Hi all,

I tried to make a recording of tire and road noise after switching my tires to Pirelli P7, but I didn't do a decent job recording.

Is there anyone around that has stock tires (or any other model of tires they'd like to try to record) some evening or weekend? A lot of people are curious about the results, but I feel like I've let them down and want to get better recordings.

I guess I won't exclude the 1st gen Volt too if they want to be recorded. Should be interesting.

That experiment is going to be a little more difficult than you think because you have another variable. The number of miles on a tire impacts its noise.

Yes, I am aware, but the best I can do is try to record multiple cars and report the tire-miles with the videos.

As do varying road surfaces, wear patterns due to improper inflation/alignment, weather, etc..

I'm considering switching to Pirelli P7's on my '16 also, even though the tires don't need replacing yet. Stock tires are just too hard!

I'd be happy to assist. I think recordings are usefull, because only the ear can distinguish between tire & wind noise. So people can get some idea based on the relative difference between? the two noises. Measured values will be meaningless, because of all the variables.

I have 225-45-18 PureContact EcoPlus, that we can compare.
I think they might be louder than stock but handle better. Comfort & Range are too close to call.
Let me know if you want to record the car on your test road.

I have decently high quality microphones, I can do some sort of test in mine, but I would like to mimic other methods to control for as many variables as possible. I'm not in or near California so I wouldn't be able to help in that way.
