Additional considerations
Aftermarket wheels and seating variations
Some aftermarket wheels use different lug nut sizes or seat styles. Always confirm the exact specifications with the wheel manufacturer and ensure compatibility with your Ram 2500’s hub bore and bolt pattern before ordering replacements.
Installation tips
Use the correct torque and in a crisscross pattern to ensure even seating. Avoid applying anti-seize compounds to lug studs or lug nuts, as this can alter the effective clamping force. Re-torque the lug nuts after the first few driving miles if recommended by your manual or wheel supplier.
