Many people use lift kits to make room for bigger tires, but you should always consult the owner's manual before doing this. In the manual, you will learn the load capacity and other helpful information. The size of your vehicle will determine what tires you can use. For example, your Dodge Ram won't accommodate the same size tires as a Chevy S-10. Additionally, if you can fit bigger tires, you need to think about how it will affect the suspension and balance.
