Hi epjx31,

My car is driven less (~5000km per year).
Now my car is 4 years and I think it's time to replace them with new

Here is my situation:
1. 1 total new (used, 4 years old) spare tyre 'sleep' inside my car boot
2. 2 Rear tyres are look healthy
3. 2 Front tyres should retired

I have low budget and here is what I'm planned to do
1. Replace 2 front tyres with new purchase tyres
2. Keep 1 one of my rear tyre, and exchange another rear tyre with my spare tyre

In this case, I will have 2 new tyres as my front tyres,
1 existing rear tyre, 1 unused old rear tyre,
and 1 used rear tyre as spare

May I know if this is possible? Thank you

Thank you HalseyFrangipane



My front tyre is about 3mm:



and rear tyre is above 4mm:



Here is rear tyre measure with coins:



I guess the main problem is about the front tyre which cracked like this:

epjx31,

My questions are:
1. Can I keep using my rear tyre until tread depth become lower?
2. Is my front tyre should be replace asap?
3. If I should replace my front tyre, should I put my existing rear tyre as front tyre, and new tyre as rear? or directly replace front tyre?

Thank you very much
