i have found this not to be the case in nearly 100% of tires i've dealt with. sometimes easier to install because it holds the round shape a bit better but a kevlar bead almost always holds better once installed. the bigger issue though is weight, and wire bead tires generally have low tpi and crummier compounds.scottzg said:Folding tend to be lighter, wire tend to hold the rim a bit better. More importantly, wire is often used as a cost cutting measure, so they also indicate lower tpi casings and hard single compound rubber. For heavy duty tires this isn't the case though. The folding vert is better.
