What's wrong?
The tires on 2014-2015 Ram 4500 and 5500 cab chassis trucks with the 6.4L HEMI engine are rated for a maximum speed of 87 mph. The engine control unit also has a speed setting that limits how fast the truck is allowed to go. Those two limits are supposed to match so the truck stays within the tire manufacturer's rating.
On affected trucks, the speed setting was calibrated to 106 mph. Ram traced the problem to a calibration carried over from 3500 cab chassis gasoline trucks, where that higher setting was correct. On the 4500 and 5500 cab chassis trucks, that setting lets the vehicle exceed the tire speed rating, putting the tires outside the limit they were built to handle.
There is no warning sign before failure. The truck is not expected to feel different before the tire is driven beyond its rated speed.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Driving faster than the tires' maximum speed rating can cause sudden tire failure and increase the risk of a crash. There is no warning sign before failure, so keep speed within the tire rating and schedule the software repair soon. Repair is free at any franchised Ram dealer.
What should I do?
- Check your VIN to confirm your 2014-2015 Ram 4500 or 5500 cab chassis truck is included in this recall.
- Contact a franchised Ram dealer to schedule the free ECU software flash that limits truck speed to the tire rating.
- Reference recall number 15V290 and Ram recall R17 when you call.
- Bring the owner letter if Ram sent one, and ask the dealer to confirm the software update is complete before you drive away.
- Keep speed at or below 87 mph until the repair is complete because sudden tire failure increases crash risk above the tire rating.
What happens at the repair
At the dealer, a Ram technician updates the electronic control unit software so the truck's governed speed is limited to 87 mph, matching the tire speed rating named in recall 15V290. The software correction and labor are free under the recall. If you already paid out of pocket for a related repair before the owner letter, the reimbursement program covers documented expenses. Send the original receipt or other proof of payment as directed in the owner letter, or bring that paperwork to the Ram service desk for help.
