when do you know you need new trucks.
When they are bent, ripped in half, rusted, melted, flattened, incinerated. You'll know if you need new trucks. You can always WANT new trucks tho;)
@Yancy4277 Paris trucks have a lifetime warranty. Try emailing them some pics, and if they ask you to send your trucks in for further inspection they'll send you another pair if they conclude that the trucks weren't run over, purposely bent
