Cornering hard does not create uneven wear on tyres. Uneven wear is mostly caused by running unbalanced tyres for long.

^^I'm pretty sure tire wear is caused by weight transfer under cornering. The effect is far more pronounced in cars than larger vehicles where the longitudinal movement causes more wear because of the inability of the vehicle to exert large lateral forces on its tyres.

Here is a document explaining the science behind it (warning: lots of math):


http://archive.pepublishing.com/cont...8577g6k898725/ - another one, a brief excerpt this time.

Once you cross a limit the suspension/tyre combination is unable to maintain the same contact patch as when travelling in a straight line. If you do it often enough or hard enough, you can cause issues.

Also dependent on which tyres we're talking about. Every tyre has different limits of cornering ability and resulting wear will also differ. But when only 30% of the contact patch is being used under severe stress, you can cause uneven wear.

What are you up to? Suicide?
You picked the wrong car for such acrobats.

IMO, replacing the rubber bushes on the lower arm + bushes on the stabilizer bar + tyre change + wheel alignment / balancing should fix the problem.
Remember that 50% of shocks are absorbed by tyres alone and a good tyre reduces the burden on other suspension parts. Maruti's stock tyres are just about average. Go for Michellin or Yokohama without changing the profile.

Ohh, There are lot's of replies and suggestions.
Thanks all dudes.

My tyre is not worn out and still 35 to 40% of the thread is left.
Because out of 29500KM, 70% is run in side bangalore only, and other 30% is only on GQ's ( Bangalore to Chennai, Bangalore to Trichy , Bangalore to Madurai).

So this week I am going to take it to MASS for bush replacement, and Let me check the result on how it goes.

Because Now I don't want to change the tyres and that too when tyre prices are increased almost by 30%.
