I know this has prolly been posted a million times!! What are the differences in the gators and the mud bugs??? I can get the gators for like alittle over $50 cheaper and I was wondering the differences?? Is the tread deeper on the gators do they weigh more or less if so how much?? Thanx abunch guys and by the way I am lookin at the 28x10 for the front and 28x12 for the rear!
