There are a couple of givens with respect to tire pressure that are true for sidecars as well as four wheeled vehicles. It can be interesting and usefull to experiment to see the effects tire pressures have. I use tire pressures to noticeably adjust the handling characteristics of my sidecars. It will be difficult to perceive much difference in one or two lbs. Lowering pressure between normal and 10 lbs less as an experiment should be noticeable. Lower tire pressure than normal in the front will cause a vehicle to steer heavy and under steer. Lower rear tire pressure will induce oversteer. Obviously there are safe high and low limits that should be observed. Higher tire pressure can also afford less traction and lower tire pressure can afford more traction. It's all a matter of tradeoffs but it's something worthy of understanding and experimenting with.
