What are the disadvantages of LT tires?
Because of their stiffer sidewall, LT tires don’t absorb bumps very well, causing more vibrations and road noise, particularly in lighter trucks and SUVs. That’s why we typically only recommend using LT tires on larger trucks, SUVs and vans, or for use in off-road conditions. LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-offs of the added material in LT tires are harsher ride, less fuel efficiency, and less responsive handling.Disadvantages of 10 ply tires increased fuel consumption: the weight and construction of heavy-duty vehicles, along with higher rolling resistance, result in a 5-10% decrease in fuel economy. Road noise: the stiffer construction, combined with deeper tread, generates additional cabin noise on well-paved surfaces.For hard-core towing and serious off-roading, 12-ply tires are better since they have the strength to carry the extra weight.
