A: This is always a tricky question to answer without being there in person. For this reason we recommend going to a reputable wheel and tire shop who has the knowledge to work on this for you. In MOST cases, especially on a recent installation, it will be the absence of Hub-centric rings in your wheels. If this is a newer installation, check hub rings first! If you have hub rings you may wish to return to the installer to ensure all wheels are sitting against the hub of your vehicle, are properly torqued, have the correct hardware and are correctly balanced.
