep in mesa, arizona. I was told the tires were newer and in great shape they looked to have a good amount of tread on them. However, I had an issue with one tire and the dealership patched it incorrectly making it a safety hazard therefore they replaced one tire with the plug and when I went to a tire place for pressure issues and tps sensor they pointed out the tires were over five years old which means these were the original tires that came with the Jeep in 2021. After only owning this vehicle for two months, I now have to replace all four tires because there is a safety issue with the age and the tread. There was also issues with the steering damper, which they did repair due to wobbling, however there is a slight wobble still because I have one brand new tire from the dealer and three tires that are not new. The dealer refuses to take ownership of the sale of unsafe tires. . Dealer offered three month 3000 mile max care warranty and they still won’t address the tire issue.
