Outer Limits 4x4 Board

Ill cut to the question, why big rubber?

All i can think of is the bigger the rubber the more clearance the diff has, other than that i dont see the point in getting huge rubber, can someone fill me in?

The reason i am asking is i am considering suspension options. Currently i am running 33" rubber and i am quite happy with them. I was thinking later on down the track i might run 35" rubber, so i am wondering if the extra 2" of diametre (which only translates to 1" extra diff clearance) is worth it? I would rather go out with spacers than raise the suspension to fit the 35's, so i am thinking of keeping the suspension height as it is (pretty much stock), keep running 33" and just get more travel in the suspension.

The rig is a ln106 lux, so i will probably go the ifs rears in the rear and stock rears upfront route, which i believe will move the front axle forward an inch or so? (which would be great, 2" forwards would be ideal as the tyres scrape on the back of the wheel arch full flex) Is there any need for extended shackles with with this option? I believe it will give me about 2" of lift? This i can live with but dont really want to go any higher in order to keep the COG as low as possible.

Any thoughts or suggestion will be great.

It's not only the diff clearance you gain but the surface area. It helps rock climbing and getting over obstacles. Maybe not so much a difference from 33' to 35's but a good difference from stock to 35's.

My 2c, am buggered after writing angry letter to SMH. Going home now.

just imagin a skateboard wheel tring to get up a gutter
compared to a 35

the bigger the tire the smaller the obstical

tim has it

it's all relative to the obstacle

Then you find bigger obsticles to equalise things

Thats the ticket!

True, didnt think of that. So in the grand scheme of things there aint much difference between 33's and 35's.

im considering a backward step from 35s simply for a few extra herbs etc for more touring and less rock hopping/ and as they said the xtra surface area to grab onto obstacles a little is a lot in this case... but in saying that an inch sounds like nothing but it actually is quite a large amt of xtra clearance also....

Wait until you see a 33" next to a 35" and you'll see the difference.
If you drive big ruts, then you'll appreciate the difference.

Well i guess i have to weigh up how hardcore wheelin im going to do against keeping COG low.

Thanks for the info people.

Here is the difference between 28" and 31"
