Rookie Jeep Mistakes?

Ok I have not seen a thread along these lines and think it would help all the new jeep owners a lot. So please all post any mistakes you have made so all can learn from them.

LIKE

1) Never Air down past 12-15 pounds of air pressure without beadlocks.

2) Don't buy a lift with out all the other added things you need.

3) the max amount of back spacing on rims to keep your rig safe 4 1/2".

And here is a video of where I will be saturday wish all you guys could be there.

When you say the max back spacing are you talking about 4.5+ or 4.5-? Just asking for the people who dont understand backspacing.

i believe it's a (-) BS... but there's some guys running 15's that might disagree with the 4.5 number...

that's a pretty bad arse video! when i air down for wheeling i'm down around 14 psi. haven't seen anyone roll a tire off the bead. though in florida... i wonder if i'd ever see that. maybe on more of the hard stuff?

Just asking cause Im runing 3.5 on 37's and wouldnt go with any thing higher my self. If I had 4.5 bs my tires would hit the tub and brake lines in the back b4 I got to full flex.

Please explain. While I won't argue, I cannot think of ONE thing that you LOSE (make worse) safety wise (and a bonus of improved handling and stability with a wider track) other than slightly accelerated bearing wear. (I am running 3.32" on a 15x8 wheel with a 33x12.50 tire).

1) Don't use your clutch under water , cost me a slave cylinder (actually cost the dealer cuz it's still under warranty ) glad that was all that happened (so far).
2) No chrome
3) don't start a thread about what type of lift...., tires or why is my MPG so low

Awesome thread. Honestly. Here's mine: (lame) Don't get the MOPAR side steps; get ACE rock rails instead.

Yep. I dig my 15x8s with 3.75 BS. I think the OP meant 4-4.5 is perfect for 16" wheels.

Don't buy a CAI.
Yeah I said it and I have one. I have the AirAid system. It's a very good product that fit perfectly, excellent directions. This was one of my first mods that I did based on experiences with having one on a power stroke diesel. There's no comparison. It gives the engine a little better sound but after installing the Banks exhaust that was the end of that. I don't think it is bad for the engine but it is not worth it.

if you have a hard top don't forget to undo the washer fluid and wiper harness before removing the top.

That really isn't true. 4.5" is the best for a 8" wide wheel. But backspace is tied to wheel width. While you need at least 4.5"bs in a 8" wheel; it can be 5"bs on a 9" wheel. Of course this all depends on whether you have 17" wheels or bigger. On a 15" wheel you need to stay under 4" so the wheel doesn't rub the caliper with 3.75" as common and 16" not all 4.5" bs will fit for the same reason. Almost all 4.25" or less will though.

For 17" wheel, offset is a better term to use. 0 offset will work on all 17, 18, 20, or larger wheels no matter what the width. Using bs may not be the best measurement because same bs on different width will completely change the stance of the Jeep. Offset is always the same because it measures from center so wheel width doesn't effect the results while bs measures from the back of the wheel and is effected by wheel width

Here's a good start

15" wheel need at least 3.75" bs so not to rub caliper no matter how wide the wheel (some 4" will work but very few)

16" wide wheels need at least 4.25" bs for the same reason as above (some 4.5"bs will work but not all)

That applies to alloy and some steel but there can be exceptions. Most steel 15" will not fit but there are some exceptions.

17" and larger wheel need the following for 315 mm or 12.5" tires

7.5" wide wheels need 4.25 bs
8" wide wheels need 4.5" bs
8.5" wheel need at least 4.75 bs
9" wide wheels need 5" bs
9.5" needs 5.25" bs
10" need 5.5" bs
10.5 need 5.75" bs
11" Not recommended needs 6" bs.

Now THAT is an in depth answer.

Sorry about the pause in my response i had to run to home depo for my DIY quick disconnects. And rics1997 had a spot on point about the amount of BS for rims.

Make sure you are aware there is electrical wiring running under some of the roll bar padding. http://www.wranglerforum.com/f33/dom...ff-153147.html

Beadlocks go on your rims to keep your tire from rolling off the rim when you air down your tires. If you have them you can go down under 10PSI without I would not go under 12-15 PSI.

The first time you take the top off you should not drive for 5 hours you will get a bad sunburn.

A rookie mistake is going to a new trail alone and getting stuck with no one to help with recovery. Hasn't happened to me but had a couple friends that had to call me to come and help them out.

4.5 hours tonight woo hoo lol

The spyderlocks also have a grove on the back side that the tire seats into. They are a pain to break the bead on the backside but well worth it. I air down to 7 or 8psi with my 37's wouldnt go below 12 with the stock rubi tires cause the sidewalls had way to much sag in them.
