NHTSA Complaint #11672594 — 2018 RAM 3500

August 2024, arrived to Discount Tire, Lee Store in Prescott Valley, AZ. Showed salesperson my Ram 3500HD, also reflected on my account with them. Salesperson ordered 122Q instead of 122QE for 1 ton truck. This was intentional as 4 months later (December) brought in for excessive wear, manager on duty declined warranty and tried Toyo who required I go back to dealer placing me into procedural loopholes and denial of service from both. This week noticed drastically worse and demanded reopening of December claim. Same dealer manager on duty did nothing, reached out to Toyo again. At no point did anyone (Toyo, salesperson or Discount Tire Manager) admit the mistake as kept repeating premature disintegration of tread and safety issues. After continuous delays, knowing vehicle is 3500HD and these are not E-10 no viable actions taken to secure my safety. I researched further and found the wrong tires were installed on my vehicle. Tire company knew and withheld this vital piece of information and failed to take action when reported back in December and again in July. Tire on vehicle: Toyo Open Country CT - LT275/70R18 125/122Q. I have the back and forth emails for this month's and December. I've enclosed the one tire (purchased 4).
