Are RV tires the same as truck tires?

Can I put light truck tires on my trailer?
Yes, both special trailer (ST) and light truck (LT) tires can be used on a 5th wheel trailer

What does St stand for on a tire?

LT tires have thicker, reinforced sidewalls for heavy-duty use
and challenging driving conditions, they’re a great choice for off-road use.
What does ST and LT mean?

and feature heavier body plies, bigger beads, more tread depth and an overall heavy-duty design made for higher inflation pressures for heavier loads.
Are all LT tires 10 ply?
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-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.
