Mine have held up for almost a year and a half and still going. Most people say they're very quiet, but I hear quite a bit of road noise from them. Might just be a random set of noisy tires. As for traction, they hook up great, just like gregtommy said.
440? I bought 275/45/r17s nt555r drag radials from discount tire directs eBay store for 350 for a new set. So I wouldn't waste ur money. Especially not of they're brand new. For a good street performance tire I'd say they are good, but for a drag radial, the 555rs are junk. I can't get them to hook for shiz. That's my .02
