LOUISVILLE, Ky.-Three technical reports documenting the integrity of retreaded truck tires are available at $12 each from the American Retreaders' Association. Undertread Heat Study (Item No. RR93-111) concerns the effects of undertread thickness on steel radial truck tires. It reports the results of road wheel testing on 18 steel radial retreads processed through a variety of retreading systems.
Burst Strength Study: New vs. Worn Truck Tires (Item No. RR93-112) covers the hydrostatic bursting of 13 worn but retreadable radials and three new tires, showing bursting pressure and what types of failures occurred.
Plunger Test Study (Item No. RR93-113) reports the results of subjecting a randomly selected 11R24.5, H-rated highway tread all-steel radial to the strength or plunger test required of new tires.
