yes you have to make some changes to the suspension. we had to lift the car and bend the leaf springs to fit the tyers.

@GTO, another gypsy was towing that car with the winch.

Cheers,


Maxxis tyres look impressive, they look neat even after such a mud bath. I can see these tyres to have the good self clean properties just like NDMS.

By the way any idea how much does it cost? Are they available in 16 inch version?

@Alpha kilo, thank you, we had a blast in palar, hope to see you next year!

When you ask a question like this it would be best to also say what you are trying to do. Then your question may be answered in the context in which it was asked. Just a suggestion.

im trying to find where i read the inverting of leaf springs. it was about a lot of weight was to be carried and then it was decided to invert the leaf springs to make it compatible to take the weight/load.

i guess many of the dumper trucks have the inverted leaf springs (Kamani is the indian word).

i will try to search the damn thing and try to post some photos of the same!

cheers:

Conceptually, the inverted leaf springs will have the capability to carry more load (remember old brick/mortar bridges are similar to inverted leaf springs in some sense).

Arch bridges are similar in concept to regular leaf springs, remember, the load on the bridge middle area is earthwards and on the same area on a leafspring, the load is skywards.

Most just add more leafs and maybe heavier shockers. The trade off for heavier suspension is really harsh ride like a brick wagon, unless you throw a LOT of money at it.
What are you trying to do?

Exclamation inverted leaf springs

Yes, it is possible to have inverted leaf springs : this is usually done to handle heavier loads. This design is used in the heavier multi-axle trucks and in railway coaches as well. The ends of the leaf springs are mounted on two (tandem) axles and the body of the vehicle rests on the middle of the inverted leaf springs.

But, this is a topic good enough for a separate thread in the " Technical stuff " section .

Please see below links for more info :

Sorry for the OT post.

i havent seen any inverted in light vehicles.

Question What to do when tyres are coated in slush and lose traction

Guys,
I had this small question, say you are tackling a slippery slope in a 2WD bolero, and the rear tyres which the engine powers is covered in slush like this

Mumbai-Pune Offroading Season 08-03082008807.jpg

But it was not this deep in slush, but the gap in the tyre tread was all filled up, and it was like a smooth surface.

And every time you touch the accelerator, the wheels just spun, on and on. Rocks under the tyre really didnít help, the tyres got hot with the all friction.

Tyres are Bridgestone Dueler H/T 215/75/R15, just 6000kms old.

At the end we had to accept defeat and reverse down the trail. Any pointers on how to tackle such situations..

  1. That's expecting tooo much from H/T tyres. No way they will work. Even A/T tyres could have issues in above situation. With H/T tyres, you stand NO chance in slush.
  2. Only option is to use NDMS or M/T tyres. That's it. Nothing else.
  3. Even after all this, you can get stuck in mud. Accept that mother nature is far more stronger than our jeeps/NDMS/M-T tyres.
Cheers,
