KENDA/LOADSTAR Limited Warranty – Trailer Tires

 

This policy applies to KENDA/LOADSTAR trailer tires sold and used within the USA and Canada only.

 

ELIGIBILITY

You are eligible for the benefits of this warranty (the “Limited Warranty”) only if you are the original owner and consumer of new KENDA/LOADSTAR trailer tires, such tires bear the original Department of Transportation (DOT) – prescribed tire identification numbers, and such tires are on the trailer upon which they were originally installed according to the trailer manufacturer’s or KENDAS’ recommendations.

 

WHAT IS WARRANTED AND FOR HOW LONG

 

Subject to the limitations contained in this Limited Warranty, your new KENDA/LOADSTAR tires are warranted under this Limited Warranty against failures due to defective materials and workmanship for a period of four (4) years from the date of tire manufacture or two (2) years from date of purchase, whichever occurs first. Tire manufacture date is determined by the Department of Transportation (DOT) – prescribed tire identification numbers.

(A)    Eligibility: A tire is eligible for warranty coverage under this Limited Warranty only if the tire is presented by the original owner and consumer within four (4) years of the tire manufacture date or two (2) years from date of purchase, whichever occurs first, the tire has a minimum of 2/32nd inch of tire tread depth remaining, and all procedures in this Limited Warranty are followed.

(B)     Free Replacement: Subject to the limitations contained in this Limited Warranty, if a KENDA/LOADSTAR tire fails due to defective materials or workmanship during the first 10% of treadwear, the tire will be replaced with a new comparable KENDA/LOADSTAR tire without charge.

(C)     Treadwear Prorated Discount: A defective tire that does not qualify for free replacement under (B) above, but that is otherwise eligible for warranty coverage under this Limited Warranty, will entitle you to a discount on the purchase of a new comparable KENDA/LOADSTAR tire.  The amount of the discount will be calculated based upon the percentage of tread that remains on the defective tire. For example, if 60% of the original tread remains on the defective tire, you will be entitled to a 60% discount off of the retail price of a new comparable KENDA/LOADSTAR tire. You are responsible for all labor costs for mounting and balancing and for all applicable taxes.

 

DEFINITION OF COMPARABLE TIRE

 

A “comparable” new KENDA/LOADSTAR tire may either be the same line of tire or, if the defective tire is out of production or unavailable, a tire of the same basic or equal construction and quality with different sidewall or treadwear configuration. If a higher priced tire is accepted as replacement, you will be responsible for the difference in price.

 

COMPUTING TREADWEAR

 

Treadwear is computed as a percentage of the original usable tread. The original usable tread does not include the last 2/32nd inch of tread depth. KENDA USA shall make all determinations regarding treadwear and eligibility for warranty coverage under this Limited Warranty in its sole discretion.

 

WHAT IS NOT COVERED BY THE WARRANTY

 

This Limited Warranty does not apply to:

(A)    Damage, failure, or irregular or premature treadwear caused by, resulting from, or arising out of fire, accident, chemical corrosion, malicious mischief, vandalism, or road hazards. Example of road hazards include, without limitation, nails, glass, rocks, curbs, and other foreign objects and natural and manmade obstructions or obstacles such as excavations, construction, potholes, and chuckholes. Damages caused by road hazards can include, without limitation, cuts, snags, punctures, scuffs, carcass bruises, and impact breaks.

(B)     Damage, failure, or irregular or premature treadwear caused by, resulting from, or arising out of improper operation or maintenance such as, without limitation, misapplication, neglect, misuse, running flat, overloading, under-or-over inflation, excessive speed, improper installation, improper wheel alignment, improper mounting or dismounting, use of puncture sealants, tire plugs, or fillers, noncompliance with safety, usage, or maintenance instructions or parameters, or any alteration to the tire such as, without limitation, grooving bead or sidewall decorative material or the addition of a white inlay (whitewall) to any tire.

(C)     Weather cracking

(D)     Loss of time, inconvenience, loss of use of the trailer, costs of towing or transportation, and/or incidental or consequential damages of any type or nature. Vehicle or trailer damage is not covered.

TRAILER SAFETY INDUSTRY COALITION

“Committed to Trailer Safety”

SAFETY TIP #2

Trailers: A Word About Safety

The Trailer Safety Industry Coalition (TSIC) is a coalition of trailer and component manufacturers formed to identify and address issues that can improve the safety of towable equipment. The TSIC is developing a series of safety tips to assist consumers in maintaining their towable equipment.

