I have been running 28mm Continental Gatorskins and I have never had a flat with the tandem ( about 3000 miles). I know that my luck will not last. I have been on rides with other tandems and 2 times the tire (sidewall) failed and a tire boot would not work and someone had to go back over 20 miles to get a vehicle. I started thinking for the long rides maybeI should carry a folding tire just in case that happens to me, or someone else.

Does anyone have any recommendations for 28mm or a 32mm folding tire?

Is the Vittoria Randonnuer Hyper a folding tire?

Thanks
