FREEZE WARNING
  • Freeze Crack Advisory: This advisory addresses proper storage and use of NA tires in cold conditions. NA Tires may experience Rubber Cracking if the tires are transported, crushed, flexed or stressed when frozen.

  • The following guidelines are provided to avoid this problem:

  1. Always store NA Racing Tires indoors at temperatures above 32° F.       

  2. If tires have been subject to 32° F or less, allow them to warm to room temperature (about 70° F) for a minimum of 24 hours before tire is mounted, transported or flexed. 
  3. Always use spare tires not intended for future competition to store vehicles for prolonged periods of time or winter transport.
  4. Do not use tires that have evidence of Freeze Crack Damage.

 

SERVICE LIFE WARNING
  • Old tires can fail in use, causing loss of vehicle control and personal injury.

  • Environmental conditions like temperature extremes, exposure to sunlight, electric arc, solvents, automotive fluids, and atmospheric pollutants accelerate the aging process.

  • NA Tires strongly recommends that new tires should be put in service within 2 years of date of purchase.

  • Used tires have a shorter service life than new tires.

  • Poor storage and infrequent use accelerate the aging process.

 

DIRECTION OF ROTATION WARNING
  • If you need or want to change position of the tires after use, be sure to be mounted to keep rotating in the same direction that was before.

 

TIRE MOUNTING WARNING
  • Tire mounting should be done only by trained personnel using proper tools and procedures.

  • Failure to follow safe mounting procedures could cause faulty positioning of the tire and cause the assembly to burst with explosive force sufficient to cause SERIOUS PERSONAL INJURY OR DEATH:

  1. Always inspect tire for kinked beads or other possible damage that may have occurred in shipping or storage.

  2. Clean rim and lubricate beads with rubber lubricant.

  3. Always lock rim on mounting machine or place in safety cage.

  4. Use a clip on chuck, an in-line valve with a pressure gauge or adjustable regulator and remote inflation/deflation device.

  5. Have enough air hose to stay out of the trajectory.

 

RIM SIZE WARNING
  • Verify Correct Wheel and Bead Flange: All tires are designed to be used on wheels that are manufactured to Tire and Rim Association (T&RA) specifications and tolerances.

  • Some rims are non-standard or damaged and it is necessary to inspect the rim flange to assure proper fit.

  • Consult your specific rim manufacturer to determine if your rim can be used in this application.

  • Never attempt to install and inflate a tire of one bead diameter on a rim or wheel of a different bead diameter.

  • Use of NA Racing Tires on wheels with incorrect bead flanges or wheels that do not meet T&RA standards can cause the assembly to fail and burst with explosive force sufficient to cause SERIOUS PERSONAL INJURY OR DEATH. 

  • Use a certified wheel rim disk tape to confirm wheel rim flange size.

 

WARNING: BEAD/RIM SEATING
  • When seating beads never exceed maximum bead seating pressure as molded in tire sidewall.

  • Never exceed manufacturer's maximum inflation pressure. 

  • Always seat beads with wheel locked to mounting machine or placed in a safety cage. A damaged tire or wheel can fail during bead seating and burst with enough force sufficient to cause SERIOUS PERSONAL INJURY OR DEATH. 

  • Always use a clip on chuck, an in-line valve with a pressure gauge or adjustable regulator and remote inflation/deflation device.

  • Have enough air hose to stay out of the trajectory. Stand back. If the beads will not seat at the manufacturer's maximum bead seating pressure, STOP, deflate tire, return the tire to place of purchase.

 

WARNING: NOT FOR HIGHWAY USE
  • NOT FOR HIGHWAY USE: All NA Racing Tires are designed for racing purposes only on specified racing surfaces and are not to be operated on public roadways.

  • It is unsafe to operate any NA Racing Tire on public roads.

  • The prohibited use of NA Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and SERIOUS PERSONAL INJURY OR DEATH.

 

WARNING: MISUSE/MISAPPLICATION
  • Application/Misuse: All NA Tire products are designed for a specific purpose.

  • Consult with NA Tires USA for specific fitment and application.

  • Utilizing NA Tires in any form outside of their intended use constitutes misuse of the product and can cause SERIOUS PERSONAL INJURY OR DEATH.  

  • NA Tire products are designed and manufactured for racing purposes only, within a closed course designed for organized competition.

  • Not for recreational use.

  • NA Tires should never be used for Off Track Exhibition or for Land Speed Record Vehicles including Jet or Rocket Powered Cars.

 

WARNING: DO NOT ALTER TIRES

  • Chemical Treatment of Tires: NA Tires strictly forbids any chemical alteration of the tire carcass and/or tread compound such as tire "soaking" or use of tread "softener."

  • NA Tires strictly forbids the physical defacement (removal, altering or covering) of tire sidewall markings in any manner. Failure to comply with this warning could result in premature or catastrophic tire failure and may result in SERIOUS PERSONAL INJURY OR DEATH.
