I have had a flat in my rear Mich Mud each of the last 6 times I have been out on the bike (last yesterday evening on a light sandy/soil trail).

Can anyone beat that for a useless tyre?

I'd check to see if the rim strip in your rim has moved, exposing spoke holes or forcing the sharp edge of the valve hole against your tube valve. If it has happened so many times, then I'm almost certain it isn't the tire.

It's either an exposed spoke hole or something sharp stuck in your tire casing. To check for the latter, lightly drag a tissue over the inside of your tire. It will snag on whatever's protruding.

For crying out loud muncher - how could you flat 6 consecutive times and not check to see if there was something sharp in there?

Another question is how high are you inflating the tire. The Michelin's max is 70 psi; it's sometimes tempting, and probably foolhardy, to go well beyond that.

You should be able to tell when repairing what the source of the problem is, and from there figure out what is going on. Is it a snake bite?

I had two blow outs on the same wheel in less than 1/4 mile. It was a brand new wheel with stock rim strips (Mavic Cosmos). I replaced the rim strips and have not had a flat since (400+ miles).

If the problem is the valve hole -- the rim strip has moved, pinching the base of the valve against the exposed edge of a valve hole -- a n effective on-site fix is to put a piece of electrical tape over the hole and then poke the valve of the new tube through. The tape creates a kind of sleeve around the base of the valve that will protect it from the sharp edge of the hole until you can get home and replace the rim strip.

Electrical tape: the cyclist's greatest friend.

Looks like you've already gotten some very good advice from the other guys, but I wouldn't leave the house without your patchkit and a pump if I were you :)
Nope - it's the tyre...muncher

Found the cause each time - tiny shard of metal once (fair one) - all the other times small thorns or other bits of organic rubbish or exactly the kind that you expect to find on most rides. I run them at around 65 so not a pressure problem. They are just not made of very resistant rubber, as can been seen by the very fast wear rate if you ride them on the road for any length of time.

The thing that gets me is the price they charge for them!

MJ was also moaning a while back about how bad the Sprints were for the same reason - you just get *lat after *lat..
