My GS300AWD sounds rough when driving - almost like I have snow tires on or something? Not the smooth quiet sound like the demo car I took home. I took a look at the tires and they appear to be fine, but it sounds noisy when driving.

Has anyone else experienced this? Is there anything that I should check before bringing it back to the dealer?

Thanks all.

 

Have you checked the air pressure on the tires?

 

Do both cars have the same tires with the same wear. Some tires are noisier than others and some get noisier or quieter depending on wear and temperature.

 

They are run flat tires..does that matter?

 

Bingo! Mine sound the same way.

 

The Yoko Advans are noisy tire ........15k max.
they're the highest quality street tires........ just manage to get them in the state recently.
After all the GS is a 4door sports class !!!
