But that is a whole nother question...

I just picked up a 2012 Altitude for my Wife. She's looking for some rubber that is a bit more agressive and not so plain. (she's about one gene short of being a Mall Crawler) Any suggestions? I'd prefer to not lift it, simply as it will be a 99.9 percent road car. and occasionally maybe a lawn or flat field.

Any suggestions? Would like to keep the stock rims.

EDIT! BTW, I am uber ignorant to the whole numbers tire size, etc. for a guy who has three of them (no excuse! Everytime I buy one it's already a a great hight, tire size)... I am trying to educate myself but it's a slow process (not that bright!) thanks.
I have an altitude and a similar situation (99% onroad) so I'd like to see the answer on this one...

hey all

slight twist to the board

im going for 18inch rims 4.5 offset with a 2.5 inch lift...
wondering what size tire will stay under the flare (width) for legal purposes in australia.

because of the 18inch rim i am extremely limited for brand where i live and its Mickey Thompson MTZ all the way!

i have the choice of

305/60R18
325/60R18
275/70R18

want about 33inch high wich i think all of these are just worries about width as stated above.

thanks guys

With a 4.5" backspaced wheel, its going to be hard to keep the entire tire under the fender. The 275 would probably be the best choice given your situation. Here are the dimensions of the tires you posted:
305/60/18 - 32.4 x 12
325/60/18 - 33.3 x 12.8
275/70/18 - 33.2 x 10.8

Just for reference, here are my 285/75s (32.8 x 11.2) on 4.5" backspaced 8.5" wide wheels.

I've got the 2" front, 1" rear TF leveling kit. I think it looks great with the 285/75/16s I have, which spec out the same as those 285/70/17s. A lift will not void your warranty. The warranty just won't cover any of the parts that the lift replaces and will not cover anything that is deemed to have been broken due to the lift.

You will notice a slight decrease in performance. I have an '11 with 3.73 gears and I went down about 1.2 mpg with my setup. But my setup is not a light one. 86lbs per corner.

16s could possibly be cheaper, depending on which wheel/tire combo you go with. There aren't a whole lot of tire choices out there over 35 inches in the 16" rim diameter. If you never plan to go larger than 35s, then 16s can work just fine. All comes down to preference really.

The 2012 JKU Altitude addition has Rubicon shocks? Rubi Coils? Is that true.

I assumed it had the stock Sahara suspension, w just blacked out 18" rims, red sticker leather and blackout accents. Didn't think it has any performance/suspension changes from the Sahara.

No such thing as "rubi coils".

So after reading most of this thread, I'm thinking of going with:

BFGoodrich Mud Terrain T/A KM2 LT305/65R17E2 121Q W on Liquid Metal Gatlin 17X9 5-127 10MTB


on stock 2011 Rubi JKU, no lift yet. I cant find any BS data on these rims. I realize there will be some rubbing off road, until I can get it lifted. Any rubbing on steering or suspension components on road?

Opinions?

Those wheels would have roughly a 5.45" backspace. With a 305mm tire (12" wide), you might experience some rubbing when turning. I would personally look for a wheel with a 0 (or less) offset, which in the 9" width would put you at 5" or less of backspacing.

Ok, I've been reading all the forums but what I just want a few opinions on tire size. Seems like 285/70/17 is pretty common and a lot of folks have gone that route but I'd like to go with 305/70/17. Pros? Cons? I've thought of compromising and going with Nitto Trail Grapplers (295) but they just seem to be too heavy to be worth it. I'd like to keep the mpg close to what I get now. She is my DD but we also go boggin' in S GA and trail riding in N GA. We will be putting a leveling kit on her and she's already accessorized with Bushwacker flats. So, for those of you that went 285 - what kept you from going 305?

305 is wider which is a larger contact patch which is more rolling resistance. im getting 18 in town 24 on the highway with a 2 in lift 285s and 4.10 gears.

Like Lee said, the 305 would definitely lower your performance and gas mileage more than a 285 would. Not only because of the width, but because of the height as well. A 305/70/17 is 33.9x12, whereas a 285/70/17 is 32.8x11.2. Also, keep in mind that Lee has a 2012 which can deal with larger/heavier tires a bit better than your 2011. In my '11 3.73 auto, I get an average of 16.2 mpg with heavy 285/75/16s (86.2 lbs per corner).

That being said, if I had flats and a leveling kit, I'd go 305s (or 315s) without question.

Thanks you all for lots of great info!!

I have brand new Sport. Was thinking about a 4" spring lift and 35" tires, but then read about all the extra stuff I'd have to worry about, drive shafts and all. I think I'll just go with a 2.5"-3" lift and stick to 33's. Any comments on these: The wheel is a 17x9 with 4.5" BS.

Don't know much about the DC tires, but lots of people run the DC-2 wheels.

Rehearing

Again, thanks for a great thread.

I'm thinking more towards aesthetics rather than off-road functionality. 2.5 - 3 inch lift with 33 inch tires. The current gear is 3.21. Will I need to re-gear? If so to what? Again, my goal is to just have a mean looking ride to drive my rugby games rather than rock crawling. Thanks guys.

3.73 gearing should have extra torque for the 33's, and still keep decent mileage. Happy jeeping

Is there anywhere that has a walk through with pictures on how, how much, and what to cut? I'm new to the Wragler world and want 35" with a 2" spacer lift.....

275/70/r17 Disco'ed

I have a 2012 Wrangler Unlimited Rubicon.
Will a set of 275/70/r17 cause any rubbing on fenders or other parts when the swaybar is disconnected?
Would I need to adjust with smaller backspacing via spacers or afterarket rims?

Regards.

Thanks, I want to run 35"s but what I'm hearing from my contacts in Germany I can't have any rubber hanging out of the fenders and finding the right offset without trimming has proven hard.
