TERMS AND CONDITIONS

Eligibility

This warranty applies to the original purchaser of an Atturo tire and is not transferable.

Eligible tires must be purchased new and must be used on the vehicle for which they were originally installed. Additionally, they must be of an equivalent or greater load index to that specified by the vehicle manufacturer. The load index is the numerical designation imprinted on the sidewall of the tire and corresponds to a specific load carrying capacity.  (Marks such as “Load Range E” or “10 ply rating” are NOT a load index as they do not correspond to any specific load carrying capacity.  These legacy markings may NOT be relied upon for accurate applications of load capacity.)  For warranty exclusions see “WHAT IS NOT COVERED”.


Standard Coverage

If an Atturo branded tire becomes unserviceable as a result of an eligible adjustable condition during the first 2/32" of tread wear, it will be replaced with an equivalent new Atturo tire, at no charge. When the tread is worn more than 2/32", if the product exhibits an eligible adjustable condition, it will be replaced on a pro-rated basis.  You must present proof of purchase and be the original owner when requesting a replacement for your tire.


You must pay for mounting, balancing, and any other additional charges, such as taxes or the acceptance of a higher priced replacement tire.


Any Atturo tire that does not deliver satisfactory service due to a confirmed balance, out of round or a ride complaint issue will be replaced without charge within the first 2/32nds of the tire’s tread life. After the first 2/32nds the tire is not warrantable for the aforementioned conditions.


Tread Life

Atturo makes no representation or claim of how many miles/kilometers a tire will last.  Tire life is ultimately a function of the application, use, care and driving habits of the owner.  When the tread becomes worn down to 2/32" (1.6mm) anywhere on the tire (shown by tread wear indicators molded into the tread grooves), the tire is worn out.


How to Obtain an Adjustment

Tire adjustments must be presented to the dealer which originally sold the tire. You must be able to provide proof of purchase and be the original owner when requesting a replacement for your tire. Proof of proper tire care such as rotation and alignment may be required.  See “Where to Go for Warranty Replacement”.


The original selling dealer will evaluate the tire and complete the initial warranty claim form.  The claim form is to be submitted back through the supplying distributor for return to Atturo.


What Is Not Covered

Adjustments will not be made for:

1. Tires that become unserviceable due to:

a. Conditions resulting from road hazards, such as impact damage, cuts, snags, or punctures.

b. Conditions such as, but not limited to, uneven, cupping, spotty, feathering tread wear resulting from improper installation, wheel misalignment, tire/wheel assembly imbalance, use of an improper rim, improper mounting or dismounting or improper fitment.

c. Conditions resulting from consumer damage, such as, but not limited to, improper tire and vehicle maintenance, misuse, abuse, accident, under inflation, overloading, over deflection, failure to follow recommended rotation practices, cut by vehicle, run flat or improper fitment.

d. Conditions resulting from suspension modifications (Ply Steer Residual Lateral Force)


2. Balance, out of round, lateral/radial pull or ride complaint issues after the first 2/32” of tread wear.


3. The installation of any tubes.


4. Tires used in any commercial, racing, or off-road applications.


5. Ozone or weather cracking on tires over (4) four years from date of manufacture or date of purchase. Proof of purchase is required. Without proof of purchase the manufacturer date will be used to determine eligibility.


6. Tires stored improperly.


7. Tires that are:

a. Worn unevenly and/or show a difference of 2/32” (1.6mm) between the grooves.

b. Installed on any vehicle other than the vehicle on which they were first installed.

c. Acquired as used (tires purchased used, equipped on a pre-owned vehicle, etc.).

d. Altered in any manner (additional siping, buffing, stud pin holes, re-grooving, truing, etc.).

e. Worn to 2/32” (1.6mm) or more than 60 months old (based on date of purchase) whichever comes first. Proof of purchase is required. Without proof of purchase, the manufacturer date will be used to determine eligibility.

f. Tires which have been punctured, whether or not they were repaired.  Failures subsequent to a repair are not covered.


7.  Tires installed on a vehicle which are lower than the original equipment specified load index by the vehicle manufacturer.


8.  Tires mounted on rims outside the published specifications of Atturo Tire.  Using wheels which are outside the specified range can have a detrimental effect on the load capacity, performance and overall life of the tire.


9.  Tires installed on dual real wheel vehicles which are not rated for dual applications.


10.  Damage during mounting or installation.


No Road Hazard Coverage

No part of this warranty shall be construed to provide coverage for road hazards and/or repairs. Atturo does not provide this coverage.


Where to Go for Warranty Replacement

Contact the Atturo dealer where the tire was originally purchased for initial inspection. If the dealer which originally sold the tire is no longer available, please visit our website and use the Dealer Locator to find a dealer in your area.  The original selling dealer will evaluate the tire and complete the initial warranty claim form.  The claim form is to be submitted back through the supplying distributor for return to Atturo.


