Our Tyresure tyre pressure monitoring system has failed. It has come to light that after around 12 months use via thermal heat transfer within the tyre the transmitter valve units crack and stops working (it has become a known manufacturing fault). Image attached for reference. We are trying to get a replacement set under warranty, but unfortunately for us our system is 18 months old. Be warned all those considering, enquire first to see if they have upgraded the product to overcome this issue! Having said all this the product does work well, when its not overheating 🙂
