I have the Nitto Invos on my car. I first had 275/30/20 and 345/25/20. But now have the 285/30/20 instead of the 275s.
I have no complaints so far. They are a softer compound and have great grip. I have driven them in the rain and find no real compromises. They are pretty quiet despite their widths and size. I cannot attest to their wear as they have not been on the car long enough to see any noticeable or abnormal wear.
I would recommended them as a definite choice. I would go 275 and 305 over the 255.
Although I haven't had any of the issues Chris spoke to in his prior post.
