I've been using Pirelli STRs and I have no complaints.
The ride is quiet and the tyres seem to be wearing well. (I do not try to extract 'performance' out of this humongous high vehicle)!
I do feel that the sidewalls are more supple in these tyres. They seem under inflated even at 32 psi; to the point where others have, at times, 'warned' me about there possibly being a puncture!

I had Bridgestone A/Ts before and they are great, I got 55,000 kms of life out of them. The BRidgestone H/T Tubed gave me life of 75,000 kms in comparison. My Yokos are 25,000 kms old now, looks like they may have shorter life.

When you say the new Scorpio is better on the bends - it would be nice to know more - is it on account of body roll, suspension set up, middle row comfort, driver handling or any other?
Hey shankar,

What i meant was the new scorpio, the mhawk, is better than the older ones, as the suspensions stiffed up a bit, and the wider profile of the Bridgestones make it a tad better than the older version of the 2.6 scorpio.
Also i have a travelogue with my day to day update about my trip, here is the link:

sure - i understand - the new stiffer suspension makes for a better ride quality around bends etc.
when you say wider profile of bridgestones, did you change from the 235 70 16 which come as stock? I use bridgestones myself but in my case the alloys which are a bit wider than the stock steel wheels make the difference. Also Bridgestone tyre compound is softer and more pliable than the JK Elanzo which is the other OEM choice.
Hence my older 2.6 Scorp corners well and sits tight on the road while taking bends etc. However, sitting in the back, unless strapped in, it does roll and cause discomfort if driven fast-ish.

shall read your travelogue

meantime - all the best! enjoy your scorp!

Guys, as some of you know, I drive a 2.6Dx '04 non-crde scorpio. Its done 67k kms. I get my vehicle serviced and maintained at a local garage who have some decent mechanics who understand what I need. I have not been to the M&M service station in about 2 years.

Now I need to take it back there, as I have need some small things fixed, and can only be done at M&M due to availability of parts etc. Planning to do some things like:

Complete service.

a/c knob light busted (needs replacement).

clutch bush and spring change (clutch plates seem to be still going strong).

engine mounts / nuts tightening (are there some bushes that need replacement here?).

Suspension - the front suspension was completely overhauled at 50k kms (thanks to my over-adventurous driving in Coorg etc.) and feels like new. Now, I sometimes feel my rear suspension needs some work, maybe its just in my head. Can i just change the 'dampers' to new ones? Will this be of any help. What else can be done...leaf springs replacement !?

Engine tuning - here's where i need help. What exactly happens at the service station ?? Whats engine tuning !? I really need to know. Not that anything seems wrong, I feel the engine could be in better nick/tune and a tad less noisy.

Sorry for sounding like a noob, but I really need to know, so that I'm not taken for a ride when those mechs give me some bs.

Thanks in advance !

Scorpio clutch plates are very sturdy and if you are a good river, the clutch plate replacement will come up only after 1 L kms. Scorpio dealers vouch for life of 1.5 L. I changed my clutch plate at 95k as a preventive maintenance measure, it was still good for another 10-20K at that time.

The 2 engine foundations and 1 gear box foundation need tightening from time to time (dealers will tell you that it does not need to!). The foundation itself should be changed at 1L or earlier depending on state of the rubbers. The replacement reduces vibrations tremendously and makes you feel good. Surprisingly, neither the owners' manual nor the dealers have any drill to change this, and you have to tell them to do it.

Check the bush in the rear balancing rod, that is rubber and requires change. Leaf springs require to be recambered every 50-75K. The spring assembly is dismantled, the leaves hammered into shape, the bushes changed and refitted - takes you less than 2 hours. No need to change any leaf unless it is broken.

Engine noise and vibration - check/replace engine foundation, clean injectors, tighten allen bolts in engine tappet cover, but please do not open it. You may check if the tappet requires adjustment.

In case you have not changed the main belt, please do. Advised every 60,000 kms or 3 years. The least you can do is to take out the belt, examine it closely for cracks and change the belt and the pulley bearings.

Thanks for all that info Kumar. I'll definitely get these things done in the service. I had no idea about the leaf springs cambering !! I think i'll get the engine foundations and the belts all changed as well. Not that anythings wrong, but its peace of mind.

@NIP:
I'd go with what hvkumar has said above. Very sound advice.

I'm doubtful about this procedure!
No hammering procedure can ever restore the spring qualities that leaf springs must possess! There will have to be a heat treatment and curing drill!

Standard operating procedure! Have been seeing it from my 1994 Mahindra Commander days. Apparently, the leaves get out of shape/misaligned, so the hammering gets it realigned. Some dealers do it in-house, many give it out to the specialist leaf spring shops.

In my case, I have been doing it regularly every 50,000 kms or so. On one occasion, the M&M guys forgot to put the bushes in between the leaves and the resultant abrasion broke 5 springs at the same time! Over a period of time, with bad roads, the leaves get misaligned and unless you realign it, there is uneven pressure on the leaves ultimately leading to breakages. Even during the recent Ladakh trip, I broke 2 leaves, largely because of an imbalanced suspension (metal fatigue, I guess) - after all, the "temper" (using workshop jargon, presumably to denote the extent of heat treatment - is lost over a period of time and the leaves replaced vis-a-vis the older leaves are of uneven "temper"

Indeed!
There is no way to 'cold service' leaf springs! Hammering achieves nothing but a cosmetic change!
The key to successful operation lies in the correct 'temper', ie the heat treatment, 'curing', shot preening and hardening. Leaf springs are given their properties at the manufacturing stage, and after extended usage or 'fatigue' they need to be replaced or virtually re-built at the factory.
If a stack or a bundle is in use the entire 'set' should be replaced.

Hello,

My trusted Tyre Dealer is offering me Imported Dunlop Tubeless Tyres for the Scorpio. These are 4200 each compared to 5200 for Bridgestore A/T. Does anybody have experience with the Dunlop tubeless tyres for the Scorpio ?

Just curious, any idea how much the leaf springs will cost to replace with new ones ??

IMO, Dunlop tyres are very good, but check on the manufactured date on the tyre so he's not ripping you off with old stock.

Funnily enough, Scorpios come with Bridgestone Dueler H/T tyres, but Xylos come with Dueler A/T tyres! Even my 4WD runs on H/Ts.
