Wheel Alignment
Tire alignment, also known as wheel alignment, can help your tires perform properly and help them last longer. It can also improve handling and keep your vehicle from pulling in one direction or vibrating strangely on the road.
What Is Tire Alignment?
Alignment refers to an adjustment of a vehicle’s suspension – the system that connects a vehicle to its wheels. It is not an adjustment of the tires or wheels themselves. The key to proper alignment is adjusting the angles of the tires which affects how they make contact with the road.
How Do I Know If I Need A Tire Alignment?
There are a couple ways to tell if your car needs a tire alignment. If you've noticed one or more of these indicators, you should have your alignment checked by a licensed service technician immediately.
- Uneven tread wear.
- Vehicle pulling to the left or right.
- Your steering wheel is off center when driving straight.
- Steering wheel vibration.
Tire Plugs
So, you have a flat tire or one that’s leaking air. It’s not the end of the world. Luckily there are safe and cost-effective ways to properly repair most tire punctures. The purpose of this article is to show you the difference between a safe, permanent repair and a temporary string, plug or patch repair.
According to the National Highway Traffic Safety Administration (NHSTA) and the Tire Industry Association (TIA), the only method to properly repair a tire puncture is to fill the injury with a repair stem and back the stem with a repair patch. This is commonly known as a combination repair or a patch/plug repair.
Patch/plug repairs are most often performed using a one-piece repair unit that combines the repair stem and cap (or patch) into one unit. However, special circumstances may require the use of a two-piece combination repair (ex. If the angle of the puncture exceeds 35 degrees). The repair is then permanently bonded to the inside of tire and through the injury channel using a cold, chemical vulcanizing process. The repair essentially becomes part of the tire, creating an air-tight seal that keeps air in and moisture and contaminants out (more on this procedure below).
String Repairs are Temporary Repairs
Emergency roadside plug repairs are NOT intended to be a permanent tire repair. Plugs and string repairs are designed to get you back up and rolling long enough to get home or to the nearest service center to perform a proper tire repair.
The common misconception with plug and string repairs is that because they hold air, they are safe to use. While it is true that many plug repairs do a great job of keeping air in the tire, that’s only part of the equation. Because they’re not completely sealing the injury, plug repairs may allow air and moisture to penetrate the body of the tire. Over time, this could lead to a dangerous (or even deadly) blowout.
Flat Tire Repair
A patch-only tire repair leaves your tire susceptible to damage.
A tire repair that uses only a patch is also NOT considered proper or safe. A properly installed patch will do a great job of allowing the tire to hold air. However, similarly to the plug-only repair, the patch does not fill the injury channel. Therefore, air and moisture could seep into the tire from the tread surface and eventually damage the tire.
The Proper Tire Repair Process According to Industry Guidelines
Only a proper patch/plug repair completely seals the puncture from inside the tire and through the entire injury channel. There are a few extra steps necessary to perform a proper tire repair in accordance with industry guidelines. We’ve developed a simple acronym to help organize and remember the steps: R.E.P.A.I.R.
- Remove: To begin, the tire must be removed from the wheel assembly. This allows for a thorough inspection of both the inside and outside of the tire.
- Evaluate: With the tire removed from the rim, the puncture can be thoroughly evaluated to determine the size and angle of the injury. It can also be determined if the puncture did any significant damage to the cords or belts.
- Prepare: Once the tire has been determined to be in good enough condition to repair, it is time to prep the rubber surfaces to remove any damage and contamination to allow for maximum repair unit adhesion. First, the injury is drilled out using a carbide cutter to strip away and damaged cords or belts. Next, the inner liner is cleaned and buffed to a slightly rough texture. This also helps maximize adhesion of the patch/plug repair.
- Apply: The next step is to apply vulcanizing fluid through the injury and to the buffed area of the inner liner. It is then allowed to air dry for 5-10 minutes.
