Call AAA (or BMW roadside).
Though there is that goo in a can stuff that you can buy that will inflate and plug your tire on the fly. The downside of that is if your tire blows again it ends up all over your paint and that crap is damn near impossible to get off.
You will not regret getting rid of the RFTs. I ended up with the Pilot Sport A/S because SS were not made in my size...no regrets the ride is so much better.
