Off-Road 4WD Tyre Pressures - Sand, Mud, Rock and Snow

[@geovannebma]

Highway 30-40 psi Gravel/dirt roads 25 - 30 psi Rocky and mud terrain 20 -25 psi Muddy and Sandy terrain 15 - 20 psi Soft sand and mud terrain 10 - 15 psi Emergency situations only 5 - 10 psi Speed warning Rule of thumb: % reduction in pressure = % reduction in speed

[@avpr1c]

Where does Snow fall on this list?

[@melihaksoz]

What about snow mate

[@lilsnoop101]

He don’t know about snow

[@Kizaru208]

@@avpr1c same as sand

[@Christopher-vf6kx]

Depends on the type of snow, temperatue, vehicle weight, and depth of snow. It's its own equation...

[@andreykolakov8813]

Great video! It is very important to reduce the speed when the pressure is reduced. At 5 psi, if there are no beadlock wheels, the tire can peel off the rim.

[@howarddavis6232]

Suggestion - when you start and then drop the pressures, how about showing the Tyres footprint in actual mm. Cheers

[@jimnjele.bean-dayone3505]

Thank you Very concise and to the point !

[@NJSInstructional]

Glad it was helpful!

[@israelestonina5949]

Thank you for making this video!!!

[@NJSInstructional]

Cheers, thank you!

[@beanfrankednow5391]

Best content ever mate!

[@greghill1936]

as well as pressure, the type of tire matters as well. A tire for a 3/4 ton truck might be a load range E, which will not grow much even at very low pressures. I use really soft tires on my Jeep because it's only used for the beach.

[@NJSInstructional]

Great point!

[@sheerwillsurvival2064]

One tip the wider the tire creates more grip so higher chance or stripping tire from rim at low pressure . In my 12.5 wide unbeaded I can only go 9psi safely in my 9inch duratraks I can go 6 psi unbeaded

[@DavidVoxDem]

It doesn't get wider, it gets longer.

[@TWIRKNOLOVE]

@@DavidVoxDem That's not what he's talking about.

[@gordonflash8976]

Great job with the video, Loved it. Just saying it seems you need to be putting a whole lot of power down to spin a wheel inside the tyre, I have run 12 sec quarters on 28 inch slicks at 10 psi and could not get them to spin inside the wheel. But it seems easy to break the tyre away from bead when twisting and turning with low pressures.

[@NJSInstructional]

Cheers, thank you. I agree, breaking the bead is much more likely then spinning the wheel inside the tyre.

[@redpyramid77]

great vid, funny how the auto cc registers the compressor noise as [music] lol

[@simmo8018]

Great vid, is that Wombat quarry?

[@kittenastrophy5951]

I always keep 40 PSI on my M/T tires as on the highway driving when go off-roading since I has had a electric pump in car. I've done inflation by manual pedal air pump at home and it takes too much effort around more than 50 strokes to bring pressure back to 40 PSI. I'll looking for the electric one for the next trip.

[@Sl_king213]

We use high psi 35-40 in deep mud to avoid mud going in to the tyres . Only when doing extreme offroding. It will result in bad offroding performance but you can't change tyres in deep mud .

[@LJMartinez]

Thanks!

[@NJSInstructional]

Cheers!

[@steves7896]

How much ground clearance do you think you lost going from full inflation to 15psi?

[@NJSInstructional]

Great question! Answer is I'm not sure and it would vary between vehicles. I guess it is a compromise, ground clearance vs. traction... a factor to consider depending on the terrain.

[@SNEAKKPEEK1]

Great video! I’m new to off-road and stuff. I have a Jeep with wheels 225/65 R17, I usually use them with 35 PSI in town and highway road. How long should I go when going off road? 25% less PSI? Thank you if you reply!

[@NJSInstructional]

Cheers, thank you. It really depends on the terrain... My suggestion would be to air down a little bit (e.g. 25 PSI), gauge it to your terrain and if you think you need to lower it again, then do so in 2-3 PSI increments. Each small increment should improve traction considerably.