- Install: The one- or two-piece repair is installed through the injury channel and the patch portion is thoroughly stitched to the inner liner using a tire stitcher to completely push out any air that may have gotten trapped under the repair. The over-buffed area of the inner liner is treated with a thin layer of rubber sealant, and the excess repair is trimmed to approximately ¼” above the tread surface.
- Return to Service: The tire is now ready to be remounted to the rim, inflated, balanced and mounted back on the vehicle.

Rim Straightening:
Uncorrected vibrations will not only destroy your tires, it can cause serious damage to both the steering and suspension systems of your vehicle. OBT LLC will take your wheels and fix this issue with our straightening service. We will restore most out of round or bent wheels back to balanceable trueness in one hour or less.
Wheel Polishing
Wheel polishing can make a world of difference. Remove swirls, light scratches from clear coated wheels, and polish aluminum and chrome with the best selection of mini and micro tools in the industry.
Powder Coating:
Powder coating is a metal finishing process that offers a far more superior finish than alternative finishes like paint. Powder coat offers greater durability, impact resistance, and improved wear characteristics in comparison to other finishing options. In addition to the improved durability, powder coating is offered in a great variety of finishes. Finishes include the basic gloss, semi-gloss, and flat finishes to unique texture, wrinkle, hammer tone, and candy finishes. There are thousands of colors available to choose from and if a specific color is needed then custom color matches can be made to match. Powder coating also provides quick turnaround times as once it is cooled back to room temperature it is ready for use. Feel free to call or email us to discuss your needs and the options available to you.
Tig Welding:
Hitting a pothole may not only bend your rim, but also may cause a hairline cracks which causes your rim to leak air. Although usually cracks are on the inside of the rim, sometimes the impact is so hard that an entire chunk of the face is broken off! Using TIG welding combined with our trained welders, digitized machining, we can restore your rims and repair them for a fraction of the price of buying a new one.
Tire Rotation
Even if your car is properly aligned, tires still need to be rotated for optimal wear performance and maintenance. Rotation counteracts the uneven wear characteristics of each wheel position on the vehicle. How often should you do it? To maximize tire tread life, follow the recommended rotation schedule in your vehicle owners manual. If there is not a recommendation from the vehicle manufacturer, then rotate your tires every 5,000 to 7,000 miles by taking your car to a trusted tire dealer or automotive service center.
Maintain Proper Alignment
If your car's wheels are out of alignment, your tires will wear unevenly, which can lead to early tire replacement. Also, a car out of alignment could signal other mechanical problems that may affect tire performance. For the best results, choose a shop that uses accurate computer-assisted machines, and ask for a printout of the adjustment angles to keep with your service records.
Check Your Balance
Tires and wheels that are out of balance don't just cause annoying vibration. Uneven tread wear may also result, further reducing your ride comfort and leading to earlier tire replacement. A shop with an electronic spin balancer can help smooth things out.
Front-Wheel Drive and Rear-Wheel Drive Vehicles
Front-wheel drive vehicles place braking, steering and driving forces on the front axle tires. Rear axle tires receive primarily braking forces, resulting in a much faster wear rate for the front axle tires.
Modified Cross Rotation
Notes:
Following rotation, adjust all tires to the vehicle manufacturer’s recommended inflation pressures. Always torque lug nuts or lug bolts to manufacturer’s recommended specification.
Four-Wheel Drive
Straight Rotation
Five & Six-Tire Rotation
If your spare tire is a matching full size tire (as opposed to a temporary spare) and you want to keep it in rotation, move the spare to the right rear position. Then place the tire that would have gone to the right rear in the spare position.
If your vehicle has dual rear wheels the rotation pattern looks like two triangles, one on the driver’s side and one on the passenger’s side. For each side, move the outer dual tire to the inner position, the inner dual tire to the steer position and the steer tire to the outer dual position.
Notes:
Never include a temporary spare tire in the rotation. Directional tread patterns must be rotated front-to-rear only so the direction of the rotation does not change.
