Stay away from the Nitto Terra Grappler, they are trash. I had 285s on 17 inch rims a while back and they did nothing but give me problems. If I wasn't spinning in wet grass I was bouncing in sand. I haven't heard anything good about the Mud Grapplers except how they look. I would recommend the Kumho Road Venture MT KL71(cheap for the tire) and def those Interco M16s. Also a buddy of mine had some Firestone Destination MT and they were pretty well rounded tires, did awesome in the mud. Have nothing bad to say about my Mickey Thompsons except the price, they do awesome in the mud and sand, don't let the picture of that tire discourage you, they look WAY more aggressive in person.
i like the nitto line of grapplers but they are a bit pricey, and ive found falken's new wildpeak a/t tires that are leaning me in thier direction at the moment. goodyear is totaly out of the question - the wrangler hp's suck so bad in anything but dry conditions, and i dont think the tires hold up well at all IMO. all in all im still looking cuz im not getting new tread till later in the year, closer to winter time and snowy conditions.
I've got Mickey Thompson Baja ATZ. They are 35x12.5x20(stock 20s) I honestly won't get these tires again. They are too expensive for me, they run about $400 a tire and they are only all terrains. What kind of tires are you looking for? Any 35" for a 20 inch rim will fit our rims no problem. So don't let the sites confuse you. As long as it is a 12.5 and not a 13.5 you'll be ok with no problem.
i got procomp's 2" level shackles, i need to get new shocks before i install them, and want to run 35's on the stocks. whats the size of the tire your running. i've looked online at rims and tires and allot of places dont have 35's on the 20x9 rim and others do. the whole tire and rim sizing gets confusing from site to site. any info you got for me would be appreciated. thanks
