Is it time for new car tires? Whether you’ve started shopping around or researching beforehand, wheel shopping requires knowing all the specs of your Jeep’s tires—including the bolt pattern.

Essentially, a bolt or lug pattern is how the bolts are arranged on your car’s wheels. Since no two models are the same, you need to look up your bolt pattern before shopping to make sure you get wheels that will fit your car.

2005 Jeep Wrangler bolt pattern

If you’re a 2005 Jeep Wrangler owner, your bolt or

lug pattern

is 5x4.5 or 5 on 4.5. Here’s how to decode this pattern:

# of bolts x diameter of the circle they form

In this case, your 2005 Jeep Wrangler bolt pattern means that each wheel has five lugs set in a circle measuring 4.5 inches in diameter.

Before you go buy new wheels for your car, you need some other measurements to get the best-fitting wheels. These include your Jeep wheel size, stud size, tire offset, measurement of the center bore, and torque specifications.

Here are the specs you need to know for a 2005 Jeep Wrangler:

Factory wheel size: 15”

Stud size: 1/2"x20 (1/2 inch stud with 20 threads per inch)

Offset: 25 mm

Center bore: 71.5 mm

How to measure your Jeep Wrangler’s bolt pattern

The Jeep wheel specifications listed above are generally all you need to know to get the right wheels for your car. However, some drivers prefer to measure themselves to ensure they have the right Jeep Wrangler bolt pattern. Fortunately, this is a quick and easy process.

To measure you’ll need a measuring tape or ruler. Then, follow these steps to get your Jeep’s bolt pattern:

Count the number of bolts—this is the first number in your bolt or lug pattern

Measure from the lug hole’s outer edge to the center of the bolt directly opposite—this is the second number in the bolt pattern

Keep in mind that your Jeep has five lug bolts. So when measuring the distance between bolts, know that the opposite bolt is not directly across from the one you’re starting with! Instead, measure from either of the nearest bolts to the center.
