ok guys, i got a suzi swb with 30" muddies and a rear airlocker.

i ultimately want to put 33"wheels on it for those deep as mud pits cause i got hooked up on my diffs like 4 times on the weekend.

can someone give me a shopping list of things that will need to be done.

like gear ratios and stuff like that.

that would be great.

and any down sides to having 33".

and how far can you have the wheels sticking out the side.

You need to tell us HOW you want to do it.

There's more ways to run a 33 on a sierra than there are sierra's with 33's on them. How much money so you want to spend, how much work do you want to do to bodywork, what do you want to drive?

This setup will be massive cop bait in QLD, but I'm sure you already know that.

You can't "have the wheels sticking out the side" any distance at all legally- they must be covered.

PS - do a search- this has been covered a lot. Read some buildups.

Want33's has lots of tech - search on him as an author on here and in the members page. He has an intelligently built car.

what has your car got on it at the moment?
any suspension lift, body lift?
whats your budget?
it doesnt rain much at all in brisbane so where do you find these mud holes?

I THINK IT HAS A 2" LIFT. NO BODY LIFT.
IT IS SAGGING AT THE FRONT..

BUDGET WOULD BE LIKE 2.5GRAND OR SOMETHING AROUND THERE.

You'll have some fun on a Sierra with a well thought out $2,500.

I'd be thinking of gearing along with your tyres. Both BBM and Locktup 4x4 will be able to help you with this.

Oh yeah,

i dont want the bloody cops harassing me all the time. maybe i should go for some 32" a little bit better centre of gravity... is that just as much work.

what about.

gearing in transfer case.
2inch body lifft.
fix front sagging leafs
and new rims cause mine have go crappy offset.
32" tyres.

whatya think??

Anything with more then 29's is going to look obvious

i got 30" at the moment i just want a bit more clearance. and plus 30" is just a tad to small.

Well I think 34 is a tad too small, but either way, Generally, Cops in QLD are red hot on "big" tyres on 4WD's.

30" is about as bif as you're going to get away with if you're driving it around town regularly in QLD, I think.

Doesn't matter what you've got you are always going to want more. Whether it be tyres, lockers or gearing.

have you thought about shaving your diff?

i havent had any experience on this, but, in theory, if you cut out an inch off the bottom of your diff, you will be getting the same benefits as running a 2" bigger tyre than what you have.

i.e every 2 inches you go bigger on your tyres, you only gain an inch under your diff.


can someone with actual proper knowledge on this either confirm or deny that this will work.

by just cruizin'
It'll work though I'm not sure how much you can shave, should be at least 25mm

It will work, and careful attention to lots of other issues like spring plate clearance, shock mounts, gearbox crossmembers etc can achieve lots of gains when you are tyre limited.

EG - a 2" transfer case lift will allow modification of the gearbx crossmember to run a flat belly pan.

Spring plates like Twisty's 40 series (see his build thread in Members) will clean up this area.

It's worth remembering that sierra's often don't need the large footprint a big tyre permits- In fact, they often perform worse, especially with a 10.5 or 12.5" tyre because ground pressure gets too low, so there is definitely a case for a smaller tyre and clearance gained elsewhere creating a nice outcome, especially where you run the risk of hassles from police.

What about having 2 sets of tyres?

Keep your 30s for around town and normal use, and buy some 33s for the weekend.

If you do, also look into a rattle gun and compressor, makes life so much easier :)

I lurv my 235/85r16 (32/9.5R16) which I've fitted with only guard chopping and a 1/2 Ruf and I reckon I could easily fit 33/12.5 on too because I did cut out a large amount. To me it doesn't look very obvious that it's got very large tyres because of the tyre width, lack of any type of lift and the 16 inch rims kind of helps disguise the size.
Also I'm on the skinny tyre side of tyre width debate because of how they dig in for grip instead of floating in mud and other slippery/loose surfaces. Also less weight and leverage to help bust up CV's on the skinnys too

33x12.5s on a zook makes steering on a stock ( non power steer zook ) pretty tough work at low speeds such as rocks etc i had the tyres from my cruiser on for a day for a test and hated it, i also reckon a skinny tyre goes better , i have just got 7.5x16s they are actually 8.5 wide and 32.5 high and i reckon they go good and there not that obvious with wider diffs under the car

mate it wont matter if you get 32" or 33" tyres on your zook. In QLD they are both illegal and just as noticeable. i say you keep you 30's and buy a set of weekend only tyres as mentioned above
