Q: What is the difference between a wheel manufacturing company and a wheel marketing company?
A: Center Line is a true wheel manufacturing company with our own production and design facilities in Southern California. Many of today's wheel companies are simply marketers that import generic cast wheels from China and re-brand the product.

Q: Where are the wheels manufactured?
A: Center Line is proud to have manufactured its wheels in the USA in Santa Fe Springs, California, for over 30 years.

Q: How is a rotary forged wheel manufactured?
A: Center Line has designed a rotary forging press, the only one of its kind in the world, to compress a solid billet of aluminum with 4,000 tons of force, at 300 revolutions per minute. Not only does this process rearrange the aluminum molecules, but it also aligns them in a circular pattern thereby adding strength. As a result, the rotary forged wheel has a much tighter grain structure and is significantly lighter weight than a cast wheel which requires greater mass due to its inherent porosity.

Q: What are the benefits of Center Line's rotary forged wheel vs. a cast wheel?
A:
   1. WEIGHT: The most significant benefit is weight. For your front-wheel drive car, we manufacture 15" wheels weighing approximately 13 lbs. For your truck or SUV, we manufacture 20" wheels weighing approximately 23 lbs (the same weight as a 17" cast aluminum factory wheel!). See the next question for info on the benefits of a lightweight wheel.
   2. POLISH: Due to the density of the grain structure, the polished forged wheel will maintain its luster for much longer than a polished cast wheel which is very porous.

Q: Why is the weight of wheels important?
A: Wheels are rotating mass/unsprung weight. Every 1 lb reduction in rotating mass is equivalent to an approximately 8 lb reduction in static weight. With lighter weight wheels, you will benefit from increased fuel savings, quicker braking, improved tire wear and better acceleration. Always ask about the weight of wheels. Your vehicle is not engineered for heavy wheels. Therefore, it will not perform well if you effectively put four anchors on it!

Q: What is the difference between a one-piece rotary forged wheel and a two-piece rotary forged wheel?
A:
   1. As the name suggests, our one-piece rotary forged wheel is formed in one-piece with no welding. After the billet of aluminum is rotary forged, it is then split-spun to form the rim - all out of the same piece of metal. You will find one-piece rotary forged wheels in the following series: Millennium, HT Comp, Dominator, Tomahawk, Orbital 2000 and Phantom.
   2. The two-piece wheel is manufactured from a billet aluminum, rotary forged center and a billet aluminum rim. The center is then welded into the rim. You will find two-piece rotary forged wheels in the following series: Billet Wheels, Sundance, Sundance Special and Extreme Duty.

Q: Can I buy direct from Center Line?
A: Discontinued styles and stock adjustments are sold direct to the public via Wheel Deals. If you are looking for first-line wheels and your local retailer does not carry Center Line, please contact us at (800) 345-8671 x4.

Q: How do I measure backspace?
A: The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up. Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub-mounting pad of the wheel. This measurement is backspace. The following photo shows three wheels with 2", 3", & 4" backspace.

Q: Does Center Line sell tires or provide tire advice?
A: Center Line does not sell tires. As for advice, we do establish a maximum tire diameter (see next question). However, we do not provide specific tire advice. The best place to go is a tire retailer.
back to top
Q: Is there a limit on maximum tire size?
A: Yes. The limit varies by wheel so refer to the relevant technical specifications for each wheel detailed in the "Wheels - Catalog" section of this website.
back to top
Q: Does Center Line build custom sizes or backspacings?
A: We only build the part numbers listed in the catalog and on the website. You will find the most sizing flexibility in the Billet Series and Sundance Series.

Q: Does Center Line offer a dually application?
A: No. We do not manufacture dually wheels.
back to top
Q: If the wheels I want are not in stock, how long does it to take to build them?
A: Two to three weeks. Slightly longer for chrome.
back to top
Q: Are the polished wheels clear coated?
A: No. Center Line's high polish wheels have a natural, mirror-like finish that will require periodic polishing to maintain (see next questions for maintenance tips).
back to top
Q: How should I maintain my polished and chrome wheels?
A: Washing your wheels with mild soap and water on a weekly basis will help to maintain them. Wash wheels when they are cool to prevent spotting. You will also want to periodically polish the wheels with a non-abrasive, aluminum polish (some recommendations: Eagle One, Mothers, Meguiar's). Absolutely no ammonia-based or acid cleaning solutions on the wheels (or the tires for that matter). Helpful hint from Ron in the Sales Dept: A light coat of car wax on the wheels diminishes the amount of surface contaminants adhering to the wheel.
back to top
Q: How often do I need to polish my wheels?
A: We recommend regular maintenance. If you allow the wheels to dull too far, it will require extra work to get them back to their original luster. Polishing frequency depends on:
   1. Wheel finish: Polished wheels require more polishing - hence the name! Chrome wheels require very little polishing if you regularly wash them.
   2. Weather conditions.
   3. How often you wash the wheels with soap and water.
   4. How you use the vehicle.
   5. Proximity to the ocean.
back to top
Q: What precautions should I take at the car wash?
A: Verify that they will not be using any chemicals, including ammonia-based or acid cleaning solutions, on the wheels (or the tires for that matter).
back to top
Q: Can I run my wheels in the snow?
A: We strongly recommend against running the wheels where road salt is used. The salt will surface pit the wheels. If you have to run the wheels under such conditions, immediately wash them down. If the wheels pit due to negligence, there is no warranty.
back to top
Q: How long is the warranty and what does it cover?
A: The warranty is three years from the date of purchase and applies to the original purchaser only. Proof of purchase is required so hang on to your receipt. The warranty covers workmanship and manufacturing defects.
back to top
Q: What if I damage a wheel?
A: There is no warranty on damaged wheels. In some cases, minor damage can be repaired at a local wheel repair shop (some of these shops advertise in the back of magazines). For wheels featured in the Tomahawk Series only, Center Line offers limited curb damage repair. If you damage a wheel beyond repair, refer to the next question regarding an incomplete set of wheels.
back to top
Q: What if I have an incomplete set of wheels?
A: To ensure that you buy the proper wheel(s) to complete your set, you need the exact part number. The 9 or 10 digit part number can be found on a white label on the outside of the rim (you will need to dismount the tire). If your local retailer is unable to locate the wheel you need using this part number, feel free to contact Center Line at (800) 345-8671 x5 to check our inventory. We may have parts available to make the wheel you need.
