Hi sifus, I would like to seek your advices regarding this.

I'll be changing my left rear tyre as it has already reached its wear limit. So I'm wondering if I should also change my right rear tyre for the sake of consistency? It hasn't reached its wear limit yet (still has about halfway to go?) but the thing is that it's more than 4 years old as of now.

The reason both tyres have such a big difference in wear is because my left rear tyre punctured not long ago and I switched to a much older tyre.

Thank you all in advance.

Alright I will consider changing both tyres for peace of mind.

Thank you all for your advice

The puncture was pretty bad, the hole size was about 2 to 2.5 cm, and it happened in the sidewall so it couldn't be repaired apparently
