On Tuesday morning I phoned The ICE Team and ordered 3 Schwalbe Marathon Plus tyres, They arrived by 9:00AM Wednesday, I have fitted them with no trouble. I am now waiting for the stormy rain to stop so I can go out to play.
I have read on other forums that people were having problems trying to fit them.
Some broke their Tyre levers in the process... I put them on by hand... not wanting to preach to the knowledgeable, but.
I first rubbed a bit of washing up liquid on the tyre beading and also on the inside of the wheel rim, then placing the wheel onto the tyre so that the tyre bead was in the centre well of the wheel, this gave me the extra couple of mil to slip the rest of the tyre on, I then gave the tube a couple of pumps and carefully place it into the tyre so there were no twists.
Same procedure for the outer bead, I think were others have gone wrong is in not putting the bead into the centre of the wheel well.
When the tyre is fully pumped up, you find that the washing liquid allows the tyre bead to properly slide into place on the edge of the wheel rim, not causing the bulge in parts of the tyre.
Due to the slight size increase in the tyre size, I did have to adjust the front mudguards (Ice Q).
Don't forget if you have a trip computer, you may have to recalibrate it's tyre measurements, it could be a couple of centimeters.
I hope this helps.
Bill.
