Kia Optima Bolt Pattern (2000-2022)

The Optima is a reliable, low cost car by the popular Korean automaker, Kia. Kia has come a long way. They used to be low-quality vehicles that you could buy if you didn’t have a lot of money. Now they are pretty high quality vehicles that you can buy if you don’t have a lot of money.

In this article, we will go over the Kia Optima bolt pattern. We will also elaborate further on the car’s center bore, thread size, and the various tire and rim combinations that were available across several generations. 

Kia Optimas that were manufactured between 2008 to now have a bolt pattern of 5×4.5 inches (5×114.3mm) and a center bore of 2.64 inches (67.1mm). The Kia Optima uses 5 lug nuts with a M12 x 1.5 thread size. These lug nuts need to be tightened down to 65.1 – 79.6 ft-lb (88.3 – 107.9 Nm) of force. Kia Optimas that were made between 2000 and 2007, on the other hand, use a 4×4.5 inches (4×114.3mm) bolt pattern. 

This information, while useful, doesn’t paint the complete picture. So, you can reference the table below for a little more information, and continue reading the article for a lot more info regarding the Kia Optima bolt pattern and its tire sizes.

Properly Tightening The Bolts

The most recent Kia Optima models use 5 lug nuts, but some of the older models use 4. Either way, these nuts have to be secured in a specific criss-cross pattern. Also, they have to be tightened to a specific torque level. You can, of course, find this information in your Kia Optima user manual, but we went ahead and put it here for you for the sake of convenience. 

The first step is to tighten your lug nuts with a hand wrench. But do not tighten them all the way, just put them half way on. If you go ahead and tighten them all right now, you won’t be able to get them all to the right torque settings. Also, it could cause vibration and alignment issues that could, at the very least, become serious. 

After that, you can go over each one in a criss-cross pattern and tighten it to the proper pressure. For the most recent Kia Optimas, the lug nuts need to be tightened to anywhere between 65.1 and 79.6 ft-lbs.

NOTE: It’s super important to do a basic travel test. A good way to do this is to drive for around 30 miles and then check the torque on all of your lug nuts. If any of them are loose, tighten them down and drive another 30 miles or so and do the test again. After the second test, check your lug nuts again. If any of them come out, it means your rim is more than likely warped. If that’s the case, you’ll need to replace it.

When Or Why To Rotate/Change Tires

Tires generally last around 60 to 75 thousand miles. This, of course, depends on many factors such as the roads you drive on, your riding style, etc. It’s not just all about miles though. Time is a huge factor here. Remember, the rubber in tires is vulcanized, so it will last a lot longer than any natural rubber will. 

The thing is, vulcanization is not a perfect process and tires will still dry rot after a while. So, if your tires still have plenty of tread but are over 5 years old, it’s time to replace them. 

You should rotate your tires long before they need to be replaced. As a matter of fact, if you rotate your tires at regular intervals, they will last way longer than they would otherwise. Rotating your tires is a simple process and it will save you money and make your car safer to drive. For the Kia Optima, the best time to rotate your tires is about every 7,500 miles. To do this, it’s simple. All you have to do is move the tires that are on the right side of the car to the left side of the car. In the process, also flip the front and back tires. 

Conclusion 

The Optima is known to be a highly reliable and practical vehicle. No vehicle is perfect, however, and eventually parts wear down and something’s gotta give. It’s times like those where you really need to know the Kia Optima bolt pattern. 

If you have a Kia Optima that was made from 2008 through 2020, it has a bolt pattern of 5×4.5 inches (5×114.3mm) and a center bore of 2.64 inches (67.1mm). It uses 5 lug nuts that have a thread size of M12 x 1.5 and need to be tightened down to between 65.1 and 79.6 ft-lb (88.3 – 107.9 Nm). For older Kia Optimas that were made between 2002 and 2007, the bolt pattern is 4×4.5 inches (4×114.3mm), everything else is the same. 

We hope this article helped you learn more about the Kia Optima bolt pattern. Thanks for reading!
