How To Change Bolt Pattern Without Adapters? Step By Step

Changing bolt patterns is not an easy feat for numerous drivers and even professional mechanics, requiring much automotive knowledge.

But how to change bolt pattern without adapters?

This task seems more difficult than the usual method involving a wheel adapter, but there is no need to panic because the easy-to-follow guide is waiting for you to explore.

Keep scrolling down for further information!

What Is A Bolt Pattern And How To Measure It?

The bolt pattern determines the number and position of bolt holes on your vehicle’s wheels, which align with the studs on the mounting hubs.

Somm car models’ wheels are equipped with multiple bolt patterns, which are referred to as dual drill or dual drift.

Thanks to this feature, one wheel could fit numerous vehicle applications.

The bolt holes are spaced evenly around a bolt-hole circle. And the process of measuring them is necessary.

First, you must count the exact number of bolts on a wheel before estimating a circle’s diameter that runs through each bolt’s center.

After gaining these two statistics, put those two together and get an accurate measurement of your bolt pattern. For instance, “5 x 114.3MM” could be expressed as “5 by 114.3”.

This implies a 5-lug bolt pattern with a circle’s diameter of 114.3 millimeters.

How To Change Bolt Pattern Without Adapters?

To change bolt pattern without adapters, you can pick a wheel with a correct bolt pattern, measure the offset to ensure a right fit, mount the wheel, and perform a final fitment test.

Pick A Wheel With A Suitable Bolt Pattern

It is important for you to purchase a wheel that is suitable for your automobile. This process is a prerequisite for upcoming steps, so you should pay close attention.

You should ensure to tick all the boxes below:

  • A new set of wheels must have similar diameters to those of the former wheels. Even a small change can affect their speedometer accuracy.
  • Examine the width of your vehicle’s wheel as a way of guaranteeing its appropriate tire fitment and see whether it is compatible with the suspension or not.
  • Opt for an apt wheel’s offset. A short offset will prolong the distance between a wheel and your automobile’s centerline.
  • Check the central bore diameter to examine its compatibility with your car’s hub.
  • Look at its materials as well. Some are made of chrome coating, called premium wheels while others don’t.

Measure The Offset Of An Existing Wheel

The next step requires you to gain the exact measurement of a wheel offset. Faulty data can lead to improper compatibility of your vehicle’s tires.

  • Pinpoint the position of a wheel’s mounting side by laying your wheel on flat ground and counting its distance towards the wheel’s inner edge.
  • Locate the tire’s centerline by checking its width.
  • Obtain the offset value by using a specialized tool to subtract the centerline’s distance from a mounting face.

Ensure The Wheel And Tire’s Compatibility With Your Vehicle

Checking the wheel and tire compatibility involves the examination of several devices and criteria, such as the wheel size, rubbing matters or speedometer accuracy, etc.

  • Measure tire and rim sizes again to verify that they are suitable for your vehicle. You could consult the manufacturer’s manual or estimate them with tape.
  • When testing your car’s new wheels, determine any clearance and rubbing issues that are likely to arise.
  • Ascertain that the error value of the overall tire’s diameter does not surpass 3 percent, leading to a greater speedometer accuracy.

Mount The New Wheel And Tire

It’s time you install the new aftermarket wheel and tire, and the following are viable tips that you must take close notice of.

  • Prepare necessary tools, like a torque wrench, a plier, etc. And don’t forget protective garments, such as gloves and eyeglasses, to protect your safety.
  • Tighten the nuts and bolts of your wheel to a recommended torque value based on the manufacturer’s manual.
  • Use a criss-cross pattern to make all the lug nuts tight and fit your wheel. This approach helps spread the pressure on the wheel hub evenly, preventing one part from tolerating too much stress.
  • Suppose the central bore’s size exceeds your automobile’s hub diameter. In this case, you are advised to use a hub-centric ring to fit its larger size.

Test The Wheel’s Proper Fitment

After tightening your wheel’s lug nuts and bolts, you must test-fit them to see whether they can pair with your automobile and make a smooth rotation.

  • Steer your wheel and tire for one round and turn them to both sides with the purpose of checking for any rubbing issues.
  • Notice the interference between the tire and your vehicle’s body components and implement prompt measures.
  • Sit on your automobile and switch the ignition key on for a test drive. While driving, you should notice any improper handling or vibrations through the car’s floor.

What Are Some Mistakes To Notice?

While measuring the exact bolt pattern of your car’s wheel, you are apt to make mistakes that can give rise to an inaccurate result. And here are some you’d better avert.

Opting For An Improper Measuring Technique

Unsuitable devices and tools might affect the process’ final result. Just a slight difference leads to a false measurement of the wheel bolt pattern.

Following are tried-and-true tips you should notice closely.

  • It is strongly recommended to prepare a lug pattern caliper and gauge.
  • Start to measure the pattern from the outermost edge of your bolt to its center.
  • Check how many bolts before estimating the distance.

Choosing A Wrong Tire And Wheel Setup

The wheel and tire of each car do not bear a resemblance.

So if you want to purchase new ones, you’d better consult the advice of qualified mechanics or check the manufacturer’s manual, thereby choosing the correct setup.

Below are other instructions for you.

  • Buy wheels with the correct offset, bolt patterns, and sizes.
  • Avert going too small or too large, given your selection of tire and wheel.

Ignoring The Test-Fitting

A test fitment ensures you have a correct choice of wheel setup and complete the above steps properly. I hope the following tips will help you out.

  • Make an installation of only one wheel and tire simultaneously.
  • Hand-tighten the bolts carefully.
  • Use a hydraulic lift to raise your car before checking your car’s wheel and slowly lower its height on the ground.
  • Verify adequate clearance.
  • Drive test your wheel, along with the tire.
  • Examine your brakes and keep an eye on the suspension clearance.

Not Torquing The Wheel Bolts Tightly Enough

If you don’t torque the nuts and bolts well or in the opposite direction, they can easily loosen, causing your wheel to fall out and entailing serious accidents along the road.

  • Prepare a good torque wrench.
  • Tighten the nuts clockwise or in a rear pattern.
  • Re-torque the nuts and bolts after driving the first 50 to 100 miles.

What Tools Do You Need To Change The Bolt Pattern?

Changing the wheel’s bolt pattern only requires fundamental tools and devices, like a drill, a torque wrench, a tap set, and a drill bit.

It would be best to prepare a flashlight in an environment that lacks natural light or dims in the darkness.

Is It A Challenging Task To Change The Bolt Pattern?

Yes. To amateurs or inexperienced mechanics, this process can be a nightmare because it entails the most accurate tapping as well as drilling.

So suppose you lack knowledge about this automotive aspect, you are not advised to perform the procedure at home.

In an emergency, take your automobile to a reliable garage or call a professional mechanic, and he will help you accomplish this task.

Will Altering The Wheel Bolt Pattern Impact The Car’s Performance?

If your car’s bolt pattern is not torque properly, and the wheel is prone to failure, changing the bolt pattern is pivotal to ensure the optimal performance and smoother ride of your vehicle.

Yet, as mentioned earlier, please pay close attention to the common mistakes that many people face so you stand a greater chance of undertaking this task more successfully.

The Bottom Line
