Question: how many ply are lt tires?
Answer: Very often LT tires will have an extra steel belt, a deeper tread and thicker rubber in the sidewall for more protection vs a p-metric tire. 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.
