Finally Reined the 'SNOW LEOPARD', My LineaTjet Plus.

Mr. Shah, I posted this on the tyre thread yesterday:

Nice to read that you are planning to change your tyres even though they have done only 31000 kms instead of the regular attitude of killing the tyre before changing them .

Those prices for the MRF are damn cheap compared to the competition. If you have any good reviews for them you should try them. Out of the other three if the Goodyear Gsd3 F1 are the uni directional one's I suggest you stay away from them as they are quite noisy. I have used the GSD3's but in assymetric tread pattern which are less noisier but were very grippy, both of these are UHP (Ultra High Performance tyres) and will have a stiff side wall so your ride will not be as comfortable.

Yes you can use 205/60 r16 instead of 205/55 r15 on the tjet but the overall diametre of the tyre will increase marginally as there is going to be more rubber/tyre that before. I suggest you stick to 55 as 60 would ruin handling.

 

Thanks Every body for valuable suggestions for tyre-replacement.
It is now sure that the OEM size will be installed and most probably the proper tyres from MRF or GoodYear, depending on the availability at our place and checking those physically would finalize the choice.

@5u3zEr0 , by unidirectional Gsd3 F1 do you mean symmetrical-treads or the V-shaped-treads ? please specify.
For you the very recent picture of my "SnowLeopard"....

The tyre condition is visible in the picture above.

Dr. Shah, your car now looks fantastic with that spoiler now on it. Reminds me of my car before I started the black and white theme on it. Here it is:



About the tyres, Uni directional means that the tyres will rotate only in one direction and hence have to installed in that correct direction. The GSD3 F1 unidirectional treads I am talking about are the V shaped one's.

 

Thanks for your response and efforts.
OK, I now understand the shape of treads, but on pictures I was very much impressed by V-shaped treads, sports look.
This spoiler decreases the FE of the car by about 15-20%.

By black&white-theme, you mean your car was having some other colour ?
I've already seen this picture visiting your thread.

Take Care,
S A SHAH

 

I find the big drop in fuel efficiency hard to digest. How did you check?

No, my car now has its roof and other parts of it painted in black and that is what I meant by the black and white theme.

 

I did check the FE while travelling from Srinagar to Jammu (appox. 300kms) when I made 4th paid service at Jammu-Fiat( the scanned bills will be posted soon).
The FE was >14km/L(without spoiler) and when I travelled back to Srinagar( the spoiler was installed) after service the FE was only 12+kms/L, BOTH TIME SETTING MY-CAR AFRESH.

Can you please post some recent photos of your Jet to have a look of your B&W theme.
Drive safe and belted.

Shah sahab considering that srinagar is at 5k feet and jammu at 1 k, that much difference in FE can be expected between the to and fro journeys. It wont be due to the spoiler.

 

Yes Dear Shams,
Your reasoning is scientifically true, but the physically roads are more or less equally oriented on mountains/hills, it does not seem you are more moving in up-hill direction while travelling from Jammu to Srinagar. Any way, I'll check it here again to establish the fact. Thanks for your valuable response.

 

I agree with @shams. I always get better FE and reach quicker, while driving downhill from Bangalore [~3000'] to Chennai [~20'] than the uphill driving in the reverse direction with the same driving style, route, load and timings in my XUV 500. Here are the details of the last 2 trips.

Very Nice hearing from @J Ravi, yes I agree to the explanation given by Shams, very scientific one.
But my concern here is that the Spoiler(OEM) provided by the FIAT is not properly designed because there is no gap between the spoiler and car body for air passage that would help in car's stability etc. instead the air is striking the spoiler-blade to resist the forward push of the car.

Any ways, @J Ravi , is your XUV500 W8 4x4 or the Forward-Wheel-Drive ?, please don't mind, I think W8 is always 4x4 drive.
With Regards and best wishes and thanking you for your discussion in this thread.
