This is very clearly a case of cheating by the tyre dealer. Unless he offered a discount of more than 50% on these tyres and disclosed that this is old stock, he had no business selling such old tyres to an unsuspecting customer. What is worse is JK refusing warranty. If it is not against policy to sell such old tyres then the warranty should be honored. If it is against company policy to sell tyres older than x months then JK should anyways immediately replace the tyres ( because their appointed agent violated company policy ) and penalize the dealer. In both cases the customer should not have to suffer

Since we can't always have a clear picture on how the tyres were stored by the dealer, it is better to avoid tyres that had been sitting for too long. I personally won't choose to buy a tyre older than 1 - 1.5 years even if there are discounts.

Unmounted tyres can have a shelf life of 15 years. If it is mentioned on the tyre, people, especially tyre dealers will misuse it. Even users will try to use them for full 15 years.
The moment rubber hits the road, the shelf life can be around 3 years for a tyre seeing regular heat cold cycle (irrespective of the tread depth) or 10 years for tyres that do not drive much.

That's why tyres or even engine oils etc do not have an expiry date mentioned on them. There is huge difference when they are on shelf and when they are being used. This is my assumption, someone from the tire industry will know better.

The dealers image that the thread owner shared is a big enough proof of how ill kept the tyres would be. They are all stacked one above the other with 7,8 or even more in each stack. The ones at the bottom have a huge load to carry. They cannot be filled with air to support this load either.
The correct way to store them is standing in individual slots on a rack. Again, someone from tire industry can better educate on this matter.

Technically, yes. But in real life, even a car has an expiry date of 10-15 years from the date of its registration and not the date of manufacture.

Here, since JK tyres doesn't have a clearly specified regulation around the warranty from date of manufacture, they should honour the warranty. If they do then they should specify them clearly so the dealer is taken to task.

Since we can't always have a clear picture on how the tyres were stored by the dealer, it is better to avoid tyres that had been sitting for too long. I personally won't choose to buy a tyre older than 1 - 1.5 years even if there are discounts.

The onus is on the buyer to pick up the latest stock, whether one is buying a shirt, a tyre or a laptop.

An aside trivia - In aviation we keep tyres (a) standing vertically, individually, on a rack and even on that rack they are rotated every few days; (b) stored in a dark air conditioned room kept at 17 degrees centigrade. The cold and dark help preserve it from deterioration.

Seems like you’re covered since you have the invoice. Have you quoted this to the manufacturer?

with regards to vehicle dragging to the left?

Imho it is 'usual' to encounter vehicle pulling to one side (left in this case) phenomenon right AFTER a wheel alignment job having green readings all over, not suggesting such vehicle pulling phenomenon as 'normal and acceptable' though.

Without a display of alignment numbers and specific details, my hunch is this vehicle pull phenomenon is alignment related.

We have done all possible matrix to resolve this issue. Now changed all tyres to Michelin and its running straight
Neither JK nor its Dealer bothered to resolve the issue so i decided to pay for my mistake of not checking the date.
Thanks

It is disheartening to note that such malpractices are still employed by tyre dealers putting the customer at high risk of untoward incidents on our horribly maintained roads.

On a side note, since you have a valid bill, have you explored legal recourse? The dealer has sold you a lemon without explicitly mentioning the almost none warranty period and with no discounts suggesting a clearance sale. Suggest that you make both the dealer & the company respond in consumer court with litigation costs on them.

Glad to hear that you've overcome the problem which seems to be not alignment related at the end of the day.

Edit:
After new tyre replacement do you have the wheel alignment checked and adjustment made?

If yes, mind sharing the wheel alignment report?

Your invoice is dated 8 Feb 2022 and manufacture date is 3318 and 5 years to that will be 32 week of year 2023.
So shouldn't the tires be under warranty upto 7 Feb 2023 assuming it has one year warranty?

So what I am missing here?

Hi, Just to clarify - what is mentioned in JK's website is a 5 year manufacturing defect warranty, which is different from Unconditional Warranty (which is typically for a smaller period from date of manufacture). You can check JK's social media handles where they have mentioned that UCW is only for 3 years from date of manufacture. I must admit though that this is very ambiguous and not properly spelt out, I'm able to understand this without much confusion only because I work in the same industry.

Had mentioned the difference between UCW and "regular" warranty in a different post.

Had it been within 3 years from date of manufacture, the OP would have got an instant replacement, like how another BHPian got for his stock Creta tyre (documented below).

Slightly OT, I have always wonderd if my spare tyre will deteriorate due to lack of usage. The spare is mounted on the outside and is constantly subjected to the elements. Should I put it on and drive every once in a while?

If you are maintaining the air pressure, nothing is needed.
Standard rotation process should be followed though.
Even rotation is not needed for some, as spares coming with few cars are of different size and not usable for prolonged duration.

Out here, as per government mandate, tyres have a 5 year sell by date, else they must be scrapped by the dealer. Hence once they are 1 year un sold, dealers offer deals like buy 3 get 1free. After 18 months, its buy 2 get 2. I got a good deal on 4 nos of 275x50R20 Hankook tyres at 50% off regular price of new manufactured ones for 18 month old tyres. Plus a decent amount of cash back via shopping vouchers from a well known supermarket...
