Here’s how to rotate your tires, and why it’s important
If you want your tires to last, you’re going to have to rotate them. Knowing how to rotate your tires is as essential to your car’s regular maintenance routine as changing the oil. It’s also a relatively simple process, although it does require some preparation and the right tools. Here’s how it’s done.
Rotating tires is one of the most straightforward car-maintenance tasks, but it’s also one of the most essential. Tires wear at different rates, and switching their position periodically ensures that they wear more evenly. That means you won’t have to buy new tires prematurely. If tires all wear at the same rate, it also means they respond the same way, ensuring your car’s handling characteristics stay safe and consistent.
Tire rotations should be done once every 6,000 miles or so, and it’s a good idea to check the tread and pressure while you’re at it. You can time tire rotations to correspond with other maintenance like oil changes, and have them done while the car is in the shop. That’s probably the more convenient route, but it’s a snap to rotate your own tires.
Know your tires
The way tires are rotated varies depending on the vehicle, so consult your owners’ manual to find the exact procedure. You may want to mark the tires with chalk to help keep track of them.
Assuming all four wheels are the same size and the tires are non-directional, you’ll want to rotate the tires in a “rearward cross” pattern for rear-wheel drive or four-wheel drive/all-wheel drive cars. In this pattern, the front tires move diagonally, so that the left front tire is mounted in the right rear position, and the right front tire is moved to the left rear position. The rear tires are moved to the front, but stay on the same side.
The pattern for front-wheel drive cars is the opposite. You do a “forward cross” where the rear tires are moved to the front and change sides. Alternatively, you can shuffle the tires in an “X” pattern, where each tire is moved diagonally, regardless of which wheels are driven.
Some cars have directional tires (you can usually tell by the V-shaped tread pattern), and these can only be rotated back-to-front, front-to-back, not side-to-side. If your car’s front wheels and rear wheels are different sizes, you can only rotate side-to-side. If your tires are directional and the wheels are different sizes, the tires have to be removed from the rims and remounted, which is not really something you can do at home unless you have a tire-mounting machine.
Most modern cars have four full-size tires and a compact spare tire, typically called a “donut.” That donut tire should only be driven on in emergencies, but you can use it as a placeholder while rotating your tires. If your car has a full-size spare (meaning it’s identical to the four tires you drive on), you might want to institute a five-tire rotation so that it wears at the same rate as your other tires.
Finally, dually pickup trucks — which have two sets of rear wheels — have their own rotation pattern. Again, this can vary if the front and rear wheels are different sizes, so check your owners’ manual for specific details.
First, prepare to jack up your car. Find a flat piece of ground to work on, apply the parking brake, and place chocks in front of the front wheel and behind the rear wheel on the opposite side of the one you’re working on (the wheels on that side will be off the ground).
You’ll need something to hold up the car while you’re moving tires around. Jack stands are the most straightforward solution, but you can also mount the spare tire on any hub that’s currently missing a tire as a placeholder. If your car has a full-size spare, you may want to rotate it anyway.
Before jacking up the car, you’ll want to loosen the lug nuts, without removing them completely. The ground will provide resistance, allowing you to get them off more easily. If you try this while the wheel is in the air, it will be much more difficult, and because the drive wheels are free to spin, you could strain the transmission.
Most modern cars have a five-lug pattern. The correct way to loosen them is in a “star pattern,” meaning you should start at the top and loosen them in a pattern that draws a star. This prevents the rims from getting warped, and is especially crucial for aluminum or magnesium wheels, which are more fragile than steel rims. If your car has a four-lug pattern, just loosen the nut diagonally across from the one you just loosened.
Lug nuts can be difficult to loosen. One trick is to place your foot on the handle of the wrench and kick it once to crack the lug, then loosen it the rest of the way in a normal manner.
With the lugs loosened but still on their threads, place the jack in the correct position under the car. Every car has specific locations where a jack can safely be placed. Consult your owners’ manual to find the jacking point, and do not place the jack in just any old spot. A seemingly solid surface may not be able to support the weight of the car, or may allow the car to slide off the jack.
Once the tire you want to remove is in the air, you can remove the lug nuts with your fingers. If you’re using the spare tire as a placeholder, get it mounted. Two lug nuts, tightened enough to keep the wheel seated on the hub, should be sufficient, since you won’t be driving on it. Move on to the next wheel and repeat the process.
When you’re putting a wheel back on for real, reinstall all lug nuts and tighten them enough to keep the rim seated on the hub. Then lower the car back onto the ground and tighten them some more. Strictly speaking, you should use a torque wrench to ensure the lugs are tightened to the specific torque specifications listed in the owners’ manual. But doing it by feeling with a conventional wrench should work fine. Tighten the lugs until the level of resistance sharply increases. Don’t over-tighten them, as that can damage the rims. Again, this is especially important for aluminum or magnesium rims.
Once the tires are in their new, correct, positions, you’re all set. Since you’re already playing with your tires, this is a good opportunity to check their pressures and tread depths. Other than that, you should be good to go!
