Just wondering if I should disengage my friction drive when I'm not going to be riding it for a few days. I'm wondering if any stress may be induced to the tire at the point where the drive roller is pressing down firmly enough to easily see the depression in the tire under the roller. I don't push it down with all of my might but pretty firm as it never seems to slip at all.
Tire is about 14 months old with 1000 miles, 500 pedal miles and 500 motor assisted miles (25 mph) rated for 87 max psi, I have them at about 70 -75 psi
