Aside from a big A on the sidewall and a bit more rain friendly tread compound, not much. They seem to last a bit longer too. They're being discontinued though, so my next set won't be re11's lol. The re71 is pretty much covering the kick ass mega grippy tire category for Bridgestone, followed by the s04 then the re50/97/970 and if you still care about them the 760's
