Before You Begin

Installation by a specialist service technician is extremely suggested. Please read this whole guide before the installment and make sure the fitment is right for your application.

Always make use of brand-new lug screws when setting up brand-new wheels.

Never utilize lubes on lug bolts or lug openings. This may lead to loss of torque or failing of lug screws.

Do not make use of air impact wrenches to tighten your lugs. This might lead to the weakening of your lugs, creating them to fall short while driving.

Step 1 - Lug Screw Fitment List

The first and most important action to haul bolt installment is ensuring you have the ideal fitment for your vehicle and wheel application. Failing to use the proper lug screws will certainly trigger dangerous driving problems that can lead to wheel loss while driving. Only use lug screws made to fit your car and wheel application.

Utilize the list below to validate your lug screw fitment before setup, or contact a Driven Products Fitment Expert for assistance.

Lug bolts with an M14x1.5 B thread dimension are required for the lug holes on a 2017 Mercedes-Benz C-Class 300. The lug bolt's thread size needs to match the screw apertures on your car.

According to the type of wheels you have, there are three common lug bolt sitting styles: (1) cone or conical seat, (2) mag or shank seat, and (3) distance or ball seat. The lug bolt's seating design must match the wheel lug seat. Utilizing the incorrect seating design will certainly create resonance, loosening of lug bolts, or damage to your automobile.

Carry Bolt Style: Various sorts of wheels need various designs of lug bolts. For example, many aftermarket wheels will require a tiny lug bolt, while many manufacturing facility design wheels will need a bigger lug bolt. Many small-diameter lug bolts will be hazardous to install on factory wheels.

Shank Length: The lug holes on your car will need a particular lug screw shank length. The shank length will certainly be the size of the screw bolt, starting at the seat's base to the bottom of the bolt.

Minimum Thread Engagement: The thickness of a wheel can vary from factory to aftermarket wheels. Therefore, it's vital to validate that the lug bolts correctly engage the strings inside your lorry's lug openings. Refer to our minimal string involvement graph to determine the variety of turns, or deepness of involvement, normal for your application.

Step 2 - Prepare For Installation

Now that you have validated lug screw fitment, it's time to prepare your vehicle for installation and eliminate your present lugs.

Park on a hard, level surface and use the emergency brake.

Loosen up the lug bolts one-quarter turn, yet do not remove them from the wheel.

Increase your automobile, complying with the process described in your automobile proprietor's handbook.

Safeguard the wheel and also eliminate the lug screws, then the wheel.

Action 3 - Install Your Lug Bolts

We advise using the RIST approach of lug screw setup, which the Tire Market Association describes in its Automotive Tire Solution training program. The RIST approach involves: (R) Removing debris from mounting surface areas, (I) Inspecting elements for damage or too much wear, (S) Snugging the lugs in a star pattern, and (T) Torquing to manufacturer requirements. Comply with all instructions in the order provided.

Tidy and examine all bolt hole threads and place surfaces before installation. Lines should not be lubricated and should be free of deterioration, rust, burrs, cracks, and damage.

Hold the wheel up against the blade plate and match the screw circle of the wheel to your automobile. The wheel must make complete contact with the breeding surface of the home plate. You might need the assistance of an added hand to hold the wheel for the list below action.

Mount your lug bolts and tighten with your hand in a celebrity, or crisscross, pattern until you can not hand any longer. Describe our wheel torque series graph to identify your installment's proper way and sequence.

As soon as all lug bolts have been tightened to fulfill minimum string engagement and your wheel is resting flush against the breeding surface, reduce the car to the ground and tighten all lug screws to the proper torque specifications shown in your vehicle proprietor's manual. We suggest utilizing a calibrated torque wrench for this action. Apply torque equally by repeating the celebrity or crisscross pattern until the preferred torque is reached.

Constantly re-torque your lug screws after the first 25 miles of use each time the lug bolts are eliminated and set up. Failing to re-torque could result in unsafe driving conditions.

Frequently Asked Questions (FAQs).

Can you drive a car and truck with a missing out-on lug bolt?

If you're missing out on a lug screw, you must have it replaced asap. A missing out on a lug bolt could bring about harmful driving problems because of the extra force applied to the wheel. This stress can damage the wheel bearings and cause various other lug screws to stop working, leading to the failure of the revolution while driving.

Can loose haul bolts create damage?

When a lug screw is loose, the clamping forces are rearranged amongst the continuing lugs. The loosening up process will certainly increase with each lug that loosens up, creating the overall clamping power to go down and the force continuing to be lugged to increase. The lugs can then fracture, accelerating the process if not spotted and corrected swiftly.

Exactly how limited should you tighten your lug screws?

Lug bolts must always be set up using a calibrated torque wrench to the torque specs displayed in your car proprietor's guidebook. Under and over torquing are common when air influence wrenches are utilized.

Why do wheels come loose?

Loose wheels are commonly the outcome of an improper or negligent setup. Strings need not be oiled and must be without rust, corrosion, burrs, fractures, and damages. Failure to comply with the torque requirements in your automobile proprietor's handbook, correct wheel torque sequence, or regular torque checks have been cited as causes of loss of securing pressure on lug bolts.
