I replaced the Kendas on my DT IX FS after about 1,000 miles - they had plenty of tread left but I was getting punctures on a regular basis, which is no fun to repair in the dark, cold and wet winter mornings. Plus, I would miss the train and get to work with filthy hands.

So I got some Schwalbe Marathon Plus tyres and haven't had a single puncture since. They certainly are heavier than the Kenda's but they feel like they roll better. I inspect them every day and pick out the occasional chunk of broken glass. Highly Reccomended IMHO.

I found getting the Kendas on and off the rim easy enough, but the Schwalbes were a bit tricky.

My tip is to lube the rim and/or the bead of the tyre - water (or spit for those roadside repairs) works ok, but a blob of liquid soap works wonders!

All the best,
