More About UMP Dirt Modified Tires

Hoosier Racing Tire Corp. is the largest race tire manufacturer in the world and all Hoosier race tires are still proudly "Made in the USA." The company continues to be privately owned and operated by the Newton family, co-founder Joyce Newton along with many of the Newton family members remain actively involved in the day-to-day operations of Hoosier. Hoosier has grown to be one of the largest employers in Plymouth, Indiana producing over 1000 different types of race tires. The company has its own 300-mph test wheel; a technology center; state-of-the-art, fully-integrated production facilities recently adding a high-tech mixing plant, with enough capacity to produce not only for Hoosier Racing Tire, but to have the ability to produce rubber for additional entities; not to mention a model sales and distribution network in Lakeville, Indiana which others seek to emulate.

The pride that exists among those associated with Hoosier "family" continues to be the focal point of the success the company has enjoyed over the years. Joyce and the Newton family, as well as others involved in the racing industry, marvel at the success and growth of the original business the Newtons started almost 60 years ago. At Hoosier, we know that if you build a company with talented, hardworking people who care, and produce a product that performs at an affordable price, you will satisfy the needs of your customers and both you and they will be winners. This philosophy has been, and will continue to be, the secret behind Hoosier's success in building "Tires Designed for Champions."

WARNING! TIRE MOUNTING IS DANGEROUS

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.

WARNING! VERIFY RIM SIZE

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.

WARNING! BEAD / RIM SEATING

When seating beads never exceed maximum bead seating pressure as molded in tire sidewall. Never exceed manufacturers 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 manufactureres maximum bead seating pressure, STOP, deflate tire, return the tire to the place of purchase.

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.

Application/Misuse: All Hoosier Racing Tire products are designed for a specific purpose. Consult with Hoosier Racing Tire Corp. for specific fitment and application.
