Hey guys, so I'm getting ready to order my lift, and figuring out everything I need (read: budgeting my money).

Facts:
-I have a 2007 6-speed with 53,xxx miles
-Right now I have NO lift.
-I have 235/70-15 BFGoodrich Radial Long Trail T/A
-Cragar D Window 15x7 w/ 4.0 inches of Backspace
-I'm getting roughly about 18 inches from center of wheel to the fender front and rear (about 12.5 inches at pinch weld, also Jeep was not level, not sure if that makes a difference).
-I am going to pound the pinch weld (preferably before I buy the tires.)
-I plan on buying the Frankenlift Premium II

I think that is everything. (Let me know if you need more info)

I'm looking at tires, reading many posts, including the 6 pages of Tom's review, I'm pretty sure I am going to go with the Goodyear Wrangler DuraTracs.

I plan on buying the DuraTracs in a 31x10.5R 15.

So, I guess what my question(s) is (are); ..lol..
(specifically with the tire size, not brand [and I know different brands have different actual sizes even though the "official" tire size is the same])
-Will it even be possible to run these with no lift? (I'm assuming not, especially without major front bumper modification)
-Will it even be possible to run these after the lift?
-How will it affect how the Jeep drives? (I know 30.5 should be ok without having to re-gear).
-And, pretty much any info/suggestions you (smarter) people can think of.

Just as a small comparison, according to TireRack,
The Goodyear Wrangler DuraTracs;
-in a 31X10.5R15 are 10.5" wide and 30.5" in diameter
-in a 245/75R16 are 9.8" wide and 30.5" in diameter
-in a 265/75R16 are 10.5" wide and 31.7" in diameter (tommudds)

Once again, thanks in advance for all the very knowledgeable responses I know I'm going to receive :lol:

-Dean

Not without a lift. With a lift, yes.

Smaller size, but to give you an idea:

i have 31 x 10.5's on soft 8's with 4" bs as my second set of meats. I have a 2" revtek spacer lift, with 130k, so i'm guessing i don't really have that much lift. I had to do lots of trimming to make it drivable. as things are now, i only have some rubbing while turning (most of the time it only when backing up). the part that blows is that it is rubbing on the beat down, ground down pinch weld. :shock: and in all actuality, i probably need to remove the plastic liner around the pinch weld as well b/c i have scuff marks from the tires rubbing. all of this is even with 5 conduit nuts for a little extra breathing room. i hope to install the frankie 2 like you are planning on doing, i think that will give me the little more room i need.

the extra weight of the tires and wheels didn't have as much of a negative effect as I was expecting :mrgreen: i must say though that the look of the new wheels and tires more than makes up for the little bit of rubbing i have left!
