Outer Limits 4x4 Board

I am going to fraser island in the next few weeks and just wanted to no if people think that my 33x12.5 maxis bighorns will give me problems on the soft sand in a SWB diesel patrol(only 150kg worth of weight on board). was thinking of getting a spare set of AT's for when i go over . just worried about the bighorns sucking what little power my patrol has and making the soft sand driving a pain in the arse. I live at hervey bay and plan on going over 2-3 times a year. Whats everyone think

Right pressures is all you can do.

Oh, apart from give it lots of shit.

keep a set of 31'' at's 4 sand work
cheers steve

Aggressive tyres like to dig - if you don't get the pressure right.

If you do get the pressure right, aggressive tyres grip better.

I had no trouble with 33" STTs at 20 psi.

get the ATs if you can

less aggressive the tyre the better, for sand.

and also the right pressures

cheap road tires are good for sand work. took several stock GU's on club trip with me to Robe and none had issues.

driver attitude, and pressures as stated are your key.

i never had any troubles with my JT2's on fraser at the right pressure... if you get stuck just let a few more psi out..

I've also run JT2's on Fraser and they were sweet even through the sofest stuff at Ngarla that had every Tom dick and harry bogged to the sills. Likewise I've also run HT's and MTR's up there and they were all fine. Probably the JT2's and MTR's being the pick for me.

The JT2's I ran at about 11psi 33x10.5-16
The MTRs at about 16psi 285/75-16
The Michelin 4X4XPC (HT's) at about 20psi.

Really, whatever will work but you just need to drop your pressures.


You'll find that more HT pattern tyres don't dig, but they also don't drive much in the sand. Likewise Muddies will drive a lot better, but when they spin they'll dig quicker - but even with the JT2's they wont send you through to China before you know whats going on.

Spinning wheels? He drives an atmo TD42 with big tyres. No need to worry.


(Don't worry, I feel your pain)

don't worry about buying a second set of tires for the trip just play with your tyre pressures. Get them down nice and low and drive accordingly, no heavy right foot or sharp turns etc and you'll be fine. make sure you have am air compressor with you and an accurate tyre gauge

I went over with our club a few weeks ago, a number of vehicles and different tyre patterns. None of us had any drama's once pressures were down. A couple of randoms had to be recovered, but they hadn't let any air out.

I used to run 31" BFG AT's on the beach up there at 20psi no probs but when i fitted MTRs i had a lot more trouble with digging at 20psi so i now run 12-14psi with the MTRs and they're awesome at that pressure.

i go with the majority. less agressive tread the better.

Save your money on the AT's and fit tubes instead. Then you can safely run down to about 8psi and then you'll hardly be able to spin the tyres. I use to run 10psi with 33 Kumho MT's in the sand all the time (on a SWB GQ, TD42 auto). You can safely run about 15psi without tubes if you are sensible but tube allow you to corner without a worry.
If you travel at about 15psi and get suck, then just drop to 10psi and you'll probably just drive out.

I never had any trouble on Fraser running a set of BFG MT's although watched plenty others have difficulty. Aslong as you have your pressures right, pattern does very little.
