I do have an LSD diff ton maximize traction in winter conditions. Those tires grip really good in deep snow but i was expecting better on ice... I've used them at the begening of november and i've saw a little bit of treadwear after a mouth of smooth driving in dry conditions. At the price of aech tires i would love them to last a little bit longer. Those tires are silent at 50KM/H but start to make noise at 80KM/H ( my alignement is ok so it's no the problem).
Excellent tires! Much better than the tires that were on the car when I bought it. The non OEM size is also better suited to the type of car this is and should have been an optional size at the time. They have excellent traction off the line with minimal spinning under normal driving. They have also greatly reduced the fishtailing and squirreliness that came with the previous tires. As a bonus they look cool and provide the performance expected of a muscle car.
Good dry performance. Pretty sticky. Fairly predictable. Merely ok in the wet. Can stop faster than standard breaks with stock pads allow. Ok lets get this straight. These tires are loud. It is hard to talk on a phone at highway speeds. I drove across country and it was annoying but tolerable. Caution! These tires are useless in the snow. Do not attempt to drive on ice/snow in a rear wheel drive with these. Not a joke I got caught in the beginning of a snow storm and had to literally skate down the highway turn off and pulled into a gas station sideways. 5 mins later I could not back out of the station. Saw crappy fwd cars having little trouble but my stang was useless. The next day I saw savage wrecks along the highway. Skill, luck and traction control kept me safe. Good grip and wear. A good bang for your buck fair weather tire but I doubt I will rescue my Stang with these.
Replaced the stock 16" wheels with 17" pony wheels. I researched hi-performance all season tires and settled on these. I was thoroughly impressed with their performance. They handle the rain well, the car felt much more stable in wet weather than before. Snow performance was very good. I've driven mustangs year round for many years so driving in winter is important. I also commute 70 miles a day so I spend quality time in my car. These needed replaced after about 45,000 miles and I fell into a deal for factory 18" wheels with brand new Yokohama Avid ENVigor 235/50R18s. I'm not happy with the Yokohamas, They spin too easily in wet weather and I have little confidence in their stability when driving in wet weather. The Zeon RS3-A tires are a much better tire. When the Yokohamas wear out I'll be putting another set of Coopers on the car.
I am on my 3rd set of NT555's, my '06 Mustang GT has 107,000 miles on it. First set lasted about 36,000, second set made it to 40,000. Great tire, I'll always buy them. A little pricey so you have to shop around to get a good deal, but well worth it in the end.
