I ran Michelin Axial Sports 700x23 on a recent tour of the Hebridean islands, suffered many punctures - all on the rear, the increased weight of the slick increased the surface area of the tyre on the ground, riding over anything (sharp stone, puddle and anything sharpish), I would hear a fluctuation of air, then that dreaded thud thud thud, brakes on, off bike and straight onto the quick release.
So when I got back, I ordered a pair of Schwalbe Marathon 700x25 for £30 a pair from
Ebay seller Highonbikes. I opted against the Plus's as they weigh that little bit more. Fitting them onto the bike, which is a learned skill really, so far they have been brilliant, confidence has been restored in my bike.
