that size will work with no lift.

what size are you talking about?? the 235's are stock so they will fit no problem and the 255/75/15 is about 30" tall and 10" wide theyre might be some rubbing issue with the sway bar, but thats not a big deal and the 30x9.50's are the biggest tire you can fit on a non lifted 4x4 now since the OP has cranked tb's he'll be able to fit any of these sizes with little to no issue.

What do you guys think of the Firestone Destination MT tire? It comes in the size I'm looking for here.

i know the Fireston Destination A/T is a very good tire so i would imagine the M/T is very good as well. cheack out tirerack.com they have reviews on each tire you can read over.

C'mon Heffty... You do realize that you will probably be looking into body lifts a few weeks down the road from now right? After that is the 6" lifts and 33"s... it's a vicious cycle... lol

I have already thought about that possibility. I don't think I will be going that route though. The last time I took my Blazer off roading I did pretty well until I hit a mud bog. Two other full size pick ups with much larger tires and lifts wouldn't even attempt the bog on that day, so what's another 2 inches really going to do for me? I want the tires because they are practical and they look great. I cranked the torsion bars because it cost me nothing...and hopefully my suspension will hold together. I rarely drive the Blazer because I have a work truck. Overall I'm a cheap bastard. I'll probably wait until fall anyway when there are better tire sales. I'm a cheap dude is all it comes down to and a lift is not cheap.
