Tyres offroad
Maybe some food for thought or a rubbish idea....
...... under the impression narrow tyres can sink through the soft mud and grip the hard stuff below the surface, but its always hard getting the non drive wheels out of holes once they have sunk.
do these theories make sense?
Well, let my try & explain it from my <20yrs of offroad & 4x4-experience.
In sand & loose stuff like snow a narrow tyre will sooner dig down & seek grip. That is why U rarely see wide tyres as such in say Norther or Southern Africa. For work vehicles in the Gulf States it is more of that. Those who run wide tyres do it for its BlingBling factor. The hardest offroad event ever was the discontinued CAMEL TROPHY. They ran 7.5" wide tyres on all their land/range rovers. For a good reason. They tackled anything from mud,sand or snow.
The best thing to do when U get stuck however wide your tyre is, is to air down. Is increases the footprint & allows the tyre better grip T: I go offroad with my Land/Range Rovers. The most I have aired down is down to 0.5bar. It requires more care when tackeling obstacles as the tyre flanks get more vulnerable. Also one must show some care not to spin the rim on the tyre.
Look at the big rigs used on Iceland both summer&winter time. They air down too
The ground clearence is more often the problem. If the vehicle sinks down to its floorplans, they are stuck unless axle travel is increased.... The T4 (especially front suspention) is in that matter less than ideal

So if U spin a (fully inflated) wheel to dig down to gain traction U may well bog down sooner that U gain grip T:
Next time U are out cruising the meadows & by-ways, air down to abt 1bar, the ride will be so much more cushyT: Grip immensly improved & if driven right U will have alot less wheelspin (that can cause pricey damage to drivetrain

)
If done frequently, consider investing in a compressor to re-air those tyres... Paddocks stock them for a fair price
