Freeze Crack Advisory: This advisory addresses proper storage and use of Hoosier tires in cold conditions. Hoosier Tires, especially asphalt and hard compound 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 Hoosier 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 hrs 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. If below freezing temperatures are expected, please consider shipping tires once more favorable conditions exist.
Do not use tires that have evidence of Freeze Crack Damage.


Service Life For Race Tires:  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. Hoosier Racing Tire strongly recommends that new (sticker) tires should be put in service within 2 years of date of purchase. Used (scuffed) tires have a shorter service life than new (sticker) tires. Poor storage and infrequent use accelerate the aging process.


ROTATIONAL GUIDELINES FOR TIRES WITH DIRECTIONAL ARROWS
All Hoosier tires having directional arrows must be mounted so that the tire travels in the direction of the arrow. Hoosier tires having directional arrows will have them on both sidewalls.  Directional arrows may not be on a tire that can have both a left and/or right side application. All Hoosier tires not having directional arrows should be mounted as detailed below.
ROTATIONAL GUIDELINES FOR TIRES WITHOUT DIRECTIONAL ARROWS
Every Hoosier race tire has a four character serial code embossed into ONE sidewall of the tire. All Hoosier DOT tires will also have two additional codes as required by the Department of Transportation. (Example: J7AB 4AX8 3710)
CIRCLE TRACK RACING TIRES: (Includes both dirt and asphalt tires)
Hoosier tires must be mounted with the serial code located toward the infield.
ROAD RACING TIRES: (Includes catalog numbers beginning with 43, 44, 45, 46)
In most cases, Hoosier tires used in Road Race applications should be mounted with the serial code toward the center of the vehicle.  Once a tire has been run in the proper orientation it is acceptable to remount the tire in the opposite direction to even out the wear.
DRAG RACING TIRES, INCLUDING DOT DRAG TIRES: (Includes catalog numbers beginning with 17, 18)
Hoosier drag tires can be mounted to rotate in either direction. Hoosier drag tires can also be flipped or reversed to provide even wear.


Special Tire Mounting Instructions: 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. Always inspect tire for kinked beads or other possible damage that may have occurred in shipping or storage. Clean rim and lubricate beads with rubber lubricant. Always lock rim on mounting machine or place in safety cage. 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.


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 Hoosier 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.


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.


NOT FOR HIGHWAY USE: All Hoosier Racing Tires including DOT labeled Hoosier Racing Tires are designed for racing purposes only on specified racing surfaces and are not to be operated on public roadways. DOT labeled Hoosier Racing Tires meet Department Of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire including DOT tires on public roads. The prohibited use of Hoosier 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.  Exception - "PRO STREET"


Application/Misuse: All Hoosier Racing Tire products are designed for a specific purpose. Consult with Hoosier Racing Tire Corp. for specific fitment and application. Utilizing Hoosier Tires in any form outside of their intended use constitutes misuse of the product and can cause SERIOUS PERSONAL INJURY OR DEATH. Hoosier Racing Tire products are designed and manufactured for racing purposes only, within a closed course designed for organized competition. Not for recreational use. Hoosier Tires should never be used for Off Track Exhibition or for Land Speed Record Vehicles including Jet or Rocket Powered Cars.


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