I’ve always gone for the reasonably priced 26″ Schwalbe tyres. Marathon Green Guard were my normal all round choice for almost puncture free riding, but they are heavy, not Marathon Plus weight, but not light either. (see link below for comparison). The standard Marathon Kevlar (old) tyres were lighter but weren’t robust enough for my needs.
Years pass, and a more expensive tyre catches my eye, the Marathon Supreme and coming in around 440g it’s a good weight saving:
I’ve never had a folding tyre before, they look very wonky to begin with, but look good once fitted:
Because I had an old Marathon Plus on the rear, it’s reduced the weight by around 750g! I just hope they don’t yield punctures, the reviews are very positive, but only time will tell whether they are worth double the money!
That site shows the weight saving and fractional rolling benefits too, but also less puncture resistance.
