I don't have TireMinder, but TST, but I bet they are similar. Sensors stay on the tires throughout the travel season. They are sending their signal whether the wheels are turning or not. I do remove them over the winter, as that turns off the transmitters. Just had to replace some of the batteries this season - they had been in there for almost 3 years. So for me I doubt I would remove them for your 3 month period, but no harm if you did. Do make sure you have LABELLED each sensor as to which wheel it goes to, otherwise if you put them back on different wheels your readings will be wrong! ST
