Are there instructions anywhere around how/what to grind to fit bigger tires?

What about 255/70/17? Do you think you would need to do anything with that?

 

2014 Trailhawk with HS lift and pinch weld mod:

245/75 Mud terrains MT mud tires whatever you want to call them. Rub with 1.5" spacers. Not easily driveable at low speeds. Not good for wheeling or rock climbing.

Pics show gender mount where rubbing occurs. Can add pics near lock where it happens. Also shows chunks from tires. I MAY be able to grind it down. We'll see...

1" spacers on the way for the front wheels. Will update with final verdict.

 

Quick question? (New to the forum) what is the best applicable way to lift a 2014 Jeep Cherokee Limited?
If I posted in the wrong place I apologize in advance.

 

what is the best applicable way to lift a 2014 Jeep Cherokee Limited?

I'd have to say the most practical way is by using a floor jack. They're robust, easy to use, and widely available.

[emoji23] I kid

I vote Hazard Sky lift. It's an already pre-assembled kit, so not much thought has to go into it. And a fraction of the cost of its main competitor.

Agreed, Hazard Sky would have had my money if I hadn't of done it myself long before it was released.

PLUS 3 for Hazard Sky. Cheap, complete, great customer service and so far I am very happy with my lift. It just gives my TH a tad more attitude without screaming "I want to be a JKU" :grin: (sorry guys....couldn't resist).

Since I don't intend to do much more than forest service roads and maybe beach driving it is more than enough. When I finally put some beefier AT tires on it...I will be very happy.

 

I’m going with the hazard sky lift. Thank you guys for the advice.
I have one more question.
I have the shiny 18’s that come with the 2014 limited and I want to put 17’s on I found a great deal on some but I want to make sure they’re going to fit first.
I included a picture of the wheels I want to buy I just want to make sure I don’t need any mods to make them fit.
Also what would be the biggest tire I could run with these and the lift?

Do I just guess on what vehicle you have?


Non TH: 245/65r17-no lift needed
Non TH Lift: 245/70r17-in the back you will want to tie up the liner better, rubs a bit on the side, cut it.

TH: 245/70r17 fit-no lift needed
TH (non TH if you run hazardsky and dobsons?) 245/75r17: trim the back pinch welds, trim the front/back liners, stretch the front liner, full lock may rub, rear tire cover won't sit flat

Larger than 245/75r17: you need to grind the front pinch seams along with everything listed for 245/75r17 and on non TH need to have TH control arms in the back.

Great post on lift kits and tire sizes. My wife just picked up a new 2018 Jeep Cherokee Trailhawk fully loaded white. Looking to get RRO rock rails and bush bar. Getting Duratracs 245 70 17 Natalie’s tomorrow without getting any sort of lift. Mounted one and it looks like there should not be any rubbing on normal day to day driving. I have read if up on two wheels there may be some. Lol. Has anyone had any issues with speedo being of slightly and/or transmission shifting differently. ABS braking or any other computer safety system being impacted by a increase in tire size etc. I will be going from the stick size 245 65 17 to 245 70 17. 1” height diff. Thanks. Any input will be appreciated

 

My speedo is off going from 225/65 to 245/70. On a TH the speedo can be adjusted to be correct I have been told. For me I used GPS to figure out all the speeds (it is incremental at 70 i'm actually going 75 at 25 on the speedo I'm going 26.) No difference in trans shifts. Since my speedo if off my mileage is off and therefor my mpg (I have to math it out to get my real mpg and in the end I lost 1 mpg for all my mods.) I even went as far as taking notes of my trans and cooling temps before and after tires to see if anything was different, no difference in them on them on a trip I normally take.

 

What could go wrong -what year Jeep do you own. Do you have the TECH Package (Lane Deoarture, forward collision, cruise etc). I was curious if the speedo being off would somehow affect those programs. Also curious if there is any lock outs, safety features that would detect the tire size change and shutdown or trigger a system error. (If that makes sense, 2018 seems to have a load of instruments etc).

 

2016 latitude. No tech package on mine. My guess on tech package will have no change because I believe it is radar/sensor controlled. I believe the car doesn't care about speed, it is monitoring distance/objects.

The safety lockout question: People are running cherokees with 32" tires. I have looked into what it takes to do that. This hasn't been an issue for people with shutdowns/alarms/ect. I have run into no issues and since in my research into my vehicle and going through years of posts of people modding it hasn't been a red flag my feeling is that it hasn't been a problem.

 

Firestone’s 245/65/70 out. Goodyear Duratracs 245/70/17 installed (1” height diff). No lift kit. No rubbing yet. Time will tell. Duratrac even fits nicely in the spare tire well. Stock black rims. 2018 Jeep trailhawk white. Full load

 

There isn't a way to calibrate our speedo's for tires above the 29.5" size (245/65R17). I chatted with my dealer and a couple of speed shops last year and the companies that make the equipment won't touch the Cherokee. Doing so would require them to physically break into some stuff on the KL that would without a doubt, void any warranty. So they told me it's not even an option at this time.

