Introducing PREMA's Smarttrio of Radial Repairs - the PR-109, the PR-110 and the PR115.The PR-109 is a small, reinforced radial repair designed for 1/8", 1/4" and 3/8" injuries in passenger tires.These tires experience low operating pressures and loads. This minimizes the size of the reinforcing ply required to repair these small injuries. In larger tires - light and medium truck - the operating pressures and loads are significantly higher than those of a passenger tire. This requires the PR-110's larger reinforcing ply to support the injured area of the tire.The reinforcing ply of the PR-110 is 30"/ larger than that of the PR-109. The PR-110 is designed to repair 1/8" injuries in medium trucks and 1/8" and 1/4" injuries in light trucks. In severe applications involving excessive loads and high heat an even larger reinforcing platform is recommended to support these higher stresses.The reinforcing ply of the PR-115 is 35% larger than that of the PR-110. It is recommended to use the PR-115 in place of the PR-110 in these severe applications. As explained in the advertisement, each of these repairs will fix a 1/8" injury. To determine which repair to use, the application should be considered in order to maximize success while minimizing the size and cost of the repair.
