The tyres of cars parked in two St Helier car parks are being checked by staff from DVS and I&E.
Scanners are being used to measure tread, and DVS, Infrastructure and TAF Tyres staff will be giving advice.
They're at Les Jardins car park today (7 October) and Patriotic Street multistorey tomorrow (8 October)
Any motorists can also visit for a free check .
No penalties will be issued for worn tyres.
Infrastructure Minister Constable Andy Jehan says it will help the government gather data on tyre condition.
“This is a great opportunity for commuters to get their tyres checked, for free, while also supporting us in gathering some data on the condition of tyres on our roads.
“Driving a vehicle comes with responsibilities, and the general advice is that tyres should be checked once a month or before a long journey.
"Unfortunately, I’m sure many Islanders are not getting them checked regularly enough, resulting in some potentially dangerous vehicles on our roads. This initiative is all about increasing awareness on tyre safety and ultimately ensuring vehicle owners are informed and safe on the roads.”
The checks will be at Patriotic Street on Tuesday 8 October.
Staff are being trained by UK charity TyreSafe, and Translogik to use the scanners. Stuart Lovatt is Chair of TyreSafe:
"TyreSafe is delighted to be working with the Jersey Government to help raise awareness of the importance of tyre safety on the island. This partnership aligns perfectly with our mission to raise awareness of tyre safety.
"Together, we can make a real difference by reducing tyre-related incidents and ensuring that drivers are equipped with the knowledge they need to keep themselves and others safe on the road."
