The current tyres are Schwalbe Lugano 700 23c and I use the bike for 20-30 mile recreational rides on country roads, many of them in a poor state of repair. I'd like to put something a little heavier on, so that I am not constantly forced out into the middle of the road by the more minor potholes and botched road repairs. I weigh 10 stone. What sort of tyre size should I look for, and can you recommend a specific tyre?
I killed an Ultremo ZX in 2 rides but the gatorskins have done about 1500 miles with not so much as a few small cuts which I glue.
