Common tire issues for this vehicle
- Premature tire wear: Due to the weight of the truck, the tires on the Ram 2500 can wear out prematurely. To prevent this, it is important to rotate the tires every 5,000 to 7,500 miles.
- Tire cupping: This is a type of uneven tire wear that can be caused by a number of factors, including improper alignment, worn suspension components, and out-of-balance tires. If you notice tire cupping, it is important to have your truck inspected by a qualified technician.
