Tire pressure monitoring systems

You can change the batteries on the TST Model 507 (not the model 510). The downside with the flow thru sensors are they are physically larger. If install correctly and not over-tighten, the standard sensors do not leak so you don't need to remove them too often. The only time I remove the sensors is when I experience extreme ambient temperature changes (winter to summer) and when I put the rig to bed for the winter. I have also found them to all be within 2 psig of my calibrated tire pressure gauge, but as identified above, your real concern should be any significant changes in pressure and/or temperature. They are probably most important on the toad, because a flat back there will not even be noticed in the MOHO until you are creating sparks from the car dragging on the payment.
