Vehicles can steer, so their tires can roll along more easily.
Trailers, especially multi-axle ones, can't steer, so when going around a corner, the tires slide sideways.
Goodyear Endurance are great trailer tires (made in the USA). Many of the overseas tires that come stock on trailers, campers, etc. are junk.
I run the Endurance tires on our 5th wheel camper.
