Tata Nexon Ownership Review: Living The Nexon Life

[mayankdixit]

Continued from last post:

Nexon diesel Battery tray rust solution.
I treated rust in this way:
Step 1. Keep on rubbing the rusted area with sandpaper till shiny raw metal shows up.
Step 2. Use rust convertor on still rusted and hard to reach areas.
Step 3. Use metal, antirust primer over this layer.
Step 4. Use automotive grade paint over the primer. Preferably 2 coats.


These are pics after treatment:

Tools used in this DIY.
Its a simple DIY. Not many tools required. I will let the pics speak.

Precautions.
Don't tilt the battery while taking out. Acid will surely leak.
ECU is just touching the battery. Be very very careful while cleaning the tray with soap water. One splash and it can fry the electronics.
Result : Very costly replacement + Owner will look real stupid in his own eyes and in the eyes of flat bed truck operator from Tata etc.

Got used to the rusty look of battery trays since I can remember of, but Doc's job advocates changing that view.

Finally installed the battery back today morning. At least 5 different types of wires .Tricky and scary to work with.
Fired the engine .No CEL .So all happy.



These are the final finish pics. To find out the actual difference between the old pics you may have a look Here

Today while putting back the tyre in the Stepney area of Nexon, I noticed this peculiar thing that Michelin tyre which I have purchased is actually wider by about 1 to1.5cms as compared to Bridgestone. This is despite of them having exact equal width of 215.!!
This is weird. Its as if I have purchased a 225 tyre instead of 215.Now what might be the explanation for this. I searched for all the older pics and there too its very evident. I did not notice it then, why would I, as they were/are exact same specs!!

As of now I don't know if its good or bad. Also I cannot explain it.

OLD vs New

Note in this pic the photo angel is balanced, and here too its obvious that Michelin is wider.

Been through similar confusion. Contact patch would be similar. Took a tape and a calculator and measured and did the math and none of them were close enough to the paper spec

 

[Suryaputhra]

In my opinion its not good. But measurement techniques are different from manufacturer to customers.

Please elaborate a bit more on how it's not good. What you mean by your statement is not clear. We want to learn more.

Many people will upgrade to higher profile tyres. I am not car enthusiast. I am an engineer. I will always stick to design principles. car enthusiasts cite many reasons upgrading beyond design of the vehicle. Many times I suggested stick to car's original tyre profile. Just not tyres ,following manufacturer specs in everything is good, like engine oil, coolant service intervals etc. Higher profile tyres have impact on other parameters not only suspension

 

[deville_56]

Doc, tyres tend to look wider when new, only after fitting the rim, inflating and some use, it forms it true shape. If you check R15 MRF tyres, it looks 130/140 profile at dealer shelf, but once installed it will look like proper 100 profile. I don't think world's second biggest tyre company will bluff about the tyre sizes

I totally agree with you on this, that's why I already replied this to a fellow member on another thread.
You can have a look at this interesting discussion going on there.

Don't do it.
Never oversize tyres.
Never undersize tyres.
Always Stay with OEM stock specs (rims and tyres)
Only changes the rubber quality.
Don't ever go for weird poser rims.
Your ride will thank you later.

p.s. Been there, done that. Ruined the ride .Sold the car. Bitter till today.

 

[deville_56]

But in this case, it's the OE spec tyres of same size and no harm at all.

 

[VISHNUCARCRAZY]

Goodyear Eagle F1 Series tyre also has a similar difference in overall sizing. It appears bigger than what is in specs.

Dear Doctor, you have engineering brains so I like your posts, true investigation, thoughtful, excellent DIY and much more. You are a very valuable member of this forum. As I suggested earlier, Manufacturer measurements are highly accurate its not just like what we measure with scale or tape. when I visited Suzuki factory in Japan 30 years back they are way ahead in terms of organizing the things. If any new model comes no need of minor adjustments in bays. Anyone can see how the measurements done in any factory. In our final year we have subject called Instrumentation it will give you knowledge of industrial measurements and techniques.

I too had similar experience after changing to Michelins in my Nexon last year:

After my yesterday's Chennai>Bangalore drive, I noticed a strange behaviour by Blue Diamond. For the first time, Blue Di showed the distance between my Chennai and Bangalore homes as 354.8 km on the trip-meter. Earlier, it used to show the distances above 361 km. Here, I have compared the past drives, Chennai>Bangalore only via the same route and not vice versa. NaviMaps also shows 354 km and Google Maps, 356 km for the same origin and destination via the same route that I take. Now, Blue Di's trip-meter matches with NaviMaps, Google Maps and my previous XUV 500 within 2 km range. One reason for this change that comes to my mind immediately is the tyre change. Perhaps, the new Michelin Primacy 4 ST tyres are slightly larger than their predecessor, Good Year Excellence, although the specification is the same 215/60 R16. Even a few mm extra could account for this change in the distance due to less revolution of the wheel. There was no software updating done during the recent fifth [paid] service. I will be keenly watching the trip-meter readings from now to confirm my hunch.

The details are here.
