Anyways, Schwalbe Marathons (any level) come on just about any decent IGH-based German bike as people never want to take the rear wheel off. They're quite good for puncture resistance.

I bought one Schwalbe Marathon Original in 23-622 as I was tyred (hahaha) of getting flats and having tyres (not tubes) blow out. They were on sale for £15 each, so how could I say no!

I guess I live in the ghetto as shown by other photos (highest concentration of pubs in Britain ... 181 on the island of slightly over 10mi2), so they're a ton of glass always on the street (no deposit in the UK or residential kerbside recycling for glass) thus a ton of bottles end up broken on the streets.

I had a flat recently (the first since I installed the Schwalbe Marathon Original about 1000 miles ago) and when changing the tube, I had about 3 extreme cuts down to the green guard that probably would've destroyed most other tyres. I'm not so excited about the treadwear, but I think that the British roads are much tougher than anywhere else. I do a fair bit of riding on bricks, for example. As we don't get smooth asphalt like you have in the states.

I have attached a photo of the one that lead to a blow out.
