Hi,

What are the effects (Pros / cons) in case one decides to change the front Tyres to 155 / 65 R12 from the OEM 135 / 70 R 12, the rear being the OEM 155 / 65 R12 ?

Hi,

Note : I am not an owner, I did a long TD a couple of weeks back.

I found the steering hard at parking and low speeds. This is already with the narrower tire, so if you change it to a broader one, from my view the steering effort will increase.

If you change the front tires to 155/65 R12, you will have to change as well the spare, but will it fit inside the bonnet ?

One more point which comes to my mind is with change in tire size, its weight is bound to increase. I suspect that the brake drums might not be of the same size in front and rear. So with increase in unsprung weight, your brake wear will increase and considering that they are drum brakes, brake fade is likely to happen more frequently.

Just my 2 cents. So better check all these factors and let me know as well

Thanks

As per what i have read, nano is prone to oversteer (rear engined, rear wheel drive and all that). The front tyres were made 135/70 R12 to overcome this (front tyres will break away first before the car oversteers).

So, if the front are changed to 155/65 R12, the dangerous oversteer will return (i think)

Checked out the specifications on the Nano site

http://tatanano.inservices.tatamotor...ifications.htm

Brake drums are of same size - front and rear. So that rules out one point from my list.

If I read it correctly, Tata have tried to ensure that the car will understeer rather than oversteer. So they made the rear tire size bigger to provide more grip. So if we increase the grip on the front by increasing the width at front, oversteer might not return considering the amount of understeer dialled into the car.

Tata Nano - Review - Autocar India[/quote]

Yes, Tata have tried to ensure the car will understeer- How?- by making the front tyres small and thin (so that the rear wont step out). Controlling understeer is not so difficult for sew drivers (max, they will scrape against a wall or a car going in same direction). Oversteer is dangerous (will go in for a head-on with oncoming traffic).

PS: I did it from Concorde motors because my friend was already buying his Aria and Nano from there and we coupled it to see what discounts they will offer. We had the worst customer service I have encountered. This is the third new car I am buying in the past 8 years. We had booked two papaya orange paying the advance they stated of 10k each and when 27th came when we were finishing our amounts to transfer, they let us know they sold those available nano's to customers who came and paid full price and we were asked to wait till Jan 10th if we want same color. We felt real bad with the way they treated us but to end this, we said ok to yellow knowing that Jan 10th is not assured date and I wanted to somehow end this interaction with them since my friend was not interested to fight.

It was frankly a torrid experience. Worst till date. Even RF motors their dealer does a better deal than this.

Currently I am staying at NewDelhi for last 3 years, Here the customer experience at Vehicle showrooms are good comparing to the one we are facing at Kerala. I went with one of my colleague to buy Renault Logan, the experience was good. And my friends who went to buy an alto and Ritz, their experience was also good when comparing to what we are now experiencing at Kerala. Customer facing executives need to be properly trained for customer handling and to enhance their soft skills. They not at all bothered about end user experience.

[quote=carwatcher;2616988]Excellent Review GTO,
I am (or now say was) looking forward to buy the 2012 Nano as a second car. But after my B-I-L in Bangalore has bought it for his Dad (CX), he was very disappointed with the engine noise.


The engine noise of nano is still lesser than any other diesel engined car.
I wonder why still people complain about the noise. By designing engine 2-cylindered instead of 3 they have saved at least Rs.10K. Once inside the cabin and doors closed , the engine noise is almost nil.

[ramesh]

I have a nano CX and have also installed central locking , reverse sensors and power windows. Parking the car for long durations ( couple of weeks together ) is common for me. So far in last 2 years I never faced any problems related to battery discharge.I think TATA and their vendors Autocop has done excellent job.

[ramesh]

Dear GTO - You commented that tall tail lamps ( X-Mas Tree styled are outdated ) - But let me tell you these are so usefully effective, whenever I switch on the turn indicator lamps , I see a sudden effect on the rear coming vehicles through IRVM, they start getting away from my turning direction right at the moment I switch on the lamps.I believe this is because the positioning of these lamps at the eye-level height of other drivers.Just because of style such usefullness should not be foregone.

I totally agree.

We need to look at the Nano in a different light.

Those cars too were made with a similar intention - to provide cheap, efficient transport for the masses.

We should be proud that Tata has managed this feat in such a brilliant way.

Recently saw the 2012 Nano.
Was completely blown away by the upgrade in plastics over the previous gen Nano. (Wonder how Tata managed this without an increase in price)
As well as the Paint job - the finish, the colours, the gloss. BRILLIANT.

Superb for a car worth 2.3 Lakhs. Comfort is pretty good too.

Just a status update :

I have crossed 3200 km now. Mileage is 19.88km per litre (full tank to full tank).

I did end up getting a lower mileage of 16kmpl for two full tanks when my dad or sister drove it. They tend to idle the vehicle more and/also end up driving on lower gears or over using the clutch specially if they jump stop it a couple of times. But they too love driving it a lot .

Issues faced so far :
1) 4th gear unless I cross 60kmph, causes vibrations like as if I am in the wrong gear and I need to go back to third gear
2) I have some water vapour in one of my fog lamps. Need to check this out next time I go to the service center.
3) Not giving way, by other vehicles when I try to overtake. Its very irritating. Even bikers tend to think its ok not to give side. So once in a while I really tend to have road rash. But you cant fight the general view of people, so end result is I am becoming more of a sedate driver!

I still have not gone for a over 100km drive at one stretch. Need to do that to see how I feel after it. But so far, I love the feeling of driving it and end up using it more.

No Boss, in my B-I-Ls car, the engine noise INSIDE the cabin was on a higher side and this made him wonder as to if Petrol car is making so much noise, how would the Diesel one fare in this aspect. Maybe he got a piece with bad sound dampening/insulation.
As regards saving of 10K or more, if TML can release the facelift version with almost nil price increase, then why they left out this aspect (engine noise inside the cabin) alone.
If one says that Nano is not a concept car, it is a proper normal car, then it should be treated as one by TML, otherwise the Indian market anyway will show it its worth.
One more aspect which makes me stay away from Nano now is FE, if you go through various posts on T-BHP, you will realise that the FE of Nano is anywhere between 12-20 which IMO is nothing outstanding so as to attract 2-wheeler owners and also people like me who were ready to go for Nano for savings on FE at the cost or poor resale value. I would prefer AT Nano (Petrol) or MT (Diesel).

I have done PUNE-MUMBAI stretch ( 150 kms ) Non stop twice
First ride was in beating sun.
Second ride was early morning

No issues faced at all.

I am happy with the mileage that i have been getting ( In region of 15-18kmpl ) mixed traffic conditions, AC on 70-80% times.
I dont bother to check average nowadays.
Just had to spend 776rs in 1 year ( for changing engine oil, fuel filter, oil filter ) thats it.

Reason is simple , its now do or die situation for project.
My personal experience on FE is - For first 10K km FE was 20~21kmpl ( 90% times single occupant , No AC , moderate traffic ) past 10K FE is improved now it is 22~24 with same driving conditions.

Thats really good. I spent almost 1.5 times that for my Avenger
