Differences Between Car And Trailer Tires
Car tires and trailer tires look similar but have many differences. It is important to know these differences before using car tires on a trailer.
Trailer tires are made for carrying heavy loads and towing. Car tires are designed for driving and handling on roads.
Tire Construction
Trailer tires have stronger sidewalls than car tires. This helps them handle heavy loads without bending or breaking.
Car tires have flexible sidewalls to improve comfort and steering. This can cause damage if used on trailers.
Load Capacity
Trailer tires have a higher load rating than car tires. They can support more weight for towing safely.
Car tires are made to carry the weight of a vehicle and passengers, not heavy trailers.
