'13 V6 Pirelli P-Zero Neros Noisy at Highway Speeds?
Brand new, 235/50-18, very noisy at 60mph+. Temps have been in the mid-40s typically since I got the car, running 35psi. Tires seem to work/handle properly, IOW not a single-tire defect IMO, sound seems to be coming equally from all 4 as best I can tell.
Is this normal for these tires? Is it partly because it's cold enough that the tire compound is stiff/hard to marginal? I can live with it for a while but sure don't like it, just need to know if it's some problem I should bring up with the dealer (prob not). Hard to imagine the "designers" found this acceptable though. Thanks.

^ Strange they're so different. A temp or tire pressure diff? It is very loud, even with the windows up. I should say the tires came at ~40psi and I didn't notice the tire noise then, but then I can't say for sure that I had done any highway driving before I lowered the pressure (only ~150 miles on them now). The 2013 V6s I test drove didn't have these tires, one was a PP and the other a Pony package which did not have Pirellis, it had Goodyears IIRC.

The problem is the tread design and grooved roads. I just read a road test and the testor's were complaining about the noisy tread pattern on grooved highways. I drive on grooved interstates, both vertical and horizontal grooves, and they are terrible. A portion of the highway was just repaved with asphalt, and they quiet down as soon as they transition from the grooved concrete. My Blizzaks are quieter!

Those freakin tires are noisy as hell...and they get worse with wear. Nothing like hearing it sound like an old 4WD truck. I hope i can find much quieter tires. I have never had a car that had such tire noise until I has these last two Mustangs with Pirellis..

I had 2 sets of Pirellis and the second set was no noisy I thought I had a bad wheel bearing. When they wore out after only about 25K miles I switched to a set of Kuhmo Ecsta 4X tires and WOW! They are very quiet and I can hear the engine again. Have had them on for a few months now and have been very happy with them over the Pirelli's.

I've got to wonder if it's a difference in the roads. In Florida where I drive, the tires are quiet on the paved highways, but if I drive on concrete or grovved roads, they produce noise. Since most of my driving is on paved type roads, they are quiet and do not produce any annoying road noise.

D'oh, I think you guys are right, it must be the road type. There is only one nearby road that I drive on over 60. The tires are quiet on the ramp to that highway at roughly the same speed, but turn into whining demons when I hit the highway. I didn't make the association until you guys said it, not enough experience yet.
Kind of OT, but it's no accident these tires came at ~40psi. I say "no accident" because it was apparent to me they checked the car over very well, because I did it later and nothing/zero was amiss or questionable except this. I'm not the only one who got these same tires new at 40psi. I contend they were intentionally put at 40 (instead of the labelled 32) for some reason that I don't know, since a pressure gauge accurate to 1-2psi costs almost nothing and I'm guessing a dealership has one that's not 25% off... We had some other guesses, but I'm going to test if the tires are quieter at 40psi and that's why they did it. I say this because almost everybody who comes to that dealer to buy/test is going to be driving on that "noisy" highway, it's practically right outside the dealership. The tires were noticeably more skittish at 40psi than 35 in our slightly coldish weather.

They might overinflate them to make the ride feel smoother when test driving and taking it home. Bad practice, though, since it's less safe. Maybe theyre trying to get new tire sales from you prematurely.

interesting because at 2100 miles, i just took a 45 mile round trip on a +/- 5 year old grooved concrete highway and thought it seemed louder than my previous smooth concrete / asphalt highway.
