i have a tandem and have had since 1995 rotated once a year before fishing started and i am 2 years on my 2nd set but if you dont rotate fronts will wear out fast .they get the most scoot on a sharp turn. but as far as ride and pull i wont own nothing but a tandem.example flats-single you are going to stop. tandem if for some reason no air in spare you could limp to a gas station a house or something to get air in spare hope this helps and just my 2 cents
