Built with heavy-duty carbon steel, this 4-piece car wheel dolly set delivers exceptional strength and durability, supporting a total load capacity of 6,000 lbs with 1,500 lbs per dolly to reliably handle vehicle moving and daily automotive maintenance. Featuring a raised anti-slip patterned steel plate and grooved center design, these dollies maximize tire friction for a tight, secure fit, effectively preventing slipping and shifting during use for enhanced overall stability. Equipped with smooth-rolling 3-inch swivel casters and reliable locking wheels with foot brakes, the dolly enables flexible directional movement and instant stable locking, supporting safe, effortless one-person operation. Boasting wide compatibility, it fits tire widths up to 12 inches and works perfectly for family cars, SUVs, and ATVs (not suitable for boats). Simple to set up, just jack up the tires, place the dollies in position and lock the casters. Designed with a practical hanging handle for space-saving storage in garages or vehicle trunks, this versatile dolly set is a must-have tool for tire replacement, vehicle repositioning, and general garage repairs.
