We are also about a 290 pound team. We've used mostly Conti Gatorskin 28s on the tandems we've ridden and liked them fine -- no problems. Our new Burley came with Pasela 28s and they were also fine, although maybe not as long wearing as the Gatorskins. I am thinking of putting on some Michelin axial or pro race 25s for the Davis Double this weekend, just to give us a little better performance and feel for the road. If it seems to make enough difference, I am thinking it might be worth running high-end 25s or even 23s in longer or more competitive events, then switching back to the long wearing Conti 28s for training and riding around town.

Any thoughts from the experts?