In my case, I've learned to adjust my thinking as follows...adding about 1mph for every 10mph on my speedo. So if my speedo says 55mph, I assume I'm going close to 60mph...it's a bit less, but it keeps me safe from any tickets :wink:

 

I have completed a new lift kit for my 18 KL Cherokee today and I thought I would share it with you guys. It works fantastic and cost me around 50 bucks. No need to spend 500 on a MFC kit or even 125 on a hazard sky. This truck is extremely easy to lift. Here is my parts list:

Amazon/Ebay: Rear 1.5inch leveling kit for 2010-up dodge ram 1500. Should get Delrin (plastic) version. Aluminum will be too hard to modify. $25 bucks
Amazon/Ebay: 2 new pinch bolts for the front knuckles: $10
Homemade rear wheel centering kit: FREE. Aluminum spacers for lag bolts I had at work. Could use grade 8 washers as well. No need to spend money on "special" parts.
All said and done I have about $50 bucks in it with shipping.

Very easy to do.
First step jack up vehicle and remove tires and place jack stands
Remove lower stab link nut and push off to the side for now
Remove lower control arm bolt, push control arm down and just take out the spring
Using a drill press or a cordless drill, remove about 1/4 inch of material from the inside of the Delrin spacer from ebay
Install gray plastic cup into bottom of the spacer
Place spacer over spring perch, aligning the tab in the control arm
Re-install spring using floor jack to compress it
put the bolt back in and tighten

Front:
Remove pinch bolt using an E14 socket and a 15mm socket (If I remember correctly)
Push knuckle down exactly 1.75 inches. (I used a bottle jack)
Torque new bolt down to 100ft lbs

Re-attach brake hose and ABS wire (I did this by bending the brackets down a little bit. They went right back into their stock location with full turning and no binding. They are also secure.
That's it! The spacer for the front knuckle is not needed. It is held in place with a pinch system at 100 ft lbs. The rear lift kit is advertised at 1.5 inch, but with suspension geometry it ends up being 2inches. The front measurement has to be exact for the rake to go away and be completely level. You also don't want to have the front higher than the rear. I did end up need the wheel centering kit for this AD1 lift. Instead of buying "custom spacers" I had some aluminum spacers at work that fit fine. They are about 1/2in long and go in between the trailing arm and frame of vehicle to center it. Worked perfectly.
245/70R17 General Grabber AT2 fit great in the front with no rubbing, but WILL hit the front of the rear inner fender without a centering kit.

Other than that, everything worked perfectly. No need to spend $500 on a lift kit!

 

Nice write-up, thanks for the contribution! But you forgot one thing: pics or it didn't happen!

Also a word of caution to anyone following this: the pinch bolts won't necessarily be torqued to 100 ft-lbs, it's dependent on exactly which hardware is chosen. Check torque spec for the particular hardware used.

What is the largest tire size that will fit the AD1 with a stock lift?

245/65r17 with no lift.


I have 245/70r17 with hazardsky lift, max I'd recommend.



I didn't understand "stock lift."

 

Wanted to provide my input since this information is not on the chart. 265/70r17 does not fit with only the Dobinsons lift and pinch weld mod. Front tires couldn't turn due to hitting the front of the wheel wells.

 

I have a 2014 TH all stock right now. I am looking at adding in the dobinson's 1.25" lift for the TH version. Will this be enough clearance to get some 32" BFG KO2's without scraping?

 

If you go narrow, 235/80r17 worked for me. 245/75r17 rubs on engine side of wheel liners at hard over left and right.

Pictures in my garage explain what a strut offset is. The X" lift marketing lingo does not explain the mechanical engineering or the offset used to get said lift.

 

Anyone running 265/65/17 on an AD1? Which lift did you use? Offsets?

Anyone done the analysis if 255/60/18, with 1" wheel adapters, will rub on an AD1? Basically a 10" wide tire at 30" tall. I know this set up works on an AD2.

Thanks

 

With a 2" lift kit installed.

 

5 Tire Rotation

My Trailhawk came with a full-size spare tire, so I want to include it in my tire rotations. I ordered an extra factory wheel from MoparOnlineParts (thanks Benny!) with the TPMS sensor. It should be here this week, and I'll get it mounted and balanced at my favorite local shop. I'm at just over 4k miles, so the first rotation is coming up soon. I also have Gorilla replacement Lug Bolts to go in at the same time- I'll be doing this myself. :wink:

Here is the rotation pattern I'll be using, pattern "G" from Tire Rack:

 

Mark your tires if you don't do your own rotation. Most volume shops/dealers confuse the F in FWD to mean four instead of front. Hence, you end up with pattern F instead of pattern G.

I give them a diagram to follow, but still, they get it wrong a third of the time. Check your lug bolt torque also. Trust but verify.

 

Good reminder! I used to run track days with my cars, so I'm very well-versed on checking brakes, tires, lugs, etc. Also why I prefer to do my own tire rotations. I also need to scrub the rest of the dirt/mud/rocks off the backs of the wheels while I'm at it!

 

What’s the largest tire a ‘19 TH can fit with factory suspension?

@Iron 30.5" is generally what I hear from most posts on here. That should be no to minimal rubbing per crowd sourcing on the forums.

 

Going with the HS 1 1/2" lift and Dick Cepek 265/65/17 tires which come in at 30.6" diameter. Thinking these are going to rub on my TH, but just maybe they won't?

 

@j0e keep us posted if you hear back on those other channels. I've seen enough folks on here go with the 1.5 to 2" lifts that I'm not too concerned about it but would like to know the opinion of the guy making the product. I know it will wear out certain parts faster but is it exponential or extra brutal on the boots or joints to go that extra 1/2 inch?
