Toyos are a much better tire for driving on the street. My bro had toyos in 35x12.5R20 and they were great tires. Not loud at all and were a very nice tire. My opinion though the Mud Grapplers look much better than the Toyo. I think when your spending that much on tires you should choose what tread pattern you like most, or loud vs quiet. Just weigh the options. Loud vs quiet, tread pattern, etc, etc.

 

With the Mud Grappler you will never be let down when Off Road, in Mud, or snow. But when it comes to highway driving they can be a little loud and are pretty heavy (But they are Mud Tires). They look nice on my Chevy Silverado and if you have the money then I would definitely recommend them. I've never had the Toyo's but I heard they are decent on and off road. So either tire you pick will do the job.
