My ZHP came with a set of Pilot Sports that now have ~15,000 miles on them. There is heaps of tread left, but recently they have started making so much noise they sound like Super Swampers. Is this related to the cold, or do they all behave like that? The price to pay for grip?

I don't have crazy amounts of noise on my Pilots (also around 15k). I honestly think the Potenza's I had before were louder

i had some worn Pilot Sports on the car when i bought it and they were very noisy. i especially noticed them making more noise between 10-20mph. i even created a thread about it cause i was worried it might be a suspension issue.
i replaced them with Hankook Ventus V12s and the difference is night and day. highly recommend the Hankooks.

check your tire pressures and make sure there is no uneven wear on the tires. Feathering or cupping in the tires can also lead to louder noises from the tires.

This. I'd bet you have feathering on the inner shoulder.Originally Posted by derbo
Take a tread-depth gauge to them. It's not always apparent to the naked eye.

Thanks for the info guys. I had the car in the shop the other day and they didn't notice anything loose/work in the suspension other than a slight leak at the right rear shock. Could that have any impact? I tried to measure the tread depth at different spots, but I will need to pull the wheels to do it more thoroughly. I'll see if I can do that this weekend. By the Mk1 eye, the look even. Tire pressure has been checked and maintained regularly since I purchased her.
Yeah, they are loudest from 15-20 mph, especially when you are slowing down to come to a stop and can't hear the engine singing as much.

The ZHP we have has Pilot Sports. The 325ci has Hankooks.
The Pilot Sports are louder than the Hankooks. My car is slammed too, but no issues. The ZHP will be getting Hankooks.
Whatever you do stay away from KDW those were the worst tire I have ever had. I had a Toyota Tacoma with Mickey Thompson Super Swappers and they sound the exact same. = )

My buddy had pilot sports and they were raucous. He had some cupping due to a bent wheel, but the damn tires were just angry loud all the time. I think mileage is obviously a concern as high perf summer tires aren't guaranteed to go much past 15k miles, but I think age is also a consideration with those tires.
Solution: buy new tires.
