1. How do I pick the right wheels for my vehicle?

Alloy rims are among the most noticeable parts of a vehicle, but they also have a larger influence on how a vehicle performs than many drivers realize. It is for this reason that changing your vehicle's rims can be a great way both to achieve particular performance benefits and to give your vehicle a more striking appearance.

In order to choose the correct rims for your vehicle, you should understand what exactly a rim is, how it fits into single-piece and multi-piece wheels, and how to match rims to tires. Choosing the correct rims for your vehicle also depends on how rims can affect a vehicle's performance and the different rim styles available.

2. How do I install my wheels?

Before they can be used on a car, wheel rims first require that tires be mounted and balanced, as well as installed on the vehicle. To mount the tire, you start by laying the wheel rim flat on the ground with the tire on top and slowly rock it down over the edge of the rim. You may need to use your weight to do this. Once you have half the tire on, the next step is to use a tire iron to lever the other side of the tire over the rim. Be patient, as this can take some time. Once the tire is on the rim, you next insert the valve stem. Then it is time to inflate the tire. It is a good idea to inflate slowly, as the tire can jump when the bead seals against the seat. You may want to fasten it down before inflating.

Once the tire is on the wheel and inflated, installing it on the car is no different than changing a flat tire. You simply remove the old wheel, hang the new one on the lugs and tighten down the lug nuts. Once the wheels are on, you should take the car in to have the wheels balanced immediately.

3. How do I take care of my wheels?

1) Rinse the wheels to remove dirt and brake dust.

2) Rub the wheels lightly with a wet sponge. Starting the process this way will remove most of the residual brake dust and dirt, preventing you from scratching the wheels when you scrub the surface.

3) Remove dirt and debris from alloy wheels with a store-bought alloy wheel cleaner. Avoid acid-based cleaners because they may strip the lacquer off the wheel.

Mix the proper amounts of water and cleaner in a bucket. Read the instructions on the product to find out the correct ratio of water and alloy wheel cleaning solution.

Soak a sponge in the bucket of cleaner and water. Squeeze the sponge over the bucket to avoid wasting the cleaner.

Scrub the wheels with the sponge. Because you already rinsed and lightly rubbed off much of the dirt, hard scrubbing should not damage the alloy wheels.

Use an old toothbrush to clean the crevices in the wheels.

4) Rinse off the solution. Spray the wheels with a hose to remove the cleaner solution. Do one wheel at a time to prevent the solution from drying on the wheels when cleaning all four at once.

5) Dry the wheels with a microfiber cloth or chamois.

6) Add wheel wax to protect the alloy surface. Use a wax made especially for alloy wheels, and apply it at least every 3 months.

4. Do you manufacture custom designs?

YES, CWS has the capability to manufacture custom designs according to a sample or drawing. Please contact us to inquire about custom rim production.

5. What is a bolt pattern?

A vehicle's bolt pattern is the even spacing around the wheel hub of the bolt heads onto which the wheel is fixed. The bolts or studs are evenly spread around a particular diameter which is known as the pitch circle diameter (PCD) and is measured in either inches or millimeters. The hub can also be off-set in a unique way which varies between cars and alters the pattern and shape of the rim.

6. What does offset mean?

The offset of a wheel is the distance from the hub mounting surface to the center line of the wheel. The wheel offset is measured in millimeters and results in a positive, negative, or zero offset. Positive offset is when the hub mounting surface is toward the front or wheel side of the wheel. It is common to find a positive offset in newer and front wheel drive vehicles. Negative offset is when the hub mounting surface is toward the back or brake side of the wheels centerline. A negative offset wheel usually has a "deep lip." With Zero offset, the hub mounting surface is even with the centerline of the wheel.

7. is the difference between hub-centric and lug-centric?

The two commonly used ways to fasten wheels to a hub are lug-centric and hub-centric. In hub-centric designs, the wheel fits snugly against the hub, which provides support along with the wheel lugs. In lug-centric mountings, the wheel lugs center and support the wheel with no support from the hub because of the gap. The easiest way to tell the difference between the two designs is to look at the hub of a hub and wheel assembly. If the hole in the center of the wheel fits snugly against the hub, then it is hub-centric. If there is a gap between the center hole of the wheel and the hub, then it is lug-centric.
