Worth it do you think?

The only serious problem I have had with a puncture, the front wheel went flat almost immediately. I was doing 70 in the outside lane of a dual carriageway, overtaking a big truck.

Don't know which of us got the biggest fright, the truck driver or me.

Managed to hold it upright down to about 30, and into the grass verge.

But I don't think any TPMS would have made any difference.

For the front is particular, TPMS could certainly have advantages, though you don't need to have constant indication of the actual pressure.

On ABS equipped bikes, you can have a system which tells you when one wheel suddenly starts turning faster, indicating one tyre is low in pressure. Many cars are now equipped with this method.

But with any type, all you need to know is that the pressure has dropped a certain amount from the preset.

The possible downside to having TPMS is that some assume they will be told when they need to check tyres, and don't check at all otherwise.

Heard a story on a car foum, someone complaining that his dealer refused to replace a tyre which had damage because he had never actually checked tyre pressures in the time he had owned the car. He assumed with TPMS he didn't need to. But the system was based on ABS so only tells you one wheel has a problem. If all tyres lose pressure - as they do over time, the system won't alert you.
