I'm gonna run a RE 3.5 Super-Ride lift on my 1987 jeep Cherokee with 31x10.50x15 tires. Can anyone with this setup post pics of theirs so I can get an idea of how it looks? Much appreciated!

Mines the super flex though Front 31, rear 33s that are on now.

Ryan, I'll post my experience with the RE 3.5" SR soon. In the meantime, you can look on my profile. It took more than what came in the kit to achieve the results I desired but I'm very happy with it. Put me at 5+" even with shackles to correct the angle some.

Hey guy I have a 99 xj, 4wd, 4.0

Started off with a 3 inch rc lift (yeah yeah I know) with 31x10.5x15

Question is I have a heavy *** bumper and tire carrier with full spare in the back and the back looks lower to me. So I am going to install 1-1.5 lift boomerang iron rock shackle in the rear.

Now for the front I have a 3/4 inch coil spacer I was going to install. I have 3-4.5 inch lift fixed lower control arms, extended brake lines, t-case drop(working on an sye hack n tap for a 242) sway bar brackets, drop pitman.

My thing is will stock upper control arms work for now?

Ryan Riddle

You'll probably be alright for now but it would be a good idea to go ahead and get better ones if you can. Just don't drive it too rough.

'95 xj with 3" rancho lift, Rustys adjustable upper and lower control arms. Stock rims and tires. I bought new rims with BFG 31 10.50 15 tires from big o and now the thing pulls to the right and on braking pulls real bad to the right. With the stock wheels/tires no issues at all. The new wheels are offset outward at least an inch or two more than the stock wheels. Where do I start? Is this normal? It doesn't make sense to me that just putting on bigger tires would cause this pull, but I'm finding out a lot of things on these jeeps don't make sense.

Sounds like a stuck caliper or a flat tire to me. Or possibly one tire larger/ more tread.
Also, would that be big o dodge "under the big american flag on the motor mile"?

For my wheel and tire setup I was going to get 31x10.50 on 15x8 wheels with 3.75" of bs (Pacer 164p). But on the Rubicon Express website, it recommends a wheel with 4-4.75" of bs . So then I found a 16x8 wheel with 4.5" of bs (Mickey Thompson Classic III). I'm getting the RE 3.5in Super-Ride lift and can't decide between 265/75r16 tires with 16x8 4.5" bs or 31x10.50x15 tires with 15x8 3.75" bs. Everywhere I've read, people recommend 3.75" and I want the tires to stick out a little bit but I also want to be able to fit 265s. Any help? What does an xj look like with 4.5" of bs?

I've had both 3.75 and 4" backspacing with my Cherokee, the 4" backspacing tucks into the wheel wells better with 31s than the 3.75 did. I didn't have the 3.75 rims on there long enough to have many pictures, but I still have be 4 on there just with 33x10.5 now.
First two are 31x10.5r15 kos on 3.75
Next 3 are 31x10.5r15 kos on 4"
Next to last is 31x10.5r15 ko2s on 4"
Last is 33x10.5r15 ko2s on 4"

Also should note, all but the last are on a 3" rough country lift, and the last one is a 4.5" lift in the front and 5.5" in the back all pieced together, but with rubicon express springs.

None of the above. No issues at all with my stock wheels/tires. Something about the bigger tires with a different offset is causing this pull. I was hoping someone here has had the same experience and could give me a heads up as to where to start. My Big O guy is pretty savvy when a situation like this happens on changing up to bigger wheels/tires on various vehicles, so I guess I'll just have to let him have it for a couple days

Try switching the tires from the driver side to passenger side and see if it makes a difference.

If it still pulls to the passenger side with no change, I'd consider the idea that your ball joints may be worn and the larger/heavier tires are applying more leverage and exacerbating a problem that you hadn't noticed yet. That's purely speculation, though

That was actually one of my first thoughts on swapping the tires around, but they're brand new for hell sakes. Worth a shot though. I'll check those ball joints but I think they're ok. I put the stock wheels/tires back on and it drives perfect. Very strange.

Hey NewKind, I have a '76 Kaw KZ900 LTD I've had since '78. Lots of good(and some bad) memories on that beast. They are getting pretty collectable these days.

NewKindOfClown

It's possible that a wheel could be bent, or a tire may have a defect in the rubber compound or the cords. I'd definitely try swapping them around first, and you may need to warranty one of them.

I inherited the bike when my grandpa passed. He bought it new, but it's been sitting for almost 20 years. I'm gonna gain a lot of knowledge fixing it up

Okay one more question....With the RE 3.5 Super-Ride kit with 31x10.50 tires, 15x8 wheels, will there be enough clearance with 3.75" of bs? I'm trying to avoid rubbing and I don't want to trim the fenders.

SatiricalHen

If you have stock bumper caps they'll probably rub, flexing out 3.75 will probably contact the fender/fender flare where the higher backspacing will tuck into the fender. You can bumpstop more to avoid the flexing issue, but the rubbing on the bumper caps may need trimmed.
