Door number two.

I'm thinking about getting some 34" or 35" tyres that are notorious for bagging down (any suggestions?) so when aired down to 3-4psi they sit about the same height as a 33" with 15psi.

Possibly a good theory.

MTRs always struck me as a tyre that bagged really well. Not sure that they make a 34" one though.

Perhaps borrow a set of 35's from someone, let them down to 3-4PSI and see how they look?

One thing to consider though, is sidewall damage from running on a tyre that low. Will it shag the tyre out really quickly? Or Wooder's point about no rim protection with bugger all air pressure.

Also the tyre won't bag out at the top either so it will need to be re bumpstopped etc.

Nissan trial last year 1st time Craig had the simex's 1st 2 events 6 rear 8 front and results were very unspectacular dropped to 4 rear 6 front and it was like a new rig bead locks needed though

when running the mt/rs 6 rear 8 front was pretty typicall so tyre type and size aome into play

ambiant temp is a factor if it is a longer event as temp increase so will presuure so start a little lower

Also depends on how new he tyres are....Brand new - which have nice sharp edges - require low pressures to "flex 'em in".......

The grip was absolutely phenominal, however I spend a fair chunk of the day on my transfer case thanks to the low clearance.

I figure a 4" lift with 34"/35" tyres would work, as I would bag them right down to the same size as a 33".

Thoughts?
a flat belly t/case skid would probably be an even better idea
Cal has one on his Tj and the amount of clearance gained underneath is fairly big ...

Wiz: I don't need to get a high clearance skid plate. I've 'adapted' my stock one using rocks.

Interesting point about the top of the tyre SC, didnt really think about it. Sounds like a 34" MTR or equivalent is the go.

Sidewall damage is definitely one thing to consider long term, particularly because I'm looking for a tyre that has a very flexible sidewall. Stronger sideply = less bag.

Dragging it back on topic (for a change) - keeping tyre pressure up to keep vehicle off the rocks?
