SHAUNO'S TYRE PRESSURE OFF-ROAD TEST! 40 vs 20 vs 15 psi - what's best for each terrain? 

Don't forget that running lower pressures is better for the trails as well, helps with keeping ruts and corrugations to a minimum.

“Length is better than width” Come on shauno, thought that joke was right in your wheelhouse

It never seizes to amaze me how slight pressure change will make a huge difference in the drivability of a terrain. One example on my 80 Series Landcruiser, I always have a default 18psi when tackling Stockton Beach. At that pressure, it drives with ease, even the softer back dunes on the Northern side. But using the same pressure on Blacksmiths Beach, I find my 80 struggling a little. But drop them to 15psi, and it's back smooth sailing again.

And don't forget to adjust the pressures on your trailer if towing. Really makes a difference on sand.

Really happy to see some back to basics tips on the channel. Much better Tuesday episod in my eyes 🤣 I didn't even think about corrugated road pressures so was good to learn

im so happy to see you covering this topic

Great info Shauno. I reckon one of the most important things is knowing your vehicle and tyre combo, and what works - Which you covered really well. Last year we dis a late season crossing of the Simpson - Along the track we got a ranting lecture from an "Instant Expert" who was told by the recovery guys to go no higher than 10-12 PSI. The instant expert then proceeded to launch up a dune, get stuck, then have repeated attempts resulting in an airborne vehicle and camper trailer. 2 days later the instant expert was stranded with a broken chassis. We drove the whole track without going below 20 PSI front and 22 PSI rear and didn't get stuck once - including having to recover some other vehicles. That was what suited our vehicle, tyres load and driving style.

Spot on Shauno, can never say it too many times. Just did a Kimberley trip, lots of on and off, ran 32 psi a couple of times when there was a long stretch of constant changes between black and dirt. Definitely took the edge off but still felt safe cornering on the black top at 100km/h. I generally love stopping to air up or down, reminds me to chill out and enjoy the journey.

Thank you so much for this video I’ve been waiting for something like this!! I haven’t been 4WDing since before my Dad passed and just got myself a Rugged X to relive my amazing childhood memories (holidays) up at DI and Rainbow!! LEGENDS!!!

I had never seen this shown so well. Good job.

Best explanation I've seen so far👍

My starting point when out wheeling is 25psi. If I need to go lower then I will but I've found with the tyres I run, 25psi does me good. Great video Shauno! Tyre pressures are one thing most people don't even think about when they get off the black top. Love your work.

Thanks Shauno very well demonstrated

good job lads, very well taught.

Keep em coming lads

Well put together and explained,

good video guys, good use of actually showing it rather than just talking about it

thanks Shauno, great vid.

nice vid boys u can ALWAYS entertain me when im not ouside keep the good work up when are u going on a track and what track?

Have listened to this will have to put this into practice

Great video guys👍

Can confirm tractor tyres and tracks do not prevent getting stuck. But when you do get stuck you're now proper stuck

Thank you from KSA.

Thanks for the information

Very well presented.

This vid needs to be played on a big screen at the entry to Inskip😂

Cheers from California! Bottoms up!

Another great video guys

that gopro inside the tire shot is awesome

Love the vids

thats smart shauno well done

Taking the rig to Cape York in mid JUNE for 3 weeks with whole my family. Cant wait!

That 5 inch snorkel 😍

Another tip for tyre pressures when picking up a new car from a car yard drive it straight to the nearest servo. Mine had 42psi in each tyre with recommended being 32-34 felt like garbage to drive on the road even every little bump i had the pleasure of feeling.

Where can I buy that stick Shauno ?

Shauno thanks for that grate video just more great information in the bank for me the corrugation are the big one

Its very similar with Fat biking here in Canada, low psi is night and day (4psi vs 8psi) on loose deeper snow. I hadn't considered front to rear tire contact with larger wheels like Tractors rather then just side to side. Great info I had never really thought about on Truck\SUV other then ATV\Dirt bike\Mountain bike which I know tire pressure is everything. (tubeless vs tubed also changes rebound speed dramatically)

Epic video really informative. Question when are we going to see Darrell

Good clips lads, should do a good clip of the most safe and logical way off-road of re-seading the bead..

On ya Dr Shauno 🤙🏽

Good video, do you have one covering options for airing back up again? from occasional/budget use to what appears to be the fancy systems you guys have?

