#32 of 226 Jeep Wrangler from 15 " to 17" Wheels-posible
Mar 18, 2007 (11:19 am)
I have a 2004 Wrangler SE 4WD without lift. It has factory 15" x 7" Styled Steel wheels with P215/75R15 Goodyear Wrangler.
Can I change to 17" by 7 1/2" Chrome Wheels without lift?
The tires I would like on the wheels would be either
1)Goodyear Fortera P245/65R17 or
2)Goodyear Eagle P255/60R17.
Will these wheels and tires work? and if so what is the best option or is there another option? (note: FYI, the wheels I'm getting free from my brother so I can't change wheels).

Assuming that the mounting holes and backspacing are the same as your present wheels there shouldn't be a problem. The tires you want aren't an extreme size and it doesn't matter if the hole in the middle is 15" or 17".
Eagles are a performance on-road tire, but if you stay on-road that's not a problem.

I'm a newbie to four wheeling and I need an answer to a question about tires. I have a 2006 Jeep Rubicon Unlimited that came from the factory with LT245/75R16 tires 30x9.5
I want to beef it up a little and put bigger tires on it. I was thinking going maybe 32's or 33's do I need to lift my Jeep for tires that big? I have Dana 44 heavy-duty front and rear axles if that matters. Any help would be greatly appreciated.

For 33's you'll need a 3" lift. A 2" suspension plus a 1" body is the usual way to go. 31"x10.5" is the max otherwise.

Thanks for the response. Do you know of any good web sites that might have some decent literature on lift kits?

Your best bet is to check out the various jeep forums out there.
Many love the OME (Mac24, tsjay, and I all have it) for its onroad ride (many say better than stock, I agree), and it's nice flexing capabilities offroad. It is pricier, but with lifts, you often get what you pay for.
Rubicon Express is another good one. I've also heard many good comments about Rusty's Offroad (located here in AL) having a nice ride and flex.
Keep in mind, if you go bigger than 3-4", you have to worry about other issues (drivelines, steering geometry, etc), so a 2-3" suspension lift with a 1" body lift will be a GREAT way to get that Rubicon up in a decent manner.

Jeepgurl, great timing. I was browsing the Jeep forums just for the question you had!
I have a Jeep Unlimited and also want to "beef" it up. I was also considering 33" tires.
A few more questions:
- Why a 2" suspension lift and 1" body? Why not just a 3" suspension?
- Any issues with driving at higher speeds (60-70mph) with a lift like this?
- If I went 33 I was considering the BFG All-Terrain. Any opinions?
- AND.. last but not least, for those of you who had your Jeep lifted, what was the overall cost? I'm in the Chicago area...

That's why we're here. Ask anything else you need to know!

Karl, as mac and I mentioned previously, there are factors to consider with going to a larger suspension lift.
- You may have your axles shift to one side more
- You may have to change your pitman arm, which alters the steering geometry and can lead to more uncontrollable steering (death wobble)
- If you go too big on the suspension lift, the control arms will be too short. The stock control arms are good to about 3" or 4", but any larger, and you REALLY need to go long arm or run the risk of an unstable/uncomfortable Jeep.
- Center of gravity
A 2.5" lift or so will cost a bit less (normally) and minimally impact axle centering and steering geometries. Also, if you think of the control arms as the radius of a circle, with a smaller lift, the axles and wheels rotate down and 'in' towards each other. A higher lift will bring them in a bit more, leading to a possibly harsher ride. A SWB TJ is bumpy enough.
Larger lifts will impact them more.
While a 2.5" lift will fit 32's no problem, 33's will really fit nicely with that 1" Body lift, and 33's are about the ideal size for a daily driven Unlimited, IMO.
That body lift also keep the frame lower, giving a better center of gravity (lower). That will help stability in turns. A body lift also opens the door for other mods, such as a tummy tuck to raise the transmission.
As for the cost of the lift, I did the work all myself, but I bought the DPGOffroad Basic kit, and have since pieced together the body lift, motor lift, adjustable trackbars front and rear (to recenter the axles), and the quick disconnects for the sway bar for offroad articulation. That would be the ultimate kit on Dirk's www.dpgoffroad.com site.
If you guys end up using him, just let him know Paul in Alabama referred ya. I don't get any discounts from him, but I like to let him know I'm keeping my word of letting people know about his EXCELLENT service and products. My entire suspension and lift is from him, as are all my headlights and driving lights (IPF).
Even with my TJ being a 4cylinder, I have NO problems at highway speeds (up to about 78 or so).
33" BFG AT's would be great for Chicago, but I'm not sure how well they handle winter snow/ice. I hear the Mud Terrains actually handle it better and I know a LOT of people who use the BFG MT's on their TJ. While they may be a bit noisier, I kinda like the road noise my Jeep makes. I have TrXuS Mud Terrains, but ran the 30" variety of the BFG AT's prior to that.
And before you ask, the quick disconnects allow better articulation offroad and give better flex, like this:
