Check my post below. I am probably one of those rare car owners who had both tyre 'models' on the same car in a relatively short period of time. And feel free to ask should you need more info.

Cheers R2. One last question - did you notice a difference in fuel economy? The Primacy LC tyres were marketed as low rolling resistance but the 3ST's are not.

BTW the P3ST also has the 'X' embossed on the sidewall which denotes a low rolling resistance tyres. My BS Turanzas were standard run of the mill OEM tyres but pretty good ones.

So, over 3 sets of tyres including OE, my car consistently gives me a standard 11-12 kmpl in the city, going up to between 14.5-15.5 kmpl on highway runs.

So even if there has been a positive/negative change I believe it'd be too small (in 10ths of a KM).

YMMV of course. But I believe FE is affected more by other factors such as maintenance/engine condition, car speed, timely gear shifts and judicious use of the clutch, auto transmission or manual, tyre pressure, traffic conditions, use of AC, # of passengers, luggage etc.

All this low rolling resistance marketing talk is just that. If it does make a difference then it's too minor to be appreciable.

Don't base your decision on this.

Did you upgrade finally? Please share the make and price along with dealers considered. Am just getting my s-cross 1.6 and am going nuts thinking about tyre and alloy upgrades. Tyres for better comfort, grip and noise levels ; and alloys for the looks.

Cross-posting from my Ownership thread,

Here is a number comparison between my previous set Goodyear Eagle NCT5 and Current set Michelin 3ST.

Wear and Tear:

Goodyear Eagle NCT5 after 35582



Michelin 3ST after 37200, still it has some good life.



Punctures:

• Goodyear Eagle NCT5, I think it got 4 punctures.
• Michelin 3ST, 2 punctures so far.

Fuel Efficiency:

• During this 35582 Kms on Goodyear Eagle NCT5, the average FE was 15.56
• So far, during its 37200 Kms in Micehelin 3ST, the average FE is 16.27

Note: FE calculated based on the Full tank-Full tank method

Considering that the driving conditions were almost similar throughout, I feel Michelin is really worth the extra money. Also, Michelin offers far better comfort level, is silent and better grip.

Pricing wise both are in different segment though. I compared it because, many ask me about the FE in 3ST as they feel Michelin tyres affect the FE due to its soft nature.

You did mean to say 35,000 kms right? And not 3.5 lakh kms

Thanks revintup. Obviously it is 35K, 35582 to be exact. I have reported Mods to correct the typo.

Thanks Arun - useful ownership data here. As they say, the proof is in the pudding!

I'm planning for a tyre upgrade for my polo with stock size of 185/60 R15. My preferences are Michelin XM2 and primacy 3ST. I had used xm2 for close to 90k kms in my previous cars and I'm really satisfied by it. But recently I heard of good reviews about prima 3st. So I would like try it out. But Their size starts at 196/60. Is it a good size upgrade. I don't want to create any harm to the vehicle with the upgrade.

I am new in buying tyres so I have a query, I recently bought 195/60 R15 michilen primacy 3ST, the dealer billed me for wheel balancing and alignment. Is he correct in doing so, I mean since the tyres are new shouldnt they be already balanced and aligned and even if they are not shouldnot the dealer do it for free since I already paid him for buying the tyres.

Charges for both services vary for each car. Dealer may give some discount but not necessarily keep both services as free. Nothing wrong on his part to charge for these services.

Balancing & alignment needs to be done for the wheel with tyre & not just tyre alone. Balancing is required for even weight distribution, so after mounting tyre on wheel (steel rim or alloy) it gets balanced on dynamic balancing machine. Each wheel will need different amount of weight for balancing.
Similarly, wheel alignment needs to be done after fixing wheels on the car. Toe, castor & camber(not all cars have adjustments for each) gets adjusted during alignment.

How does the 3 ST perform when you take the corners aggressively? Do they roll a lot like XM2? That's my only worry about slapping a set of Michelin on the Fiesta. I really all other attributes of the tyre.

Linea will be a good candidate to judge that. Besides, the Ford is currently on Eagle NCT 5.

The tyres look like they can go on for another 15K kms without any problem.For a comfort oriented tyre like P3ST, 50K is excellent life. Also shows the care you have taken in maintaining them meticulously. What is the interval you follow for alignment,balancing and rotation?

This is way ahead of XM2. It sticks even if you are taking the corners aggressively. However, now after close to 48K on these tyres, its characteristics has changed. But still has tread left for another 10K Kms.

I have done 48K on these tyres and looks good for another 10K. Alignment, balancing and rotation(4wheel rotation) is done every 5-6K Kms.
