I have been using an old Marin Muirhead 1993 MTB for the last 25 years, pottering around on cycle routes and riverbanks mainly. Zero punctures. As a result I haven't had to fix one since I was a kid and wouldn't have a clue what to do. I went on a 30km ride with a cycle club last year and 3 of them got punctures - I was astonished.
Whatever tyre I put on is likely to be more comfortable and have less roll-resistance than those on my 1993 Marin - I just want one that definitely isn't going to strand me 50 miles from home...
