Question for C'dale road tandem owners
Hello folks, I'm wondering just how big a 700c tire I can get away with on a RT3000. Currently using 32s on the road but am wondering if I can make this bike more dirt road/ rail trail practical. Certainly nothing too technical. Any experience out there?

We ride a Cannondale Tandem it has a E front wheel with 700/50 front tyre that is a touch to big but at 40PSI max is great
The rear is a 700/40mm and still has clearance but does rub after mud it also runs at 40PSI
so with a sprung stoker seat post giving 50mm for bumps we have a great ride
I'm 73 and Kathy 74 witha bugered left ankle hence the front motor

I think the rule is to have at least 5mm to 7mm clearance all around your tire. What do you see? You are probably close to that with the 32's and 35's might be as good as it gets, but I don't know that. These days people are throwing the clearance rules out the window. Are you trying to stay with 700C to avoid the cost of new wheels? Because going to 650B allows for bigger tires assuming you also have disc brakes.

Without the E front tandem riding would no longer be posible as can't avoid the hills and Kathy can't walk far.
A fellow tandem rider in our group fitted 650 rims and runs wide tyres and can run any pressure he wants with comfort the decider on gravel .
They have done many overseas trips taking their tandem on trains and planes
Our Cannondale had 700/38 front and 700/40 rear and never had a problem
sp good luck and enjoy the ride

We have a 2004 and run 38mm Soma Supple Vitesse tires. The front is tight at the fork crown, so we are maxed out. Works out great for us as we are almost always on pavement.
I highly recommend the tires (EX version). We got over 2500 from our first pair with one flat - pretty great for 320g tires.

Thank you all for your advice. Now have to start watching for sales!

A bit late to the party, but I upgraded us to a 650b wheel-set as we prefer gravel riding. This has allowed us to go up to a 50mm tire front and rear. A massive improvement in experience both from tire options, and from a vibration damping / ride improvement.
*edit* didn't catch that you're running with canti's, so that makes the swap a bit harder but not impossible, they do make long-reach leavers which would work with 650's.*
