In servicing the 2012 Toyota Tundra, you will need an M14 X1.50 lug nut with a 22-millimeter hex head size. To change a tire, first loosen the lugs but do not remove them entirely. Position the jack correctly to lift the tire. After lifting, take off the lugs completely and remove the tire. Install the new tire and hand tighten the lug nuts before using the lug wrench to securely fasten each one. Lower the jack to return the tire to the ground and then tighten the lugs in a crisscross pattern until they reach 97 ft/lb of torque. Ensuring the proper torque is crucial, as loose lugs can lead to a dangerous situation where the tire may wobble, potentially causing damage to the wheel studs or even causing the tire to come off, leading to a severe accident, especially at high speeds.
The lug nut dimensions for a 2012 Toyota Tundra are as follows: Thread size is M14 x 1.50, hex size is 22 mm, and the overall length is 1.362 inches.
