mudzillas are pretty good. heavier then the laws though. you will need at least 1" spacers if you stay with your stock rims like i did. i put 1.5" spacers in the rear just so the front and back tires stuck out the same amount.
If you go with either tire make sure you have some spare axles and front diff parts laying aroud! They both can be hard on parts. The Outlaw is a better mud tire in most cases. If there is a hard bottom the Mudzilla's will hold their own.
