Warranty

 Due to the inherent abuses in racing, all of our wheels are warranted for structural and finish defects for just 90 days from original purchase date.  Any damage caused by external forces are not warranted  (race brake pads, chemicals, stone chips).  Many people buy our wheels to use on both street and track and we have had great feedback regarding dent resistance.  Bent or curb rashed wheels are not covered under warranty.  In fairness to our customers, wheels sent to us outside of the above conditions will still be considered on a case by case basis.

 

 Most drivers know track and competition use is hard on parts and cars and those parts including wheels will fail from time to time.  All wheel companies suffer from some failures and cracked product, in some instances causing damage and possible injury or death.  This very real risk should not be hidden from customers and is a responsibility they take when engaging in such events.


Since competition and track days are inherently prone to causing parts wear and vehicle damage, such use is not covered by any warranty expressed or implied for any of our wheels.  Use of CTW Motorsports wheels or any other product we sell or distribute is done so at your own risk.  CTW Motorsports assumes no liability for injury, death, or losso fo property as a result of using CTW Motorsports or other branded product under any usage conditions, including but not limited to autocross, drifting, time trial, HPDE, or track use.  We all know racing is hard on parts and cars, and parts will fail.  This is reiterated here for added emphasis. The sender is responsible for shipping on wheels sent for warranty evaluation.  Shipping is not covered with warranty service.

 

CTW Motorsports reserves the right to make changes in design, materials, and specifications or to make product changes without incurring liability or obligation with respect to similar products previously manufactured.  We do strive to continuously improve our product and reserve the right to do so.

 

TIRE RACK SAYS THIS ABOUT WHEELS IN GENERAL on their website:  (we wanted a third party neutral opinion about all wheels, and this is a direct, unmolested cut and paste besides some underlining we thought was important)

 

Using Alloy Wheels on the Track

For real driving enthusiasts there aren't many feelings that equal the excitement of running laps on a race track at their vehicles' limit. And while race tracks were once only accessible to race prepared cars, today many car clubs and professional driving schools allow drivers to learn more about high performance driving as they run their street cars (with relatively few modifications) on the same tracks as their racing heroes. For that matter it is not unusual to have more track time (enough to drive several hundred track miles per day) at a typical club event or driver's school than most actual race weekends. And while it's common sense that track use will increase the wear on a car's tires, brakes and shocks, there are less obvious critical components that also wear out ...like its wheels! Yes, wheels do wear out...or better stated, they fatigue.

 

Because wheels are so critical to the driver's safety, top racing teams visually inspect their wheels at the track, monitor the total number of hours they are used, and crack test them on a periodic basis. Any wheel that shows signs of fatigue or age is discarded and replaced. For that matter Indy Car sanctioning bodies require that their race participants' wheels meet strict standards when new and that previously used wheels be recertified before every 500 mile race.

 

Unfortunately the same rigorous wheel inspection procedures are not typical for many driving enthusiasts who use their vehicles on the track. Maybe it's because wheels are so trouble free that they are often overlooked! But if let go for too long, wheels that are subjected to high stress track conditions can fail.

 

When it comes to wheel fatigue it is important to remember that it is caused by a combination of the frequency and magnitude of the stresses it encounters. While small stresses can be accommodated for thousands of cycles...large stresses accelerate the wheel's fatigue factor and the number of fatigue-free cycles is significantly reduced. So what is it about track use that reduces the life expectancy of wheels? Lets explore some of the important factors:

 

All wheels flex as they are driven through a corner. In normal street driving the amount of flex is minimal. However since today's DOT legal competition tires almost match the performance of yesterday's racing tires, every corner that is taken at the limit on the track causes significantly more flex. It's the combination of the extra tire grip and the resulting extra flex that fatigues wheels faster when used on the track. And don't forget that spins, running over the track edge curbs and unintentional trips through the run off areas add their own unique extra stresses.

 

During track use, wheels will often reach temperatures never encountered on the street as they help dissipate the brake heat. This constant cycling between the ambient temperature and the extremes encountered on the track can increase the fatigue rate of alloy wheels.

 

In normal street driving wheels are typically removed from the vehicle only when the tires are being rotated (typically every 5,000 miles) or replaced (typically every 25,000 to 40,000 miles). But when used on the track wheels are typically removed from the vehicle at the start and finish of each day, as well as, anytime the vehicle's brakes or suspension are being serviced. Additionally DOT legal competition tires wear out and are replaced much more frequently than normal street tires. These extra tire mountings and vehicle installations can increase wheel fatigue as they wear out the wheel's lug seats and the vehicle's lug nuts/studs or lug bolts/hubs.

 

So what should track drivers do to take better care of their wheels and minimize the possibility of wheel failure?

 

Before going on the track

 

Make certain that the wheel's installation hardware is correct for the vehicle and in good condition. Since almost all of today's cars are designed with hub centric wheels which transfer the vehicle's load from the center of the wheel to the car's hub (and allow the lug nuts/bolts to just hold the wheel against the hub), it is important that track wheels continue to be hub centric to help distribute the forces encountered on the track. If an aftermarket wheel requires special centering rings to properly fit it to the hub, be sure they are installed and installed correctly.

 

When any non-Original Equipment wheel or lug nut/bolt is used on the vehicle it is important that there is sufficient thread engagement between the lug nuts/bolts and the vehicle's hub. Its acceptable to increase the thread engagement by installing longer wheel studs in the hubs after verifying that the lug nuts don't bottom out on the studs. However if the vehicle uses lug bolts they must maintain as close to the original amount of thread engagement as possible. Longer lug bolts may cause interference with the parking brake or other components inside the hub.

 

Always torque the wheel's lug nuts/bolts to the hub using a "star" pattern until the vehicle's correct torque value is reached.

 

NOTE: If wheel spacers which are thicker than the height of the hub are used, they also need to be wheel and hub centric to help distribute forces.

 

After coming off of the track

 

At the end of every track day the wheels should be allowed to cool, cleaned front and back, and inspected for minute cracks, impact damage and runout. At the first sign of a crack appearing (regardless of size or location) or an indication the wheel has been bent it should be removed from service and replaced with a good wheel.

 

Every time new tires are mounted, each wheel should be inspected to verify that it is round and true. If it is found to be bent, it should be removed from service and replaced with a good wheel.

 

If the wheel has been used for an extended period of time you may want to have a local machine shop professionally crack test it in the off season before considering subjecting it to another year of track use.

 

Wheels are a critical component to your car. However because they tend to fatigue slowly, periodic inspection will usually reveal the signs of aging and use (such as minute cracks in the wheels spokes or near the bolt holes) long before they can become a serious problem. However if overlooked, once a crack has formed it will concentrate the stresses in the weak area and allow the crack to spread until the wheel fails.

 

It is important to note that track use and/or participation in racing voids the manufacturers' warranties of all street wheels.
