Outer Limits 4x4 Board

just wondering wat a very good beach tyre is one that bags down nicely when put at low presure but will still maintain good life on the road.

this is for a 92 toyota troopcarrier with a 6.5L chevy diesl.
no other mods currently running 31inch dulers(sp).

Muddies IMHO.

im not much of a beach driver, but i always thought that muddies dug in a bit more than an allterain type tyre???

Yeah but it depends how much he's actually gunna go off road.

If he's just going to drive up and down the beach for fishing, his duellers are fine.

I wouldn't be buying muds for a daily driver, if its just gunna be used to drive up and down the beach for weekends.

If you sit there and spin them they will, though the traction/drive they give is a lot better than a HT or AT. A muddie will dig faster, but if a muddie wont drive a section of sand, neither will the others. This is something that I've noticed repeatedly. On the flip side, the muddies do need a little more mumbo to drive them on the sand as the lugs dig a little deeper. I notice this as my JT2's brings on the tranny light at stockton, whereas the other tyres dont.

I wouldn't buy muds either just to drive up/down the beach. AT's will still do the trick and be nicer on the road. Places like Fraser coast is sooo hard packed.

But that wasn't the question.

i found the bfg all terrain really bad on the beach. i never let them down though. the baja claws radials were heaps better.

haha let them down and you would have been fine

IMHO any tire that offers flotation/grip is gonna be sensational in sand

My tyres should be pretty good on sand.....

I've found that muddies act like a paddle and don't bog as easily. Have a look at those 'special' sand tyres on motorbikes and buggies, they're just huge paddles.

Those are some BIG lift blocks you got under them springs .
Nice tyres though .

Oh and I had better add some tech. I had BFG allterains on my lux and found them great on sand at 10psi. I now have Goodyear MTRs and they are good too but do bite in a bit more and dig. I think the thicker sidewall on the MTR may stop it from getting as good a contact patch.

In the Superlift 9" lift kit, you retain the factory block, and add a 2" wedge. So not really a lot, but I would prefer to remove them. I am looking for some drop shackles, as they will lift is 5", so I can remove the blocks.

I have 33" MTR's on my Pajero and run them at 10psi on the beach with no probs at all. When you let down you tyre they actually lenthen to give you a great contact patch rather than bag out sideways (like tank treads).

Disclaimer: 4WD Monthly did a test on this and that's where I got my info from.

from most of my beach driving experience (read stockton beach several times, wet and dry) the key is low pressure 10-12psi. I haven't tried many different tread patterns, but low pressure is a must. We took a 60 up there (petrol), got there at night, let tyres down to about 18psi, went really shiat, in the morning let down to 10psi, difference was huge - drove easy, ended up being the best car there for dune climbing (nothing to do with tyres though).
So, whatever you got, let 'em down, you'll be fine.

Found Cooper St's to be really good sand tyres, but don't be to afraid of low pressures. Also run JT2's with pressures @ 10 psi with no Prob's.

any rubber will work well in sand at low pressure..... bald tyres work really well.... certain rubber needs less obviously than others..

eg my 35 claws compare to previous mtrs... to do the same job eg float around show off passing multiple bogged vehicles in low range first walking beside the car as if pushing was pretty funny at the time maybe not now wranglers at 20 and i would need to drop claws to 16.......... claws like to dig a little any higher than that........ certain ly no to the point of getting stuck but just chewing xtra juice...

answer go a wrangler or cooper from ryano at fourby's marooka..... look good get 33's to help your hiway gearing with that big donk..... look and handle good and of course they need to look good

I've found that A/ts are the go. M/Ts don't bag as weel as an A/t due to the stronger sidewalls. Gof for a bit of size though. I've found 33s and upwards are the best of you have the power to drive them. Very rarely have to let them down.

I have 35" Procomp Muddies for my rd tyres and I have found them awesome on sand..

what ever flicks up the most sand and looks the best!

my 33" claws go fine. dont even need to drop tyre pressure at all. not unless its crazy soft dune type sand, but usually the driving beaches around here dont get too bad...

a week at fraser i probably would though.

10psi is a bit keen for sand, I'd go 20psi and if you have troubles use 1st high and give it revs and don't back off. If that isn't working psi will help a little more but I think if you go below say 14 the improvement is marginal.

My 32x11.5 mt/r's work fine at 20psi, I use the same psi offroad as well and am yet to have issues. I used 20psi on my bald 31x10.5 roadies too, same performance.

You can take cheese cutters at 20 psi over south ngkala rocks bypass on Fraser, I'm yet to find a softer part of sand in SEQ.

It is the driving and not he tyres that makes the difference I feel.

The differance between 14 and 10psi is huge! Your tires will be fine at 10 psi as long as your not thrashing around corners if you are then run 14 but if u want to get as far as possible just keep letting them down

I think it is a good idea to mention if you drop the air pressures greatly like this, reduce your speed to suit. Don't drop them to low pressures and then try to fly around and expect them to stay on the rim. Not only that, at lower pressures, tyre run hotter and there is more chance of damaging a sidewall from running too soft.
Another point to mention is that different tyre sizes and different loads change the minimum pressure you should drop tyres to.
For instance running around on the beach up in the GUlf with a fully loaded Patrol on 33" Claws, we dropped the pressures to 15 in the front and 17 in the rear. We also kept our speed down. I wouldn't have reduced the pressures any more than that.
When I hit the beach at DI in an empty little Mitsubishi trayback with 30" AT's- 24psi all round without any dramas at all (If I even bothered to drop them). When loaded I would drop them to about 18psi.
If you get into some real soft stuff and it feels like it's sinking a bit and the going gets a bit tougher at 20psi... by all means get out and drop the pressures to 14 or so. Just when you hit the hard stuff, pump them back up a bit.

Cheers,
Ryano

I'd be happy if I could find sand that hard to drive, or a beach with lots of corners to thrash around...

I live on the Fraser coast and get to do a fair bit of beach driving.

I have found tall skinny high profile tyres to be the best because the footprint length increases way more than a wide tyre when the pressure is dropped. Its all about the footprint getting longer, not wider. I laugh when people sell their standard skinny wheels for next to nothing to buy wide tyres for sand.

I would have 7.50 16's over say, 10 R15's any day on the sand. Even with a diesel, I can tow through soft sand with 7.50 16's at 18 psi. People often wonder why I dont get bogged, its not so much the capability of the vehicle or driver, its high profile tyres at low(ish) pressures.

The tyres on many soft roaders in particular dont lengthen much at all when aired down because they are a low profile road orientated tyre. And dragging the belly through the sand doesnt help either....

And I've always found that the less tread the better.

we had similar results at the snow. we had a 95'ish paj on 33x12.5 swampers and a diesel 60 series on bald cheese cutters. both were at eight and we found with the paj we had to keep reversing and having second goes when the wheels spun but the 60 would just chug through. maybe this was due to the swampers having such a stiff sidewall and not bulging much or something like that. however when we came to get out of the ruts the swampers did it easily and the 60 was alot harder

Cheers, Calvin

btw i hope the yellow 4by with the big tyres has a trac bar for those spring mount lift blocks

I think the rangers and police up there run tall skinny tyres...

Yeah, I run 31in STs and although they take a bit of a lower pressure to bag decently (hence Pete saying dont be afraid of low pressures), they're really good on the sand.

I suspect thats just what comes on a base spec truck.

I reckon MTRS do great work on sand and rock.

wouldnt run anything with a hugely agressively tread.... they tend to dig in too much
