I have my original rim swap to a winter tire, because the rim that I bought online was too small to fit, mechanic said my DJ has a bigger calliper on the front back it's ok but front no it's hitting the calliper. any specific size that I can look for. 

Thanks, book appointment by Monday they said they will diagnose it where the sound coming from.  

Today I notice a loud knocking sound from the back side on my journey, took everything off even the plate cover It's still there? do you have any idea where is that coming from? I already check the jack are intact and are not moving. Do I need to bring to the dealer to check it?
