Puncture repair patch kits..........

Any theories as to why wider tyres means less flats ?

Tire pressure is lower for wider tyres, so there is less impact force when you hit something sharp. Also you are less likely to get pinch flats on wider tires from blunt objects as you have a larger surface area.

I used to use Marathon Pluses on a commuting bike, but switched to Marathon Supremes when they were released

I'd be interested to know the longevity of these tires. I weight 95kg and use panniers when commuting. So far I've done over 4000km and I reckon there's a good few thousand left in the rear tyre. The front still looks virtually brand new.

+1 especially at nearly double the price of the marathon plus.
