Thread: external TPMS for D4

Isn’t removing a sensor no different to removing a standard valve cap??

I’m about to fit my external sensors, but found a system that doesn’t require the user to adjust the set pressures each time there is a change in Tyre pressure.

Which internal sensors do you run?

I don't use a TPMS system at the moment But if I do decide to fit one I would go with the internal sensors.
I don't use the valve caps because I can't be bothered taking them off and putting them back on every time I have to air up or down and external sensors would create the same problem for me.

Not using dust caps especially when 4wding in not very wise. If its wet then mud will accumulate around the vavle stem and next time you air up or down, the particles of dirt will no doubt end up in the tyre or start to destroy the valve seal. Then ylu will have a slow leak etc. I originally had internal but when one was destroyed by a tyre fitter, I went the external route.

Yeah. Not using valve caps is the best way to get a dirt-based slow leak in the valve stem - the last thing I’d want when out in the middle of nowhere.

I have run around the Bush and on minesites without valve caps for decades and haven't had any real dramas with valve failure, Most of my tyre problems have been caused by sharp stones and stakes.
IF I do have a problem with a defective valve I simply change it out for a new one,No big deal.

I off-road regularly.The PITA is airing up and down. For me, a couple of seconds to undo and redo a dust cap is nothing.

An external sensor is much easier to replace if it fails than an internal sensor.

Safe T tyre from safety Dave is good..had mine for 4 years on RRS and caravan. Have wired it in under the dash.
He also can supply a booster for the caravan sensors.

I ended up buying this one on eBay: Solar Wireless LCD Screen Car TPMS Tire Pressure Monitoring System with 4 Sensor | eBay.

Safety Dave was a bit rich, and needed to monitor only 4 wheels. For $37.39, my wife has nicknamed ours Safety Da-Wei.

Solar powered with usb power-in option. The user can adjust the settings for the high and low pressure warning.

I have installed I but not taken out on the road yet. Based on my pre-installation tyre pressure check (with digital and pencil gauge), the TPMS is 1–1.5 psi under for 3 of the tyres and 2.5 under for front-left. As long as it is consistent, I can live with an initial calibration issue. The real test will be what it reads once the tyres have warmed up and does it keep a consistent under-reading.

I will report back.
