tyre pressure monitors - good idea? what brand is the best to get!

David l1. Do not agree. I have had Sensa internal tyre monitors for over 15 years and they have always been extremely accurate for both pressure and temperature. You get what you pay for.

Only internal tpms sensors can give an accurate temp, but my Masten externals from Digoptions agree with my pressure gauge +/- 1 psi.

Warren H. Temp is not pressure. If you want to know the temperature inside the tyre the device reading the temperature has to also be inside the tyre, simple logic. Knowing the temperature inside the tyre is more important than knowing the pressure. The internal temperature is affected by the air pressure AND the weight on the wheel, AND the speed being driven, AND ambient temperature, AND the road surface. Keeping your tyre temperatures under 60 degrees Celsius will go a very long way in ensuring you do not have tyre problems.

I concur with Robert, my experience is exactly the same.

I gave up on the locking devices for the same reason, Barry. So far, none knocked off and airing up/down is much less fiddly.

I bought a cheap open ended spanner that fits the lock nut and simply bent it (a lot) to make the undoing of the lock nut very easy and simple... The pissy little spanner supplied was thrown in the bin.

If you do choose external sensors, and doing a lot of track / sand work, it's almost imperative a 2nd set of valves are fitted.
I did this on my 8 Ranger rims (4 + 2 spares + 2 for camper), opposite side of rim to std valves.

Also, get the shortest valve stems you can, as it limits movement from coro roads, vibrations . . . I hada couple of valve stems get damaged due to desert tracks / outback roads when normal ones were fitted.

Digoptions have 8 monitor systems around $500 or so when I bought, to be honest I have also had a cheaper ebay unit with 4 for town car, solar on dash, works as good, think it was under $40.
2 of these one for car one for towed vehicle would be ok . . . the important thing is having something that does the simple job of telling you if you have a slow leak, stop damage occurring by setting the alarms to whatever level you like.

I just found the ones I bought . . . Now $434

Edit - 2nd set of valves are of course for air down / up easily, the TPMS monitors stay on permanently.

Barry P, or buy the "T" valve stems.

I removed the locknuts as they are a right royal PITA. I’ve done a lot of kms without the locknuts and haven’t lost one yet.

T-valves don't fit all rims. I was asking on the Pajero forum about any experiences with them and was reminded that the Pajero has a recessed hole for the valve stem and they can't be fitted, so check before you buy if you have alloy rims.

I've been using the Safety Dave system and T-pieces for about 4 years now. No problems with either.

I have same setup for a couple of years now, warnings have included - inadvertently left the van park brake on and the temp warning alerted me, staked inside of van tyre and warning (rate of deflation)allowed me to find a safe place to pull over and change. Often wonder how many van roll overs could be avoided with TPMS, especially with dual axles.

Hi WBS,
I'm considering to buy Safety Dave system. Just wondering, if you are still happy with yours. Would you recommend it?
