I'm not sure if this is a coincidence, but I recently got four new tyres on my Mazda CX5 2012. On the first day, there were no issues. However, on the second day, I noticed a slight knocking thumping sound coming from under or near the front right tire when I lightly accelerated, like the first 5% of the pedal. If I accelerate any more than that, I don't hear it. On the third day, the knocking sound has developed into a grinding-like sound when I take my foot off the accelerator. When the car is sitting idle in my garage, I am unable to replicate any of the sounds. They only occur while driving and sounds like its getting worse. I have attached a sound file where you can hear the bump and grinding sound. Unfortunately, I cannot get my car to the mechanic until next Thursday or should i take it back to the type shop? any ideas?

Have you checked to make sure the lug nuts are tight?

 

If you didn't have the problem B4 ,that is the most likely area place to look. Simple grab a lug nut wrench and check the lug nuts to see if they are tight. Where did you get the tires ? bring it back to where you bought and had the tires installed and have them look at it ASAP.