[@محمداسكندراني-م3ي]

Such a helpful video!

[@NJSInstructional]

Glad it was helpful!

[@MrTmax74]

Nice visuals, thank you for the video

[@freeslave8824]

Thanks for you video. Could you please explain a bit more in depth how airing down might improve fuel economy? Thanks!

[@uncleaaron5435]

Are these numbers measured when the tires are warmed up (hot) or are you stating cold air pressures? Thanks!

[@XTrooper3936]

Hello. In your summary, you don't mention a range for snowy conditions. What would you recommend as the best tire pressure range for snow-covered terrain? Thank you!

[@aggyMI]

He does at 3:37

[@JRs-guitars]

There was one very important subject that wasn't covered here...LT tires vs P rated. Even all terrain tires that are P rated...I'd never take them below 15 PSI because the sidewalls are too thin.

[@NJSInstructional]

Good point, LT (Light Truck) duty is critical.

[@steveans]

EXCELLENT Video!

[@DepletedMan]

My suv is recomended to put 35 psi .should i flat down to 30 for gravel

[@NJSInstructional]

My suggestion would be to air down a little bit (e.g. 25 to 30 PSI), gauge it to your terrain and if you think you need to lower it again, then do so in 2-3 PSI increments. Each small increment should improve traction considerably. The lower you go, you introduce other risks like sidewall being more vulnerable to damage.

[@jojiechannel1669]

tnx mate 👍

[@NJSInstructional]

No problem 👍

[@socal69_88]

What compressor are you using?

[@NJSInstructional]

It's an ARB Air Compressor.

[@PerfDayToday]

What air compressor and deflator did you use? Thxs.

[@NJSInstructional]

It's an ARB Air Compressor and Digital Tyre Gauge

[@jean-lucbernois2211]

Thanks vert informative video . How to transforme PSI un BAR ?

[@fatman8435]

1 BAR is around 14.5 psi

[@fatman8435]

1 psi is around 0.068 BAR

[@subthousandoaks]

Ty!

[@jj68131]

Man you can just air dowm with the arb manometer, it’s fast

[@NJSInstructional]

Yes you can, I don't find it as quick however, but more precise...

[@carlossuastegui9168]

Hola, please write in spanish too we don't, understand You , and we Likes yours videos. Thanks You.

[@JohnRivers-ol5tv]

Really Carlos

[@egenestarr1986]

i just watched a real time video proving, that showed lowering tire pressures in snow does worse, in fact the only thing helped was locked diffs / elockers and chains ....

[@caseycovert7345]

why not the width both help

[@vevohoeyo]

Dude you can comfortably run 7 or 8 psi without deadlocks.

[@JohnRivers-ol5tv]

Really

[@TWIRKNOLOVE]

@@JohnRivers-ol5tv not worth the risk

[@nathanpreciado9106]

You said nothing about winter psi

[@TWIRKNOLOVE]

snow = same as sand usually

[@caseycovert7345]

your pressure equals speed theory is double da da dumb. the belts in a tire dont stretch and your speed remains constant

[@markcarpenter3600]

At 20 psi is quite soft it will do amazing contortions. You don't want your tire doing amazing contortions at high speeds! In curves it needs to stand up firm! If you look at the lawsuits involving Ford and Firestone, it came down to under inflated tires, coupled with a heavy load on the vehicle. Ford wanted a soft ride, so the pressure was on the low end. The customer would take it to the tire shop in preparation for a long trip, the tire shop would set the hot tire to the door jam pressure. Now the tire is actually about 5 psi under the door jam pressure, becauseit was hot. Then the customer would load it up to the max and beyond. What could go wrong!

[@DesertGeezers]

I didn't hear you list your qualifications. Why should I believe you are qualified to present a video on this topic ?

[@bekoozler6947]

Cool vid thanx
