Exactly. I pay special attention to those who have used multiple products throughout years of being an enthusiast. And these sites are good for identifying trends as well.
My main point on retreads is we're now talking about safety. Its not "are they loud?", "how long do they last?" , etc type of questions..... its "are they truly safe for daily driven highway use with my kids in the back seat" type of question that honestly makes the $300 savings a moot point (IMO). And that's why I don't run them.
Hell, you notice that most guys will spend $300 on new rotors for their vehicles instead of resurfacing rotors with plenty of meat left.... I wonder if there's anyone who would run retreads to save $300 but is also against rotor resurfacing (which isn't an issue when done right). That would be kind of funny.
Edit: hence, in my personal opinion, I think retreads have a solid place in the market for trails rigs where the risks/consequences are much much lower.
I know there are at least a few in the XK/WK community running them on DDs, so I expect we'll hear some differing opinions. It definitely comes down to a personal choice in this matter.
