VEVOR Boat Trailer Dolly, 420lbs Load Capacity, Carbon Steel Trailer Mover with 96''-116'' Adjustable Length, 16'' Pneumatic Tires & Nonslip Support Bracket, for Moving Kayak Motorboat Fishing Boat

Good evening I would like to know if the wheels are equipped with bearings or not. I can attach this trailer to the back of a car? Can ship to Northern Ireland Belfast? Thank you
