Anybody had experience on running 18" or 19" tyres for sand driving. Am going up to Queensland in September and will probably go onto Fraser for a day or two. Have RRS TDV8 with 19s and TDV6 Disco with 18" AT2s. Can't decide which one to take as a bit concerned how RRS 19s will go in the sand. What tyre pressures would I run for either tyre? Normally 16 to 18 psi for sand on 16"s, is this a bit low for low profile tyres?

I ran 18" road tyres at 20psi and had no probs in the sand on Fraser. Cheers IanTDV6 HSE (2006 - ARB BullBar, UHF, Sat-Nav, GG AT2's, roof racks, full of fishing gear, kids cra#, and red nail polish on passenger seat from wife painting nails while offroad)

The 18's will go better, BUT a TDV8 has whole lot of more torque. At 18-20 psi at this time of year both tyres won't have any problems. 18s and 19s can run lower pressures (and they need it) than the taller and narrower 16 without rolling off the rim.
Fraser only gets "soft" on the inland tracks in hot conditions.
All IMHO based on my many trips there.

I run 18psi on my V8 LR3's stock 19" Goodyears in the desert. No problems. I think lower would be better (15psi probably best), but can't be bothered to reset my staun deflators...
Thanks for that guys! Still have to decide which car to take!!

Give me the TDV8 - and then your choice will be simple!

G'day Blackperth,
Not much more power and torque than your Disco though you seem to have nearly every accessory on yours. Am tempted to chip mine had any probs? Also notice you have Lightforce spots. I stupidly bought IPFs from ARB and they are pretty useless, not as good as 200 dollar Hellas I have my old Rangy.2.7 D4 eDiff, Traxide Dual battery, Safari Snorkel...Opposite Lock winch bar..extra set 17" wheels with 245/70/17 BFG KM2 MTs..Warrior winch..Long range tank.

Yes, I really rcommend the remap ("rechip" - but I think remapping the software is actually what they do?) especially if you tow anything as thats where I ahve really noticed the increase in torque. Can believe these modern diesel engines - I had previously driven an old shape Prado (90kw?) and what a slug!!!! I think fuel consumption is up a tad bt very difficult to tell as I added the bull bar and LR Tank at same time and that weight makes a difference; I took out the OL Rackmaster drawers on Sunday as they weigh around 50kgs empty!

A bit different- Wheel Alignment
Anybody know of some where in Canberra that can do wheel Alignments. Local Beaurepairs says they can do it, without having the suspension set by dealer? Any thoughts
I've had the standard Goodyear 19's at about 20 psi for soft, wet, "flow-y" sand. They work okay (but not fabulously) on very soft WA sand. On problem is that the rim does roll down on to the tyre, causing the sidewall to flop out. This hasn't caused a problem to the tyres (although it can't be good for them) but three (3!) times it has very effectively found a bit of limestone and managed to slice the sidewall, destroying the tyre. I now have MTR's and run them at about 22psi. They give slightly better floatation and traction than the originals but don't flop out sideways nearly as much and haven't yet suffered a damaging sliced sidewall (for what they cost, I should hope not )Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

marks243 I recently had mine done by ACT Automotive and offroad centre in mitchell - 6241 8011 - they did a great job and I will use them in the future. they are disco friendly too. cheers IanTDV6 HSE (2006 - ARB BullBar, UHF, Sat-Nav, GG AT2's, roof racks, full of fishing gear, kids cra#, and red nail polish on passenger seat from wife painting nails while offroad)

Bagging? This is what you are looking for in sand driving - the more the better. If felt that the Wrangers did fairly well in this, and I ran mine down to about 12psi in the really soft sand at Robe.

And this is the unfortunate result of bagging, and why you have to be so careful with running low tyre pressures. Cant be avoided I'm afraid, unless of course you dont deflate your tyres and you stay bogged.
DiscoJols, IMHO (like all of the abovecomments, of course) there are 3 rules to sand driving - tyre pressure, tyre pressure and tyre pressure. Dont be afraid to run your tyres on whatever pressure is necesary to get them to "bag" nicely (start at about 18psi for the wranglers), and if you get bogged, drop the presures even lower (I've seen a D3 with 18" wranglers "drive out" of a very stuck situation just by letting the pressures down to 8psi - of course the pressures were increased again ASAP afterwards.
Whilst I have done a lot of sand driving, I have not been to Fraser (yet ), so of course I dont know any local issues - but im sure the disco will go great!

I do stand corrected. At a given air pressure (say 20 psi) the MTRs bag out slightly less than the regular Goodyears. The MTRs to date have found limestone when at low pressures but it just scuffs the outside. So when driving on sand with occasional limestone in it (very common in WA but unsure elsewhere) MTRs give more confidence to run at low pressures with less risk to the sidewalls. I haven't yet needed to run the MRTs below 20psi on sand as they've worked okay to date at that pressure.Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

You should give it a test at around 16psi- it's like adding horsepower to your engine. I would think the stiff MTR sidewalls should have no problem with that pressure.
