The Rim Guard HD+ utilizes the reinforced internal structure to boost the durability. The strengthened construction keeps the optimal tire shape under the load and driving pressure. As the tire does not deform under the load and driving pressure, enabling the tire to securely carry and withstand heavy loads with ease. This significantly improves the overall load capacity. The reinforced sidewall structure and the rim guard prevent damage. They protect the rims and the sidewall from accidental damage during their performance.