 

Trailer Tire Information

Trailer tires may be worn out even though they still have plenty of tread left. This is because trailer tires have to carry a lot of weight all the time, even when not in use. It is actually better for the tire to be rolling down the road than to be idle. During use, the tire releases lubricants that are beneficial to tire life. Using the trailer tires often also helps prevent flat spots from developing.

 

The main cause of tire failure is improper inflation. Always check the cold tire inflation pressures before each trip and at least once a week during the trip for proper inflation levels. “Cold” means that the tires are at the same temperature as the surrounding air, such as when the vehicle has been parked overnight. Wheel and tire manufacturers recommend adjusting the air pressure to the trailer manufacturer’s recommended cold inflation pressure, in pounds per square inch (PSI) stated on the vehicle’s Federal Certification Label or Tire Placard when the trailer is loaded. Never load a trailer to a weight greater than its gross vehicle weight rating (GVWR). If the tires are inflated to less than the recommended inflation level or the GVWR of the trailer is exceeded, the ability of the tires to safely carry the load could be dramatically affected. If the tires are inflated to more than the recommended inflation level, handling characteristics of the tow vehicle/trailer combination could be affected. Refer to the owner’s manual or talk to your dealer or vehicle manufacturer if you have any questions regarding proper inflation practices.

 

Tires can lose air over a period of time. In fact, tires can lose 1 to 3 PSI per month. This is because molecules of air, under pressure, migrate through the rubber from the inside to the outside. A drop in tire pressure could cause the tire to become overloaded, leading to excessive heat build up. If a trailer tire is under-inflated, even for a short period of time, the tire could suffer internal damage.

 

High speed towing in hot conditions degrades trailer tires significantly. As heat builds up during driving, the tire’s internal structure starts to break down, compromising the strength of the tire. It is recommended to drive at moderate speeds.

 

Statistics indicate the average life of a trailer tire is about five years under normal use and maintenance conditions. After three years, replacing the trailer tires with new ones should be considered, even if the tires have adequate tread depth. Some experts claim that after five years, trailer tires have degraded to the point that they are considered worn out and should be replaced, even if they have had minimal or no use. This is such a general statement that it may not apply in all cases. It is best to have your tires inspected by a tire supplier to determine if your tires need to be replaced.

 

If you are storing your trailer for an extended period, make sure the tires are fully inflated to the maximum rated pressure and that you store them in a cool, dry place, such as a garage. Use tire covers to protect the trailer tires from the harsh effects of the sun. It is also a good idea to place a barrier between the trailer tires and a concrete or asphalt surface it is parked on. A thick garbage bag, a piece of carpet or a piece of plywood will do the job. This will prevent possible tire damage from chemicals in the parking surface.

Tire Wear Guide

 

  • Tire inflation pressure is one of the most important factors in tire life. Tires should be inflated to the pressure recommended by the manufacturer for the load. Please check the side wall of you tire for the correct PSI ratings. Pressure should always be checked cold before operation. Check inflation pressure weekly during use to insure maximum tire life and monitor tread wear.

    If you have any questions, about your tires, performance, appearance, etc, please contact the tire manufacturer. You can find the manufacturer's name on the sidewall of the tire.

 

Tire Wear Guide
The following Tire Wear Guide will help you identify the causes and solutions of most common tire wear patterns.

 

Wear Pattern

Cause

Solution

Center Wear

Over Inflation

Adjust pressure to particular load per tire catalog

 

Edge Wear

Under Inflation

Adjust pressure to particular load per tire catalog

Side Wear

Loss of camber or overloading

Make sure load doesn't exceed axle rating. Correction is 3/4 - 1 degree positive camber (top of wheel rim 3/16" further out than bottom.

 

Toe Wear

Incorrect toe-in

Correct toe-in is 0 - 1/2 degree.

 

Cupping

Out-of-balance

Check bearing adjustment and balance tires.

 

Flat Spots

Wheel lockup & tire skidding

Avoid sudden stops when possible and adjust brakes.


Tire wear should be checked frequently because once a wear pattern becomes firmly established it is difficult to stop, even if the underlying cause is corrected.

NOTE: If your trailer's tires show any unusual signs of wear, contact the tire manufacturer or a tire dealer for recommended corrective procedure.

  • For tire warranty issues, please contact the tire manufacturer.