Mate!! I'll be a pro 4x4 driver and owner, before I even have a 4x4😆 Thanks to the videos you fellas keep rolling out🤪🛻🔥🍻👌

Best explanation :-)

Straight down to 15 psi every time I wheel, lower if I need. Bead locks for days 👌

And don't forget to check tyre temperatures from time to time when running softer tyres over corrugations at reasonably high speeds and long distances!

Ive run all terrains at 5psi to get up a long sand dune before. Tried 2 or 3 times at 10psi but was just falling short of the exit. 5psi and straight lines and steady throttle, and it walked up. Id suggest for anyone second guessing ur self, just go lower than u originally thought ud need. Could be the difference between getting out or remaining stuck.

Great info mate.👍🇦🇺❤️🍺

Missing you sooty!!

Don't forget that lower tire pressure also allows more articulation which gives you more grip and keeps 4 wheels down longer, maybe long enough to not need a locker. Here in the orth we start at 10 psi in the snow and go down to 4 with no beadlock and down to 2 with if the snow is really light or has a crust that you need to stay on top of. Making even 1 psi differences make huge differences to whether you get through or have to turn back. CHEERS Steve h.

Great video shauno! But by the looks of that contact patch you could probably do with an alignment. Pretty sure the 200 series has camber adjustment in the front 👌

So Shauno, for example the PDR up in the cape, what pressures AND speeds would you do?

13:33 that better be a fishing rod at the back 🤙

Groundbreaking stuff here boys..

Very informative! I have recently put a video together where I have looked at 4 different ways to deflate tyres. Times are actually very similar between the methods.

we in ca. have a beach cvalled pismo beach, sand for 40 miles against the waves, one day a guy was so stuck in the truck in the sand that even the towing companies alk away from him. i got him out , HOW? a little old school trick, i carry a 20# navy anchor on my truck , lucky the truck had a winch, , i walked off to help, buried the anchor in the sand about 75 feet away and in 30 seconds he was freed, on the other end of the anchor is a length of chain to reecover the anchor from the sand. since then people on the recover trucks in pismo beach,ca have the 20# anchor on board just in case.

Shauna, I am a tyre fitter by trade. This video is very important. It doesn't matter what tyres you run. Those tractor tyres you showed, the smaller of the 2 would generally run about 25-30psi. The larger 1, as little as 12- 16. These pressures are dictated by the weight and type of ground. Good video mate😄😄

Nice video

Don't forget lightweights. Same principals though. 26 in my Suzuki on the road, start at 15 whenever I'm off road.

Love u guys

Liked because I saw a GoPro mounted inside the tire somehow 🤣

Great 👌

60K views! Tire pressure is based on the load. The factory tire pressure is based on maximum load of the vehicle. You can go lower depending on load and speed. No need to go lower than nessary!

17 psi for rocks and 14 for sand for me as a starting point. But every car and every tyre is different. Mine are 12 ply equivalent MTs so have a pretty stiff sidewall meaning I can afford to go lower. Also worth mentioning is the 4psi rule for finding the correct road pressure for your particular set up.

Hey Shauno great article but i think you missed 'profile'. I have 17" rims because that's as small as I can go with my front brakes. For me that means I have to run lower pressures for the same performance of someone on 16s with the same diameter tyres. I have had to tow out heaps of people at the beach who running 18's who think letting their tyres down to 25 or 20 is enough. In my understanding lower profile means less side wall bag and smaller footprint for the same pressure reduction. Also less risk of popping a bead. At the beach i run 18psi leaving a a good safety margin for problems. When towing my 2.5 ton van into a soft sand campsite i'll drop to 10 front and 12 rear. When crossing the Simpson (not towing) i ran 12 front and 14 rear no worries. Over the last 20 years of travel over outback Australia i have developed my 75% 50% 25% rule of thumb. Firstly when fully loaded i footprint my tyres. This is done on a flat surface with 2 bits of card and a tape. I know my fronts run on road at 38psi. I pump up my rears and van tyres (same size as my car on purpose) until they are the same footprint. 56psi rear, 66psi van. When i hit extended dirt 25% drop (all tyres). Seriously rough track 50% drop. The last 25% drop is my emergency get out of Shitsville or super soft/slippery terrain drop. I know there's more there for real emergencies but haven't had to go there often. Considering punctures and tyre longevity the other thing i would mention is speed. Once you have reached the "smooth out speed" on rough roads, for me 65 to 70, don't go faster. Higher speed will turn over more rocks and lead to excessive rear tyre damage and punctures its not worth the hour it saves you . Not to mention the "tyre killers" (big sharp rocks) you hit because you don't have time to avoid them. Not good to run out of spares. I must be doing something right, 20years and over 50000km of towing on remote tracks and no punctures! Shouldn't have said that with a trip coming up this month. Wish I wasn't 10 years younger I'd apply for your filming job offer. Keep up the great content.

