I tour on a Waterford Adventurecycle. It is a fabulous touring bike.
Replace tire or wait?
I ordered a new Schwalbe Marathon Plus for my back tire. I had a week to wait until it was delivered.
In the meantime, I took a ride and noticed a thumping coming from the rear tire. On further inspection, I saw a round hole in the tire. The only reason the tube was still good was the tube saver that I inserted between the tire and the tube.
I was too far away from home to trust that the tire would hold. However, I happen to be across the street from the REI store in Corte Madera, I happen to have $20 on the bike, and REI happen to have a cheap tire that I could buy. The only bad part was that it was a 700x32cc tire and I normally use a 700x28cc tire.
Two days after that ride, I picked up my Schwalbe tire (700x28).
My question is this: Should I keep the cheap 700x32 tire on the bike and replace it when it wears out or should I switch over to the Schwalbe now and keep the cheap 700x32 tire in reserve?
For what it is worth, I don't plan any touring until May, 2007.
Higher pressures mean lower comfort, in my experience. Wider and lower pressure than the 28 probably mean nice ride with virtually no sacrifice in rolling resistance.
It really is up to you. You can keep the cheap tyre on there, and it will wear out, probably fairly quickly, then replace it with the new Schwalbe. Use the Schwalbe now, and you might have a few doubts in your mind about its longevity when you get to touring next May. I'd probably favour keeping what's on there. It's served you well so far
