going by that and using reverse theology of the 31x10.5x15 tyre equates to a


267/76/15.............does anyone make this ???? at least it's close on paper

according to http://www.dakota-truck.net/TIRECALC/tirecalc.html (http://www.dakota-truck.net/TIRECALC/tirecalc.html) 31/10/15 it works out as 255/80/15, which would be very helpful if I had any clue visually what that looks like!

ignoring the price, and the shipping, do any of these visually equate? :supz:

Right then Bulldog, these tyres are 31" tyres on 15" rims.

My Avatar shows my TJ with 33" tyres.

Post by: Bubba on January 16, 2008, 10:11:46 PM
i run 35s but 33s are easyer to make fit
Title:
Post by: Bulldog67 on January 17, 2008, 12:02:30 PM
Right, I think I get it, my original idea was embarrassingly shite  :Hangman: , and I now need anything up to 33's, after that I need to make modifications to fit them (modifications that realistically won’t be happening to 2009!).

If I’ve got that right, cheers dudes, if I haven’t got that right, feel free to throw in the towel of explanation, I may be beyond help!

Hopefully I have something wheel wise in the pipeline, if not, I will be keeping an eye on the sale board.

Again, much appreciated  :supz:

Post by: Lornaben on January 17, 2008, 01:12:49 PM
Modifications WILL be required to fit 33's  :wink:

Minor (free) modifications, if any, required to fit 31's (steering lock bolt needs adjusting sometimes IIRC)

Post by: Bubba on January 17, 2008, 05:00:36 PM
shackel lift and 2 inches of body lift should see33 on both are cheap options 31s should fit rite on

Do you remember the ‘not the 9 o’clock news’ sketch where a bloke goes into a shop to by a ‘record player’, but he aint got a clue what he wants when they start talking about tweeters and woofers? Well, that’s me that is, right here, right now! Im mildly ashamed to say that when i viewed the CJ I looked lovingly at the auto box and big fuk off speakers (that may or may not have tweeters!) and handed over my cash. I have to go from tech virgin to beaten up old tech whore very quickly!

Anyway, I digress, before I once again vacuum my rapidly expanding (expanding via a vacuum - feels wrong although that’s probably just me, scientists explain please!) CJ inspired overdraft, what is a lifted shackle and why do I need it?

There was a time (last week|) when I believed ignorance was bliss, another life rule scrubbed off the list…bollocks!  :supz:

As usual, cheers

Look under your Jeep at the suspension. You'll see something like this...

(http://http://www.4x4wire.com/toyota/reviews/ome/shackle.jpg)

Your leaf springs are bolted straight to the chassis at one end. They are simply allowed to rotate on the bearing.

As you drive along, your springs flex. This makes them longer and shorter as they do so. So at one end of the spring, a shackle (The thing at the end of the spring in the picture) is fitted to allow the spring to extend and contract. As you hit bumps, the shackle sways from left to right (as shown in the pic).

Shackles also have the benefit of raising the chassis and body. This is what will give you clearance for bigger tyres.

Aha, thanks being gentle with me, that wasn’t anywhere near as scary as I imagined!

cheers dude

Ps, greggmo: how much of actual lift? or how much actual taller? whichever you prefer.

cheers to you as well

i am sure we can do em long enough to clear 33,s but bubba will be able to answer that better than me.

Post by: Bubba on January 19, 2008, 11:35:41 AM
