2.5 OME, now should I get 31s or 33s...

[jun180]

hi ppl

well after about 5 months of stock ownership im sick of the lack of clearance I have, I continually manage to hit my fuel tank etc on the tracks...(yes I try avoid it!). So I have been looking into a lift/tyre upgrade.

So i found a 2.5in OME kit...and need to make the choice of 31s or 33s ( most likely 12.5 wide for the chunky look!). Wat type of work will be needed with the 31's? shouldnt need much more extra work to fit, but what about the 33s? bit concerned about rubbing etc with tyre width. I know I will need new rims (probably mickey thompson classic style, some cheap copies on US Ebay) and flares. With my research am I right to say I still wont need an SYE because its not a higher spring lift...just an increase in tyre size?

My car is an auto, and its been said that 33s and an auto are acceptable...but is it daily drivable because I rely on the car every day.

Also considering 32" tyres but there dont seem to be many available...any suggestions? I would love to have 2.5" with 32s..

[Jeeps]

I have the 2.5" OME lift and 31's and no driveline issues. :)

good to here! u hve the transfer case drop etc? You werent by any chance in capalaba today were you? I saw your coloured TJ goin into the shops there...I was headed for hammonds!

I have the same as Jeeps, and apart from by gear stick wobbling around a little more than usual there have been no real probs. I would definetly stick with 31's as to run 33's comfortably you would have to fork out alot more. I would just run what you have for a year or two or untill you really get bored of it, then save up and then splurge 33's, ratios, dual lockers 4.5' lift etc. etc...... otherwise you end spending money on breaking driveline components when you could be spending that money on mods instead.

Good Luck

Cheers

you can run 31's or 32's on that kit without any problems as I did for years, with the 3.73 diff gears you have with the auto you could also run 32's, you could also add a 1" body lift for even more clearance if needed

keep in mind max size for a stock rim will most likely be 31x10.5 due to the with of the rim bieng only 7"
you will need a 15x8 rim for 32's and most likely some new flares to cover the tyres

you can get lots of 32x11.5 tyres

I ran 33s with the OME lift + a 1"BL for a couple of years. On full drop the wheels would hit the inside top of the wheel arch. Didn't have any driveline problems. But if you are looking at 33s, or even 32s, you really need to think about getting your ratios done. Try driving down a steep hill in both set ups and you will be amazed the difference ratios make. You can get goodyear MTRs in 32x11.5, but you will need either flare extensions or new big flares. Without the bodylift, I wouldn't go to 33s. If you get a BL and motor mount lift, you don't need transfer case spacers.

[huub]

with the 2.5 inch you rewaly dont gain that much unless you do the sye as well otherwise you still have to use the spacers for the transfer case wich will drop that by 1 inch it acts then like having a big shovel under the car all up with 31inch tyres and a 2.5inch lift you only gain about 2 inches wich is better then nothing but i found it still was to low for any serious 4x4 driving so i reccomend doing the sye as well to avoid the spacers the next good thing is doing a different tank gaurd i used the warn wich gave me another inch at the rear for angels my original tank gaurd looked like a mine field from all the hits it had

No it wasn't me, i don't go near hammonds because i havn't won the lottery lately :)

I do have the t-case drop kit. I find that i no longer scrape on the tracks as the 2.5" lift gets the TJ up and out of the way just nicely, even with the drop kit. A SYE would probably be nice but the drop kit was $50 and took 6 minutes to install. :)

huub yeah i agree with you but unfortunately an SYE is a mod I would do if I have lazy cash, but for now a transfer case drop looks like the go. Im with jeeps on this one, cheap and effective. Im not out enough on the trails to justify the cost.

If I was gonna get an SYE I would look into bigger lift kits etc...but cost is probably the fact that I wouldnt really need a huge lift is why I want the 2.5" lift and moderate tyres.

[Wallace]

i wouldnt run 2.5" with 33's. I hve the 2.5" and a 1" bl and run 32's... and my tyres scrub like hell at full flex, when disconnected.

The OME kit, i think, comes with the trasnfer lowering kit (mine did...)?

Thanks

How did you get "Goodyear Wrangler" soo clean? :hammer:

[Shetani]

After my OME lift I ended up putting in the SYE anyway - just unlucky and had horror vibes, crap gearchange etc. Was also glad to have the belly plate back up where it belongs.

Mine's a 5spd and I won't be going any bigger than my 31's till I can swap ratios...5th is virtually useless except loooong, flat stretches!

how wide are your 32s? Could you get away with a coil spacer or something to help eliminate the rubbing at full flex?

[Shetani]

A coil spacer is only going to help vertically isn't it? So if they're too wide & rub it ain't gonna make any difference, n'est-il pas?

Hi Jun, I run 31x10.5 (on stock rims) with my 2.5 OME and am very happy. I am thinking of doing a BL as well because there just doesn't look like enough clearance between rubber and fender, even though I haven't had any scrubbing I don't disconnect though. YET!)

Also, I don't want to hijack this thread so can anybody help me with SYE questions here;

What ever size tyre over std you plan to run if you flex without extending your BUMPSTOPS you will rub. Coil spacers will lift more, thay wont stop a spring from compressing.

Mud = BAD! :)

This photo was taken about a year and a half ago and i think the tyres had only been on the jeep for a few months without seeing any mud.

[95xjcherokee]

I have just put on 33x10.5's with the 2.5 OME and I like the set up (Ive had 33's for 4 hours now after upgrading from 31's) only rubbing issue is at full lock on full compression.

[jun180]

was just watching some great vids on youtube and 33s seem to be standard lol! http://www.youtube.com/watch?v=8Nq-hNrV4a4

at least with the lift ill be able to fit 33s on later down the track with a few adjustments.

I have decided either 31x12.5 or 32x12.5 tyres what size rim and backspacing should be used? 15x8 or 15x10 and I have no idea on backspacing...I know I will require flares

[millhouse]

stick with 31x10.5 or 32x11.5 on an 8" rim with around 4" of backspace.

[krankieone]

I have ome lift with 1 " Body lift and 20mm bump stop extentions on 3.75" backspaced rims to run my 33 x 10.5 JT's without any rubbing disconected

[uglyprimate]

stick with 31x10.5 or 32x11.5 on an 8" rim with around 4" of backspace.

I'd just stick with the factory rims.

You can get 33x10.5 or 33x9.5 tires as well.

I agree, and I might be gonna open a can of worms here but skinny tyres are better anyway. Except on sand of course. And I know they don't look as tuff. :blah: But they are still better in mud and lose rocks etc.

Yes... of course they are :toilet: :hammer: (note the sarcasm)

[Shetani]

Um, Moorey

I'm actually with you on that...I run 10.5 on all my 4wds...but in all honesty it's a look thing. In sand it's a long footprint you want not a wide one - that creates a wider "bow wave" that saps power to overcome. Sure they're not pretty (or much fun on-road) but the old Dunlop Super Grippers I used to have on Luxes and Troopys will take heaps of punishment in the bush and scramble over rocks & ledges - I'm talking McDonnell ranges near Alice etc.
(Ducks to avoid large can of worms...)

I agree. Sand driving is fun :)
