Addict,
They are heavy but we dont need to carry them all the time.

Now only I can imagine how huge this can be. Was not so visibly monsterous while fitted in the jeep! Please share some techniques to properly reinforce the tailgate to carry such a huge load

I was referring to the effect of the heavy tire wheel combo on the jeep and steering components, etc..

Looking at the latest pictures of Army 550s posted by parm, it seems that army is now using the Bolero camper style rims for now. They have two holes together a gap and then two holes. Different from the earlier ones in this jeep.

Addict,
2005 onwards, MM550's supplied to army by Mahindra came with disc brakes. That is the reason the new redesigned rims with 5 pairs of 2 holes each, as compared to oval 10 holes individually placed, on earlier drum brake model rims. (marked by red arrow in both pics.)
The disc brake rims dont fit on older drum brake 540/550 models due to the fact that the the holes (marked by yellow arrow in both pics.) do not match, in the latest rims the 5 stud holes are wider apart, compatible only to disc brake models. rest of the sizes are same for 7.50-16 tyres.
However if you wish to still have these rims on your older 540/550 model the way out is, remove all present drums and change to Bolero drums, as Bolero came with discs.

Hi Krishna,

Can you pls post more pictures of the tail gate in your jeep?

I found this Bestop oversize tire carrier installation manual while searching for oversize tire carrier mods. Though it is meant for Jeep Wrangler, i thought it will give some ideas for DIY. Hope this is of some help.61960.pdf

Cheers!

Krishna,

The spare on your tailgate is original, as yours is a army model. Heavy hinges, tubular bracket and all.
Guys like me with older tailgate models have problems of tearing tailgates. For all in the forum with problem I encountered and how I overcame it.

1. welded a 6mm ms sheet to 3/4th rear of the tailgate
2. Inserted a heavy guage pipe full length through the existing pipelike fold on the top part of the tailgate.
3. A Boler damper is (bolted on the tailgate) between the tyre and tailgate positioned where the lower centre of the tyre gets huge support, thus evenly distributing the outward pressure on the tailgate.
4. Additional support comes from the tyre positioned right above the rear tow hook, this takes care of swing due to heavy jerks and bumps.

Trial and error my friends.

May I know how the MRF Sandgrips performs on the road. The treads don't seem to inspire any confidence for moderate to high speeds (Within 100kmph)

Default Mm550xd

Hi Guys,

A few clarifications about the MM550XD
1) They were introduced in 1997(c) with Disc-Brake in the front on 51" Track Width Axles

2) They were fitted with LSD in the rear semi floating axle, 51" Track Width.

3) In 2004 the NGCS MM550XD was introduced with
a) Box-Section Chassis
b) Wider Leaf Springs (Bolero/Maxx-Pikup/Marshal 2000)
c) Full -Floating Rear Axle with LSD with 53" Track Width
d) Open Knuckle Front Axles with new PCD (Scorpio/Bolero) and 57" Track Width.

To Support the Tyre weight you can reinforce the door with a full height plate/vertically orient and weld a U-Channel behind the Tyre Bracket and add 2 L-Shaped Angles under the door, where the hinges for the drop type tailgate were fitted.


Regards,

Arka

When I heard Army rim weigh 16Kgs when compared to regular 9Kg steel rim, I gave up all thoughts on Army rims. That's too much unsprung weight to add to the civilian model I feel.

Samurai,
You are very right about the unsprung weight but there is any difference in the body and chasis specifications of the army or civilian 550?
