A radial is a type of vehicle tire that uses belts under the tread area to reinforce its strength and provide better fuel economy.
They are also lighter than other types of tires because they have fewer layers inside — which saves you money by using less material.
Finally, radials are more expensive because they require higher-quality materials for durability and longevity purposes. Their long life expectancy makes them great if you plan on keeping your recreational vehicle for a long time.
