Mrs Greenroofer has a Giant Expression N7 utility bike like this. With its roller brakes and hub gear it's pretty much maintenance-free, but you really don't want to have to take the wheels off. The tyres it came with are odd knobbly things, 700c x 40, I'd guess. They are wearing out and we've started getting punctures.
Given that I have to fix the punctures, I'd like to consult the CCE hive mind on alternative tyres. We need puncture-proofness and good cushioning because Mrs G is very sensitive to jolts and jarring from the road. This is a bike for the road, so we don't need knobbles at all.
I'm thinking something wide, smooth(ish) and puncture proof.
My ideas are:
1) 38mm Marathon Plus
2) erm, I don't know what next. I was going to say a 'Big Apple' but I find they are only available for 26" wheels.
So, what would you advise?
