Introdução

Tire rotation ensures even wear on the tires. Front and rear axles support different weights, and will wear differently. Rotating tires allows for even wear on a set of four tires, maximizing the lifespan of the set.

You should rotate your tires every five thousand to ten thousand miles to reduce uneven tire wear.

Place the hydraulic floor jack under the vehicle until the saddle is directly under the crossmember.
  • Place the hydraulic floor jack under the vehicle until the saddle is directly under the crossmember.
