What would cause you front tires to sort of bump?

Bumping in the front tires can be caused by several issues, including uneven tire wear, improperly balanced tires, or damaged suspension components. Low tire pressure or a misalignment can also lead to a bumpy ride. Additionally, if there are any issues with the wheel bearings or brakes, these could contribute to the sensation as well. It's important to have the vehicle inspected to determine the exact cause and ensure safe driving conditions.
