I just fitted a pair of maxxis Minion 2.35" tyres to DT Swiss 4.1 rims using rim strips made from Schwalbe 20" tubes.
I gave up at the first attempt as it was too tight, there was no way they were going to go on.
I removed the cloth rim tape and tried again with proper tyre soap and got them both on with a bit of a struggle.
I'm wondering now if I should have used a layer of PVC tape as a rim tape under the rim strip.
Are the tubes going to bulge through the spoke holes and end up chaffing or bursting ?
Does anyone else run with no protection between the rim strip and rim and get away with it ? I'll probably be running them at 40psi if that makes a difference.
