I noticed that the Amby (or one of the bygone Ambassador models) had around 45 BHP peak power; in comparison to today's smaller hatchbacks which have twice as much, those older cars wouldn't have had to deal with this much friction that comes with higher speeds, higher torque etc.

The Bugatti Veyron burns out its rubber after one high speed run. I remember the Mitsubishi Evo variants would do the same as well, though after every 5000 Km, if used sportily. There has to be a similar effect on today's cars as well.

So I just checked the tyres. I couldn't see cracks or bulges as such. I have been doing tyre rotation, balancing and alignment at every 10k kms. The Manufacturing week of the Tyres are 52/17. So its going to complete 3 years (45k kms) in a month.

One of the biggest reason for changing the tyres were that the sound from the road started creeping in more as compared to before.

I do have a road trip planned of around 1000 kms during the Christmas. Considering the increasing number of cases around and new restrictions put in place by the government, I'm not sure if the road trip will take place or not.

My car used to travel everyday for roughly 70-80 kms before Covid. Now the running has reduced drastically. It hardly does 100 kms in a week, unless I feel the need to go for a long drive.

So what u suggest??

Reduced running shall not be a problem. I too don't use my car for weeks or months, at times. And at times, it goes on a 250 to 3000 km trips. When the car is standing for long time, roll the wheels by moving the car by a few meters, every week or 15 days.

When you go for next alignment / rotation, check the tyres from all sides once these are removed. Carefully check for any nails embedded though these may not be causing punctures yet. If the tyres have no cracks / bulges / cuts, if there are not many past punctures, you can continue with these tyres. In such case, continued use for another 10,000 km won't be a compromise.

If you observe any damages on the shoulder or sidewall, scrap the tyres. If you have a past puncture leaking, then also don't take chance. Once on my two wheeler (tubeless tyre), a puncture started leaking next day after repair. The puncture shop removed the puncture strip, reamed the hole again with the tool and packed another strip or two. But the leak persisted. He even glued a patch from inside. But since the punctured hole was damaged and enlarged, no amount of repair could seal the puncture. If you have no such damaged punctures, besides cuts / cracks / bulges, you can continue.

Do the tyre inspection, embedded nails removal and puncture repair at least a week before your trip. This way, you will have time to notice if you have slow leaks after repair.

If all these checks are positive, continue happily. Even a new tyre can puncture, so don't relate puncture in a well maintained 3 year old tyre to it's age.

Witnessed this cut after a long 750 km drive yesterday. I have a return trip planned in 2 days. What do you guys recommend? Do you think it's superficial or deep? I am not keen on a tube inside etc. Continue to use, discard or use as Stepney?

Can you post an image of the 'cut' portion so it can be understood how severe it is?!

My bad. I was travelling, the picture i clicked could not be uploaded along with the post as it's size was larger and i could not reduce its size as i was on mobile. Here it is.

The crack seems to be deep, not superficial. And it is connecting the two grooves. Such crack can cause sudden loss of pressure and tyre blow out even without any foreign object like nail. Also, such wide crack can't be repaired.

Discard the tyre. Anyway, it seems to be worn out past the tread wear indicator. There is hardly any groove depth left.

+1 to what Rahul Bhalgat said.

Also, tread wear does not appear to be uniform. See if there's a problem with the alignment, else your new tyre will also wear out faster from one side.

This query is on behalf of my friend. Request tire experts to guide the next steps.

In his words the problem is below:

"I have grand i10 2017 model. Car has run 21500 kms. When the car goes on smooth road, it has no issues at any speed (0-120 kmph). However, when it runs on rough roads and roads with broken tarmac, the tires make noise like grrrr

And the vibration is felt on the steering as well. No it is not steering shaking because of wheel balancing or alignment.

Kindly help in identifying the issue"

This is normal. On the rough roads, you will hear grrr sound. I have observed this always.



Your friend need not worry

Cross posting from the Baleno thread.
My Apollo Alnac 4G tyres (195 R16) have developed cracks at the sides (shoulders ?). All 4 have those cracks visible. Road noise has increased significantly over the last few months. The car (Baleno petrol Zeta) has run 26 K KM since May 2017 (purchased date). The wheels are rotated, balanced and aligned during the service intervals at Nexa.

What could be the reason. Here are the pics with the cracks outlined :

Need to change Tyres on my Audi A4, currently using the Pirelli Cinturato P7 255/50 R17. Any better options from Bridgestone or Michelin?

[Yieldway17]

Are these dry rot cracks in my tyre? And should I replace it immediately? This is driver side front tyre and other tyres appear to be not having such cracks.

Yes please replace the set more so if you do highway runs. I just replaced my Michelins. All 4 had cracks. Guideline for replacements:

a) Age - a max of 10 years after production date
b) Wear - tread wear indicator visible
c) Physical damage - This includes cuts and large punctures to the sidewall, damage to the tread or carcass for e.g. if the steel belts are visible. Never attempt to get these repaired

Replacement is necessary.

How old are they? If its within warranty, please contact them and get a prorata replacement.
