Hi. Anyone know of any difference in road noise between a 19 and 20" tire in the Q7. Also, how is the factory radio in the Q7.

Thanks for any info.

On my Q5 I used to have the Sline 20" now on my S4 I have the 19", same tire and same rim type. I am unable to notice any difference in road noise at all, not to say there isn't but it won't be noticeable.

 

I have a 2007 Q7, and have the 20 inchers. They were slightly more noisy than the 19s that I also test drove, but had different tires. I have the Conti 4x4 Contacts on now, and will be replacing them very shortly with something quieter. Got about 30000 miles out of them
