sigh.

OK - For 33's -

OK - the summary of the BS is correct, less BS sticks out, more BS tucks in tighter.

When the tires stick out past the fenders, and you stuff straight up...the tire will hit the fender, unless to cut off that part of the fender, raise it, etc.

REAR - When you stuff one side with the OTHER side drooped, the arc the stuffed tire swings through on the way up, brings the inside top edge of the stuffing tire right at the frame...

...this means that the small BS that makes you rub on straight compression, helps you CLEAR the frame on "opposite side drooped" compression.



Yeah - I know...its a mess back there...

So - for the rear...you can get away with less BS, as most stuffage is one side at a time...unless you do jumps/come down hard off things, etc.

Front -

For the front...because you swing the tire inward and outward to steer...and because the two ends don't affect each other...its a different ball game.

For X's, the rear of the front tires hit the rear of the wells on turns, and even on compression...especially if turned, etc.

One side drooping doesn't impact the other side stuffing...BUT, each tire swings through its OWN arc, up and down.

The difference is that the arc is truncated by the bumpstops, so the compression limit is not whacking as much to the inside, as it is upwards, at the fender, or well top.

So - adjustment of the turnstop bolts to prevent rub on full lock is required... when the tire's end is turned INWARDS.

BL/SL -

For uptravel...again, cutting off the parts in the way, or doing a BL is required.

33's fit nice with a 2" BL...as a 2" BL generally brings the wells up enough for a 4" larger diameter tire to stuff.

A SL can't do that for you, as on compression, the tire stuffs to the same point...with the caveat that it DOES have further to go to get in there...so you CAN get away to a point, just not all of it.



Same with a PML - at ride height, there's room for more rubber...but on stuffage...not so much.

So - really, the job of a BL is to fit larger tires.

The job of the SL is to get ground clearance, and articulation.

The job of the larger tires is to lift the ENTIRE truck, gaining ground clearance for the diffs too, etc...and, to improve traction, and flotation, so you don't get stuck as easily, etc.

So - they all go together towards a common end.

Each helps the other, and the truck, do its job.



PS - I thought the stock alloys had 5.5" of BS.

I'm running 305/70/16's, which are a little fatter treaded, and a little taller, than the same tire in a 33x12.5/15...on the stock 16x7 alloys.

I used a 2" BL to make room, adj the turn stops to stop rub at full lock, cut off a small strip of plastic where the front mud flaps used to mount, and did a 3" SL.

I did essentially no trimming, and it all works.

When I added the Revolvers...due to the extra droop/travel...the rear tires started rubbing on full stuff/droop compression, with the compressed tire against the frame...not bad, but enough to passionately kiss the Lift Lips.

They are getting a little chapped now.

Anyone have pics of 33's on a 8inch wide and 5.0 backspaced rim?

This is my X with a 2" BL and PML. The tires and wheels are Cragar 342's (6 on 5.5 with 4" BS) and tires are BFG AT/KO's 33x12.5x15's.

How much do they stick out?

I'd guess an inch or so...like in the pics.

I have 33/12.5's with 4.75BS and mine stick out about 3~3.5"
He has a BS of 4, I'm betting his stick out about 4~4.5"

I think his would stick out less than yours, remember the more backspacing the less the tire sticks out.

Hey TJ how do you think the truck would be if it had 33's on and 8in rim and 4.5BS with a lift like ours? Minior rubbing?

Right, I have more than his, so mine stick out less, thats what I said

4 sticks out more than 4.75

Unless I'm Lex-ing out again...the 8" rim sticks out about a 1/2" more than the 7" rim....add in one less inch of BS for the 4.5 BS - and that's about an inch and a half further out.

So it would hit for sure on straight compression, and swing out quite a bit wider in its arc....so yeah.

The rear would clear the frame side better stuffed, on opposite side stuffage/droopage situations though.

You could trim more...and turn out the turn stops all the way...but your turning radius will be a bit Queen Mary-like.

My 305/70/16's are a bit taller than, and a bit wider treaded than a 33x12.5/15 of the same tire...and on a 5.5" BS rim, they tuck easily...but, want to nibble at the frame side too.

I could space them out maybe an inch before they'd hit too much....which would make a 4.5" BS at the fender line...and arc into well stuff up front.

If I left the BS at 5.5", and went to an 8" rim...I might JUST make it...If I did both...I'd be hitting left and right.

Its one of those issues I'm wresting with...I'm strongly considering a set of 33x13.5/16 LTB's as play tires...same 1/2" to play with.

Oops i thought you has 3.75 BS my bad

I dont think that my tires would come even close to hit on straight compression, my suspention is too stiff in the rear.

Really? Too stiff to compress?

That's bad...it makes you less stable, as it tips you over to the other side if you can't compress.



I have a Deaver 3 pack AAL, AND a Calmini 2 pack AAL, interwoven with the oem leaves (A progressive 8 pack...)...and I can STILL fully stuff.

What's the dileo on your suspension?

Hmm i have the Ac 3pack AAL. Maybe im wrong, I guess it does stuff but i never get a chance to see it lol but when would the truck do a straight compression both tires comming up into the wheel wells?

Here is another view straight down the body of the X with the tires sticking out. It is about 1-1.5 inches sticking out with 4" BS.

But, if you ask me it looks good!



On a side note, with less backspacing (further out it sticks), you will start to get the rooster tail along the side of your truck. I am starting to notice that with the snow melting around here and the ice on the roads turning to slush.

it adds character

When you finsish that jump of course...



Or are coming down off of a ledge...or are starting UP a steep obstacle, etc.

Luckily, MOST of the rear stuffage is one tire at a time though.

In many states, such as New Jersey and its Reichstags, it is illegal for your tire to protrude past the well/fender....we have to install fender flares to be sure the tire is always in the shade, etc.

It looks good. When i get new tire and rim combo i think ill stick with 33's but on a 8in. rim and 4.5 backspacing. So it will only stick out a bit an inch and a half.

You do know that you live in NJ, right?



Can't stick out...they'll fail your ass.

Gotta tuck in NJ...that's the law son.

Ill throw the stock rims on for when i go to get an inspection
