and I agree, thats why I suggested to the OP to run 31s with the smaller lift he was thinking. 2-3 inches with 31s is an awesome setup offroad. I ran it myself for a while.

|TJWenatchee||True, lots of disagreement about height of lift, bump stop length and spring length. I am happy with what I have. I don't think anybody is going to agree on anything totally. What one person has and is happy with is not good for another: This is what I have: 2.5" Spring Lift (more like 3.5") 1.25" BL, 1" MML, 2.5" rear Bump stop Extensions, Front 2" extensions, Extended brake lines and BFG 33x10.5 AT's on Crager 15x8 Soft 8's. Also a JKS Adjustable Track Bar and Home made Disconnects. Took a bunch of time on paper, test fitting and calculating before disconnecting and flexing for the first time. I can stuff the tires up into the fender well with touching the stock flairs but yet coming up JUST short of the fender well. That's why I went with 10.5" wide tires. Plus, it rolls with 4.56 gears.|

|HarryJeepGuy||Might want to ask in the JK forum. They are very different on lift VS tire size compared to TJ's.|

I'm getting a 2012 JKU Rubicon. Doing some mods.
• MOPAR front & rear bumpers
• Warn 9000 winch
• 1" spring spacer in the front
• Classic 5 hole Jeep wheels 17x9 w/ 4.7" backspace
• 295/70r17 or 11.5 x 33.4 (?) Nitto Terra Grappler AT
• Bushwacker flat fenders
• other non related accessories
My goal is to get some extra ground clearance with the bigger tires. Go wider for looks and traction off road. However, to do so without rubbing, I plan to run flat fenders and wheels. The 1" spacer is to to level & offset weight of bumper+winch.
I know a guy running 35s with 17x7 and 4.25" backspace, and no fenders without any rubbing whatsoever.
Do you have any concerns about this set up causing the tires to rub anywhere? Could I go with bigger tires, say 35s?
My Jeep is supposed to deliver to the dealer next Wednesday or Thursday, and all of this happen within 1-2 days after.
Thank for your for your help.

Eyes aren't closed, but for someone taking a stock jeep and modding it, the general rules that have been stated are accurate. You can fit any size tires on STOCK suspension if you want to. literally anything can be done. But if he is only touching suspension and is installing a lift kit, not anything custom, then he needs accurate advice to get him what he wants correctly.
I don't disagree with you that 2 or 3 inches can't be run with larger tires, but with stock fender flares and control arms there is going to be rubbing on one side or the other. And if you do add bumpstops long enough to stop it. you aren't gaining any travel over stock. This may not both some. but the whole point is to gain travel and droop.

There's a lot of inexperience/ignorance in this thread along with a few guys that have a general idea of what they're talking about.
Blanket statements that keep being repeated:
Extended bump stops harm overall performance
2" springs are not enough for "offroad", especially with big tires
4"+ is required for 35's
This is on stock rear coils--5" of up travel in the rear
RC 2.5" front coils--6" of up travel
19" @ the belly
More suspension work than I care to list
So what am I missing?
Not saying X amount of lift with Y tires is wrong or right. I'm simply trying to eliminate the blanket statements and open some eyes to other ways of doing things.
|10-25-2011 08:08 PM|
and I agree with you, but you should hit bumpstops before you (fully tuck) otherwise your hitting suspension components or extending/compressing shocks which is all bad.

Adding bumpstop because you run too big of tires with too small of lift is not a good reason to add bumpstop. Bumpstop is fine tuning once you get the most out of your suspension. mostly to keep from destroying things, not just fenders, but others.
I would keep 31s with up to 3 inches. at 3 inches 33s are so/so. I have 33s on my rig, and you can see what I run in my sig.
As mud runner said, its easy to stuff tires with 5 or 6 inches of lift, so 2 just isn't gona cut it offroad.
Okay, so here is how my rig looks on the street. nice little stance, tons of room in the wheel well right? esp compared to MANY jeeps I have seen.
Okay, so here. Looks like plenty of flex right? Nope, still stuffing the other side.

|MUDRUNNER AZ||I can agree with most things on this. But 4 in and 33's with proper bumpstop is what is recommended by engineers (smart ppl) or at least supposed to be. I dont see why you would put on a 2 to 3 in lift then a 2 in or whatever bumpstop on to keep from chewing up the fender and tires. You still have very little travel. A 4 in lift set right is cheaper than replacing tires and body parts. Not starting a fight just an opinion and we all have them. My 6 in lift with 35's. The tire still gets to the fender flare under hard flex so i do need a little more on the bumpstop.|

|TJNewbie||A newly installed a 2.25" Skyjacker BBL, it's just to get me started. My 30x9.5x15s were bald, so I put this on to fit the 33x12.5x15 Duratracs, it does fine on road and dirt roads/trails, I respect my limitations, for now. My new wheels with 3 5/8" backspacing keep them from rubbing things up front and the rear spring perches. Keep in mind that actual tire sizes vary too, the Duratracs that I got were really 32x11x15.|

|AFGUY1980||Get a 2 inch spring and then put a 1 inch spacer in the front and run your 33,s. Then you tires won't look so stuffed and you rake will be level|
|10-25-2011 12:03 AM|
|svtyone||simple if your gonna do anything more than minor flexing you only want to go with 31 or most 32's witha two inch lift. with 31 and a two inch spring not spacer lift front sway disconected i can fully extend and tuck without ever rubbing. you can fit 33's but will have cuts in them if you do any real off roading.|
|10-24-2011 05:55 PM|
|serotina||Seems like a 1" BL, 3.5" SL, and 33x10s is a reasonable and fun set-up for an off-roading daily driver.|
|10-20-2011 02:15 PM|
not just flats, flat fenders verses metal cloak overline are a difference. lol.
but the rubbing is usually from the tires on controls arms, sway bar links, stuff like that. so guys get aftermarket and proper backspaced rims to fix that.

Helped a company build up a TJ with an RE 3.5 inch lift that fits 37; it has MetalCloak overline tube fenders and it is pretty unbelieveable out on the trail!

Edit: you'd be surprised how far 33" tires will take you. I know one guy with an LJ that has 2.5" suspension, 1.25" body lift, tummy tucked, and skids all the way under on 33x12.50x15 tires and leads the "blues and blacks" group on trail rides. He does have lockers but still, it all depends on what kind of wheeling you do and how much money you want to spend.

Stock coils + 3/4" spacers in the rear and RC 2.5" coils up front. 5" up/5" down travel in the rear, 6" up/6" down travel in the front. There's more to this stuff than the tip of the iceburg.
|10-18-2011 02:05 PM|
Yes, I have a 3 inch suspension lift. /75 spacers, 1.25 BL. so all the flex I have is soley from a 3 inch lifting springs. I ideally would have a 5 inch but relocate the shocks and springs, then add custom tube fenders in front and rear to add ground clearance, but keep the jeep LCOG. I think for a 3 inch lift I get a good bit of increase flex, I have actually seen bigger lifts with less travel. I have good droop and uptravel and find that 3 inches is extremely capable for almost anything I throw at it. I plan on keeping the same height lift and only modifying fenders etc for bigger tires and clearance.
I would say the 3.5 should do good for you.

I run 39s on 4" suspension and 1" BL. But......I have a LOT of "custom" sheet metal work.
I would not hesitate to run 35s on a 3" suspension lift with flat fenders.
