If you want replace them proactively, I would say 100k miles would be good time because I do see horror stories on hose bursting on e46fanatics.
Having said that, at 100k, if you don't have previous maintenance records, I would do whole cooling system refresh including water pump, thermostat, expansion tank, hoses.