Hey Mate, I absolutely enjoyed your video and I just found have Fool I was ...I bought a new kakadu a couple of years ago but honestly I had no Idea how to use it correctly sounds like I have To learn more plz send me more videos how to do off road I'll appreciate it .

I usually run my tires at about 40psi for daily use. But for trail riding, which is a day trip with a mix of terrain and sealed roads of 80km/h I usually just knock it back to 30psi. It's low enough to soften the corrugations, give a little extra footprint but still high enough to run the roads home without airing up. (About an hour's drive). But if I was on a actual off road trip, I'd definitely run much lower.

Yes

With my Suzuki Sierra I Run 18psi on road and 6-10psi when on the rocks. The car only weighs 950kgs combined with big muddies they really don’t bag without dropping pressure extremely low. 👌

What’s the best compressor to buy for reinflating the tyres ?

Keen mate

Here in Northern California, I switched from 12VDC air compressor to a 15 pound CO2 tank for air-ups. I can air-up a 31 inch tire from 18 psi to 40 psi in 25 seconds. My tank refills for 20 USDollars and will fill 20 of my tires, so enough CO2 for 5 sets of air-ups.I have 2 tanks, I take one on short day trips, tank fits behind my drivers seat so it cannot become a projectile in case of issues. Maybe you could comment on the difference between 12VDC air compressors and CO2 tanks? Thanks, or should I say, Tanks.

How’s the build going for sooty mk2 Shauno ??

Sooty the beast

Old Sooty 😔 I'm gonna miss her . Tough Truck she was 💪

i went to black point near where graham went and every car there ended up on 8 psi cause it was just insanely soft and we had alot of different cars so it didnt even matter about how different the cars were

Glad this is still a conversation point, I see so called pros getting this wrong all the time. People would ask me to overinflated their tires and trailer tires, all the time at my old job.

Oy Shauno!!! How do you like the Duratracs???

Any advice on the available TPMS out there?

It will depend on the car weight and tyre size as to the best tyre pressure.

13 is my lowest, popped off a tire between 8-12psi so I won’t go lower

Sooty😭🖤

2.33 "those things never get bogged" me " hold my beer"

We like all off your video And me and dad has been wouch it lost

I air down the Toyotas that come down to the beach once they get stuck. They just don't seem to do that well in sand.

Love sooty

🔥🔥🔥

Oh, what you know, another self proclaimed expert.

This must’ve been filmed a while ago he’s using the original sooty who’s in prices ang being on sooty mk2

3:16 Was that a Daryl cameo I saw?

What if you have 20” rims? How low can I go?

For someone without an air compressor is it worth getting one purely just to get back up to range, or is maybe going 20-30mins on the black top to a servo alright?

What is the best off road pressure for a tyre size 265/65r17 in the dirt , 20PSI or 15? im a bit confused now.

I’ve found my tire sidewalls age out and tear from running pressures too low off road while driving fast. The same wear on road can happen off road if you’re going fast enough. 18psi was too low for my tires for frequent 80-100kmh on corrugations and graded dirt roads. I’ve been sticking closer to 22-24psi for corrugations and non-technical dirt

how is sooty going???

Used to run 20-25psi. Then went to 15, and 10 psi after that. 33x10.5 BFG on a 6in rim. Now on 38x12.5 on 15x8 beadlocks and 2-5psi will be the new norm. On board air is a must.

8:33 i get what youre saying but that was definitely using the brakes then

Why no comment in regards to track/dune preservation to go alongside vehicle damage/ride comfort? Surely with the way tracks/beaches are being closed that should be a more important point than ride comfort.

Let's gooo

Shauno getting all scientific 😉

not something many Australians have to deal with but .. a decent staring point for powder snow ??
