I change tyres based on tread depth and tyre condition. My 11 yr old M800 is running on the OEM tubed tyres at 57000 km . Both tread and the physical condition of the tyres look good.

Both the cars in the family run a lot, so no set of tyres has lasted more than 3 years. Even if they did, I think I would decide to change the tyres based on their condition and grip rather than the age.

I remember the old crappy MRF tyres on my first generation Bajaj Pulsar become hard and loose grip in 10,000 kms. Thankfully, I never had such a bad tyre life from the cars' tyres.

I change tires based on feel/feedback. Too much tire noise/tramline/lack of grip.

Or too many punctures/airloss.

Yoko A-drives: 51,000 Kms & 6 year 5 months old tyres. Tread depth, pattern still looks okay. But, look at next image.<br /> <br /> <a href=Do you change tyres by age or by tread-wear/damage ?-img_20150908_130612160.jpg <br />
Cracks on shoulder of the tyre mostly due to age and partly due to being parked in sun. <br />
These tyres were replaced due to age even though tread wasn't completely worn out.</div>   <div style=

I have been doing the same - change tyres when tread wears off and/or condition is bad.

BUT, a lookover by the naked eye might not give us correct indication about the tyre condition. As I learnt with the 10year, 80000km run tyres of my Baleno. For city use, they were good, but on highways with full load, they gave way. Since I knew that this could be a possibility, I was driving way below my usual speeds, hence nothing untoward happened.

Check out the details at below link.

And a few pages earlier, you can see how all except one of the tyres were looking good tread-wise.

Here is a video regarding unused but old tyres. Used or not max life for a tyre should be
6 years.

In previous years my annual running varied between 40,000 to 60,000 km, so tyres wore out before they aged. I usually replaced as and when tread depth reached the tread wear indication, but if it was during rains I replaced them at about 1mm before TWI. For the last three years my usage has reduced to about 25,000 km/Year that too divided over two cars. My 3 Year old Polo has crossed 50,000 km and is still on stock tyres, but I have noticed some hardening and wear. I expect to complete 60,000 km service my May, and am likely to replace tyres then.
Tyre maintenance. I have always followed 5 tyre rotation at 10,000 km interval, balancing after a large puncture, or whenever I've noticed vibration. Wheel alignment whenever the vehicle has had a deep pothole impact, or when I've noticed abnormal tyre sound, or un even wear. I visually inspect all tyres daily. Interval between alignments can be as low as a few 1000 km, and has once extended to 64000 km on my Tavera.
Two cars my 2005 Innova and 2006 Tavera returned tyre life above 1 lakh km, both had tyres replaced when depth was at least 1mm above TWI as rainy days were due, and I had 1000+ km / day runs due.
My Eco Sport being Petrol has very low use, about 7000 km/Year, and so for the first time till date, I may have to replace tyres due to age and not wear.

What happens is that the old tyres despite having good thread start developing bulges which leads to wobbles and then tyre bursts if not changed especially on the highway.

The bulged tyres if run in the city develop punctures.

We threw away a couple of tyres after they developed bulges and thother two were pro actively replaced in our old Santro which had run anywhere from 46-61K on OE tyres.

I feel it is wise to have a closer inspection done every 10K kms when the tyres are in the process of alignment/balancing/rotation schedule.

If one finds cracks etc along with indications like frequent loss of air; frequent punctures then I guess it is time to change tyres. MRF's especially have good thread left even after miles on them but they tend to get hard developing cracks. As the vehicle is driven, the pressure and temperature increases and it gives way.

One example of me proactively changing the tyres to Michelin Sirac Street from Michelin M45 in a short while was due to cracks developing.

Now I make it a point to check every tyre when I go for balancing/Alignment.</div>   <div style=

Default Re: Do you change tyres by age or by tread-wear/damage ?

Guys,

Am going for a long trip to Konkan this coming weekend and we will be traveling in my Ritzy. Currently it is running on Yoko A-Drives, which has been run for 48,600 Kms to be precise.

I need some urgent advice looking at the state of the Tyre Tread if it is safe to go ahead in it's current state. It does not look that bad but wanted an opinion.

A few 1000 Kms ago, i was having constant punctures [4 in a month]. I had thought of replacing all the tyres but the punctures stopped then. It was probably due to a trip i had done on very bad roads.

Posting the current state of my Tyres below in the following order:

1) Right Rear
2) Left Rear
3) Left Front
4) Right Front.

If the current state is good, would also like to know approximately how many more Kms can i run them.

Appreciate any responses.
Cheers...

Tyre tread depth looks good, at least 2mm depth on all four tyres. Even rubber hasn't deteriorated yet, no cracks seen.
These tyres should serve well for another 10,000 kms if well taken care of.

What I'd advice you is before the onset of the trip, get the tyres balanced, rotated and aligned.

When you are at it, the best of the tyres that have a better thread depth, put them in the front and the part tread depth at the rear.

Expect the tyres to run another 7-9K kms.

@abhi3284. Your tyres seem good, do you do periodic balancing, alignment and rotation. If so go ahead, or else get it done before you start out. The first tyre shows the TWI mark, and tread depth is well over it looks to be atleast 2mm above it, legally you are supposed to replace when wear reaches TWI, but grip reduces when you are about 1mm above TWI.

My Spark is 7 years old and very very sparingly used.Used intermittently within city and weekend drives of 5km or so!.However,I have not left it parked for more than 3 months at a stretch, during my yearly trips abroad..Once after a 2 month idle state,brakes got seized (Hand brake was applied) and A.S.S replaced master cylinders(am I right?) in both rear wheels.
Couple of times we went on highways(Channapatna,Shivsamudra etc).
Vehicle has just **** on Odo(blush)..thats the issue.
Now,I intend to use the vehicle regularly,mostly in city and sometimes on highways(Bangalore/Pondy/Chennai)
As tyres have crossed 7 years is it a safety concern?.Obviously tread depth is intact. If so is it wise to replace all the tyres? Looking at my limited usage,which set of tyres you suggest?
What is the opinion of BHPians? What are my options here?
@Nikhil whats your opinion on this?

Do replace at least the 4 tyres. The tyres would have hardened due to age. With new tyres, you will also find the ride to be better.
