YouTube - Off-roading in a 2WD jeep

Experts - please tell me what went wrong and what can be done to get out of such situations.

This is a track where old 4*4 Mahindra jeeps do regular shuttle service, but my new Bolero couldnt handle it.

Thanks in advance.

No traction=no forward motion
your tyres let you down.
all terrain tyres may have helped.
maybe deflating the tyres slightly might have helped.

wait for the experts. they'll be here soon.

True - they are HT tyres, but they are hardly 6000km old.

+1 for Ripper. And what if the tyres are 6K kms old. Only if you had reduced the air pressure by 8-10 psi in each wheel, it would have pulled through. The tyre would have become broader and would have gained traction.

Also you did not keep the momentum going.

just a question, won't the reduction in the tyre pressure while offroading, blow them out?? being tubeless?? correct me if i'm wrong.
i think a much broader tyre & correct driving techniques will help.

+2 for ripper.

The tyres certainly did you in!

They had absolutely no grip and were rotating away to glory!

Nope, it will not. The reduction in pressure will increase the area of contact and will give better traction.

I drive a 2wd scorpio and i know what you must have went through.

if we start blaming in your case,all the following things were culprits-
1.Open differential.(LSD might have helped a bit)
2.H/T tyres.(getting A/T or M/T on 2wd does not make sense at all)
3.Lack of momentum.(its not possible to gain momentum with a 2wd under such circumstances).

a bit OT here: i saw a big dent in your rear bumper. also you managed to scrape your front bumper in the video itself and you seemed least interested. dint you say its your new car?

While we are waiting for the experts, let me add my 2 paise.

1) The A/T tyres wouldn't have helped. I have had couple such situations in my Jeep when I forgot to lock the hubs. The rear tyres (yup, AT tyres) simply dug a hole into the ground even in non slushy mud. Moment I locked the hubs, it moved out smoothly. It needs to both push and pull from both axles to keep the vehicle moving in slushy situations. Besides, most of the weight (hence traction) is on front non-powered tyres here.

2) Torque is not everything, it is almost zero when the tyre starts spinning, especially in open diff scenerio. In slushy inclines, you do need momentum to keep on going. Knowing the right mixture of torque and momentum for a given incline comes only experience.

Thanks for brining this Rough.
It helps us to see the difference between the 4WD & 2WD. I am also waiting for the experts to comment.

[Samurai]

Experts won't see it in this section, moving it to the right section.

Under such circumstances a front wheel drive does much better than a RWD. Putting more weight arond the spinning tyre, like standing on the side footsteps near the wheel might also have helped.

[Rough Square]

Well that dent really hurt. BUt I could'nt express it in the video.

Regarding the front bumper extension coming off (as you noticed in the video), I think the build quality is not what it used to be.

[Rough Square]

Only if you had reduced the air pressure by 8-10 psi in each wheel, it would have pulled through. The tyre would have become broader and would have gained traction.

But would'nt this increase chances of alloy damage?

Tried this, did'nt work.

Hi, I'm no expert, but a few suggestions.

The first situation where in you lost traction at the wheels, you could have tried putting some stones to make the tyres bite. Also, cleaning the tyres sipes help in biting the ground.

You were doing pretty ok and if i were you, i would have continued ahead!

In the second situation, i will hear the sound at home later and post. But from the looks of it, maybe you over revved.

Nothing wrong in trying an obstacle / course again.

Finally, congrats on a nice bolero!
