How to know when is the time to do rotation?

Sent my 1 year old car with 50k mileage to SC to rotate, SC said no need.

For once I totally concur with the SC and have been practsing so for umpteen decades .
Generally, all my tyres stay in the same 'corner' from new to end of life (of say 115k km) .........
on several different cars till todate .

Edit:Yes, end of life of 115k km for an XM2 at the same corner 'untouched' till its 'end' .
So much on extended tyre life for 'regular periodic tyre rotations' which sounds like a myth to me .

I still dont quite understand, so basically just take off the rim and change position with out taking off the tyre?

Yes, a particular tyre and rim 'assembly or combination' stays intact during a tyre rotation .

But can see the front tyres thinning whereas the rear are still like new.  sweat.gif

It is normal for front tyres to wear faster than rear tyres .
In this typical scenario that happens regularly to most other car models as well , I don't buy the idea of rotating tyres (front to/fro back) with a view to even out the wear pattern so as to simultananeously later replace all 4 tyres at one go .
Instead, I just leave it alone and let the 'worn' front tyres continue its use on same position till say, 1.6 mm tyre depth . By then I would replace only 2 tyres to replace the worn front tyres , retaining and continue to use the serviceable rear set of tyres .By this I think better value for money in tyre replacement is better achieved .

I see no point in the frequently advocated practice of replacing at one go all 4 tyres ! It is not like replacing tyres require so many months of prebooking , and the actual replacement jobs takes weeks to accomplish ..... burning one big hole in the wallet in an instant .

Think about it, what if rotating tires actually wears them out faster?

A tire used to roll forward then gets rolled backwards, meaning it has to be broken in again.
A straight line rear tire from the rear now gets rolled backwards, and driven in the case of FWD tire just gets worn out faster than it should be.

A tire with properly worn in pattern provides better weight distribution during roll, and grip. Imagine if we can change our shoe soles from left to right, we would have to break in the soles again, how that affects treadwear and grip?

One thing worth try, is to rotate only one side front back. Or, cross rotate front left and rear right. Leave the other set alone. See how that goes?

What you say about faster wear after rotating tyres or change 'position' or 'contacting surface profile' or multiple times of 'broken-in' makes perfect sense , IMO . Unfortunately this 'negative' phenomenon is being kept aside or hidden from consumers.
