* Year and Model: Different years and trim levels of the Ram 1500 have different wheel wells and suspension setups. Some years are more easily adaptable than others.
* Lift Kit: Almost certainly, you'll need a lift kit (suspension lift) to accommodate 35-inch tires. Without a lift, the tires will rub against the body, fenders, or suspension components. The size of the lift kit will depend on the specific tire size and your truck's configuration.
* Wheel Backspacing and Offset: The wheels themselves need to have the correct backspacing and offset to prevent rubbing. This is crucial even with a lift.
* Modifications: You might need to trim or modify your fenders or other body parts to avoid rubbing, even with a lift and properly offset wheels.
In short: It's highly unlikely you can fit 35-inch tires on a stock Dodge Ram 1500. You'll almost certainly need a lift kit, and possibly other modifications. Before purchasing tires and a lift kit, it's strongly recommended to research your specific year and model of Ram 1500 and consult with a tire professional or off-road specialist. They can advise you on the necessary lift height, wheel specifications, and potential modifications required. Many online forums dedicated to Ram trucks can provide valuable information and real-world experiences.
