could i fit 33\'s?? im looking for some cheep mud tires to toss on my rig since inm in serious need of better tires. i was thinking along the lines of mud king, dunlop radial mud rovers, and general grabber m/ts all in a 33/12.5/15 size. thing is is that i dont have any lift as of yet and with my current financial sititation i prolly wont have one for a while. what all would be involved in this. do i have to cut/trim the fenders or should it fit ok and only limit flex?