IMPORTANT TIRE SAFETY AND FITMENT INFORMATION

CHOOSING THE RIGHT TIRE FOR YOUR VEHICLE – OWNER AND USERS OBLIGATION

Before choosing and installing any tires on a vehicle, vehicle owners and users must obtain and understand the tire safety and fitment information available (i) in the vehicle’s owner’s manual and related materials provided with the vehicle, and that can otherwise be obtained from the OE vehicle manufacturer; (ii)available within the industry and from the government; (iii) from the Rubber Manufacturers Association (www.rma.org), and (iv) the National Highway Traffic Safety Administration (www.nhtsa.gov).

The user must (i) review and discuss the tire safety and fitment information with their local installer/dealer, including the potential risks associated with not following the tire safety and fitment information; and (ii) have the local tire installer/dealer or a vehicle service professional inspect the vehicle (including any aftermarket modifications) to advise as to any potential risks associated with installing the tires desired by the user on the vehicle.


In all cases, it is the vehicle owner’s responsibility to ensure the correct tire is installed on their vehicle.  Atturo encourages owners to seek the guidance of competent dealers to select the correct type and size of tire for their vehicle and driving requirements.  Self-selection (such as an internet purchase) of a tire type and size is done at the owners assumed risk of misapplication. If, after doing so and considering this information, the user chooses to assume any potential risk and install a non-OE replacement tire on their vehicle, the fitment of the tire requires, at a minimum, all of the following special considerations are met.


SUSPENSION MODIFICATION

Due to inconsistencies in vehicle manufacturing and unknown production changes, when "upsizing" to a tire with a larger overall diameter, always consult a local tire dealer/installer (including for vehicles with unmodified OE suspensions).

Different suspension manufacturers’ requirements may vary. For lifted, lowered, leveled and/or modified vehicles, always check with the suspension manufacturer to find the suggested wheel and tire combination and additional safety information.  Installation of a suspension lift may require different alignment settings from the original specification to ensure proper handling and tire wear.  

Installing tires with a larger outside diameter than the OE tires (or modifying the vehicle's suspension) may create a higher center of gravity from the vehicle being fitted. This can alter the vehicle's braking, handling and response characteristics.  The combination of these modifications can cause Ply Steer Residual Lateral Force, which is a constant pull to one side regardless of the positioning of tires on the vehicle.  This is not an indication of a defective tire.  (Please see the standard procedure for determining which tire is causing a radial pull)


DO NOT OVERLOAD – DRIVING ON ANY OVERLOADED TIRE IS DANGEROUS

The maximum load rating of your tires is marked on the tire sidewall. Do not exceed these load ratings. Tires which are loaded beyond their maximum allowable loads for the particular application will build up excessive heat that may result in sudden tire destruction. Reference the maximum load carrying capacity and load index of the vehicle's specified OE tire as listed on the vehicle’s tire placard and/or certification label. A tire must be selected with a maximum load carrying capacity and load index that is equal to or greater than the vehicle's specified OE tire maximum load carrying capacity and load index. Do not exceed the gross axle weight ratings for any axle on your vehicle.  (Marks such as “Load Range E” or “10 ply rating” are NOT a load index as they do not correspond to any specific load carrying capacity.  These legacy markings may NOT be relied up on for accurate applications of load capacity.)


SPEED RATED TIRES

Reference the speed rating of the vehicle's specified OE tire as listed on the vehicle’s tire placard and/or certification label. A tire must be selected with a speed rating that is equal to or greater than the speed rating of the vehicles specified OE tire.  It is not advised to mix different speed rated tires on the same vehicle.  Installing a lower speed rated tire than the OE specification may result in reduced vehicle performance and tire life.  


SELECTING A PROPER INFLATION PRESSURE IS CRITICAL TO TIRE PERFORMANCE AND SAFETY

When an original equipment tire is replaced with a tire of a different size, or different load capacity, the proper tire pressure must be determined and applied.  Any under inflated tire builds up excessive heat that may result in sudden tire destruction.

If the replacement tire has a maximum inflation pressure (as listed on the tire sidewall) different than the maximum inflation pressure on the OE tire, then the proper inflation pressure for the replacement tire may be different than the OE recommended level. The user may need to make adjustments to inflation pressure, including to prevent over inflation and/or over deflection of the tires and/or to provide an adequate load carrying capacity as compared to the OE tire.


As a general guideline, the below formula may be used to calculate the correct air pressure for standard use.


(Required Load / Tire Maximum Load) X Maximum PSI = Required PSI

   

The Required Load is calculated by taking 50% of the Gross Axle Weight Rating (GAWR) of the vehicle and adding 10%.  The addition of the 10% factor is a generally accepted principle of the industry and recommended by the DOT to take into account the additional load by force applied to a tire while under acceleration, braking, turning, and other actual use which stress the tire beyond the simple static load of the vehicle.  The calculation should be completed for each axle if they have different GAWR.


For example, in the case of a vehicle with 5000 LBS GAWR, using a tire with a maximum load capacity of 3190 LBS at 65 PSI, the formula would work as below:

5000 / 2 = 2500

2500 X 1.10 = 2,750 Required Load.


(2750 / 3190) X 65 = 56 Required PSI
