Hi all, wanna ask some questions regarding tyres, as this is my first car and I have never changed any tyres before.

I'm using Axia 2016 AV, till now still using stock tyres.

1- Normally how long do we need to change car tyres in Malaysia? Just normal driving on road, not using it rough etc.

2- If we change, do we change all 4 one shot? or 2 by 2?

3- If let's say 1 tyre is faulty, do we change the 2 tyres at front/back together? or just that one tyre will do?

4- How much will be the price of per tyre for my car?
5- If I buy new tyres from shop, will I get some discount as they will take my old tyres? How much will it usually be per old tyre?

6- What are the recommended brands of tyre for my car?

7- For tyre brands, e.g Michelin, Continental etc., will there be like many series for a car? Or just tell the shop I'm using Axia and prefer which brand then they know which to give?
Like PC DELL laptop there will be Inspiron, G series, XPS etc.

8- How to know which brand is good which is bad? like laptop I can pick easily based on the features, but is there anything special about tyre brands that differentiate them? Anything I should look out for?

9- What are some highly reputable / trusted company that sells tyre in Cheras / Puchong area? Those that will not simply give you marked up prices etc.

10- Anything I should look out for when buying tyres? So that I won't be scammed by tyres seller.

Thank you for taking the time to read and reply this, I just want to clear some confusion before getting them, appreciate it!
