    Default TPMS - Temperature Setting

    What is the correct / safe setting for tyre temperatures on a TPMS? I've tried to find a safe tyre operating temperature value on the net, but no luck.

    On our December trip my caravan tyres gave an alarm on the Carnavon / Vosburg road. Temps where 71˚C! Vehicle was running at 65 on front wheels and 69 on back wheels. Unit alarm set at 70˚C on all axles.

    Don't think there was an issue there, but would like to get the correct setting on the unit.

    Thanks

    Leave it as it is. 70 is a safe bet. 5 or so degrees will not be an issue, but the alarm will ensure that you keep an eye on it. Just stop if it goes to much higher, also check the pressure. It may be way too low.

    A lot of people deflate their tyres when going onto a dirt road, but do not realise if you drop to say about 1.6 bar, you must lower your speed accordingly, and not exceed 80, maybe even 70 kph. Low pressure and speed lead to overheating, and that is what causes tyre failure, very quickly.

    If you set it to say 80 degrees, by the time you get a warning of it going over that setting, it may already have damaged the tyre

    The default setting on my TPMS system is 70 C so I would leave it at 70

    OK, thanks. Going to leave it at 70 for the next trip. It was only on this particular stretch where it came on and I was in a bit of a hurry to make the gate at Mokala!

    I set it on 60. Just to have an early warning, but so far never had a temperature warning. With a slow puncture you usually get a pressure warning long before it reach those temperatures.
