When it comes to light truck tires, you may come across service descriptions that include two load indices on the sidewall (such as LT 235/85R16 120/116S). It’s important to understand that the first load index pertains to single tire fitments, while the second load index is relevant to tires that are fitted in dual assemblies.

It’s worth noting that when LT tires are installed in dual assemblies, the load capacity is slightly reduced by 9% of the single load capacity. This reduction accounts for the effect of road crown, which can cause uneven tire wear and reduced performance. By taking this into consideration and ensuring that your tires are properly inflated and maintained, you can help maximize their lifespan and ensure optimal performance and safety on the road.
