I wanted to start a thread about how to ride steep, rutted, stony, ledges on mountain roads. I have not done much of this on three wheels. I find that when I am on these roads they always slope away from the mountain and as such I find that when going with the cliff to my left I lower the sidecar with my tilt control and when going with the cliff on the right side, I raise the sidecar so that it is running level. I find that this helps out a lot but still have some problems regarding tire pressure. I am running all tires at maximum cold pressure on the bike because if I do not do this I get excessive wear from time spent on the road. However, when riding on the rougher stuff this high pressure makes all of the tires hard and they tend to bounce off of everything. I think it would be a benefit to lower the tire pressure for all three wheels. I have a car tire on the rear of the bike and on the side car and they are r15/165 tires. I run the bike tire at 42 psi and the sidecar tire at 36 psi. I was thinking that lowering the tire pressure would improve handling and reduce the jarring from hitting these obstacles. I think that this would provide better control but have not done experiments to assess the amount that the pressure needs to be dropped to achieve improved control. I was wondering what experience others have had with tire pressures for these mountainous road conditions?
