It’s not a good day when you have to drive on a run-flat ring. So, minimise risk by ensuring the tyres fitted are up to the job.
Some basic knowledge of reading sidewall markings is important, as this gives the load and pressure limitations of the tyres. For example, take the 200 series Toyota Land Cruiser soft skin platform; the tyres fitted as standard have max pressure issues. Generally from 35 to 45 psi. This is not good enough for the modified vehicle, which may have a recommended tyre pressure between 60 and 70 psi.
The load rating may be ok, but why compromise on safety? It would be better to fit a tyre designed to hold up under harsh road conditions, especially if you have to respond to the worst-case situation.
Even in areas with good roads and networks, you still need the surety that the tyre will keep integrity if you need to jump the kerb.
Most AV companies do take this into consideration and fit some marvellous pieces of rubber which can deal with loads of issues. Some don’t.
To conclude. Know the tyre limits and capabilities.
Ensure tyres are at the correct pressure before you roll – and that you have the ability to quickly identify if the tyre is losing pressure whilst out on a mission. There are some excellent tyre pressure monitoring systems in the market place.
Mind you; the new 200 series does have that system built-in now. So, ensure that the company which does the armouring mods and upgrades also resets the limits for the system.
Otherwise, that orange tyre will be on the dashboard all the time, therefore, making the heads up system useless.
