Jeep owners often like to put in the work to know their vehicles inside and out. That way, they can adjust and alter the ride to fit their needs. Whether you’re aiming for a monochromatic look or just need the biggest, baddest tires for your off-roading escapades, changing your Jeep’s tires is a common car mod.

Before you can swap out the old for the new, however, you’ll need to know their Jeep’s bolt pattern. And as the

1998 Jeep Wrangler bolt pattern

The

1998 Jeep Wrangler bolt pattern

is 5x4.5. If you’re staring at those numbers and are coming up at a loss, don’t worry. We’ll break them down here.

Bolt patterns, also known as lug patterns, are typically expressed as the number of bolts x the diameter of the circle they’re arranged in. So in the 5x4.5 bolt pattern case of the 1998 Jeep Wrangler, each wheel has five bolts arranged in a circle with a 4.5-inch diameter.

But don’t scoot off just yet! In order to shop and swap for new wheels, you’ll need a bit more information: the factory wheel size, the stud size, the wheel offset, and the center bore measurement. Those are as follows:

Factory wheel size: 15’’

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

Offset: 10mm-31.75mm (depending on the trim level)

Center bore: 71.5 mm

How to measure your 1998 Jeep Wrangler’s bolt pattern

All those measurements we just laid out should be enough for you to shop for some shiny new 1998 Wrangler wheels, but that’s not to say that you can’t measure for the bolt pattern yourself! If you’d rather not take our word for it or you’re just curious, you can measure your 1998 Jeep Wrangler bolt pattern relatively easily. Here’s how.

Grab something to measure with—a measuring tape or ruler will work just fine. Place the starting end of your measuring device at the outer edge of any of the five bolts. Measure straight across to the center of the opposite bolt.

Since there are an odd number of bolts, there won’t be a clear “opposite”—just choose either of the bolts right across from the one you started at.

Whatever measurement you end up with from one bolt to the other is the diameter, or the second value in the bolt pattern. Count the number of bolts, put it in front of the diameter, and you have your lug pattern!
