For those of us that use our 4WD's off-road on a regular basis external TPMS sensors are an absolute PITA because we are forever changing our tyre pressures, internal sensors make much better sense[thumbsupbig]

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

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.Quote:

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.Quote:

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.Quote:

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.Quote:

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.

Does it just stick on to the windscreen?
