NHTSA Complaint #11694554 — 2025 RAM 1500

My speedometer is off by 9mph while traveling 70mph. When I purchased my vehicle new from the dealer, they had already installed bigger tires. I noticed that my speedometer showed 70mph and my gps showed 79mph. I took it to the dealer and they showed me where they had programed the new tire size in the computer but it did not adjust my speedometer. The service manager said its withing normal limits. I have been pulled over twice for "speeding" when my speedometer said 58mph and the cop said he clocked me at 65mph. I feel like this could be a saftey issue for potentially speeding in unsafe zones such as construction or school zones without knowing it.
