Anyone got a set of these fitted looking at purchasing a set for car & caravan note there are 2 types those that replace valve caps and a in the wheel type not sure which type to go for or the signal range when fitted to van. :-\ :-\
-
they are expensive and can easily break down..

Stop the press :o
Cem is correct... no substitute for regular checking with a known gauge :y
-
Considered them, but haven't dived in due to cost, breakages during tyre changes, and issues programming after tyre changes.
Having had a sudden tyre deflation, I see a need for something, but cost and reliability put me off tbh.
But at a steady 50 though, necessary? Really?
-
looked into cost so expensive or not isnt a issue they also monitor tyre temperature so really want them to be for warned for peace of mind when towing long distance down to South West or France .Going down to Vendee last year checked tyres at Dunkirk off ferry within 200K (approx 2hrs driving)o/side van tyre had gone down from 50psi to 35psi( knackered valve) if monitors were fitted sure the would have indicated this and I am sure none of us check out tyres every 2 hrs.

True. If there was a reliable answer....

If your towing or driving summat big, you should be doing a walkround every time you stop ::)
15psi would show on a loaded tyre, especially a caravan sized one :-\

Agreed with above thats when the issue became apparent, realy looking for feedback from someone with history of using these not some general opinion a trailer blow out even at 50mph can cause mayhem.http://www.tp2-towing.co.uk/wp-content/uploads/2012/02/caravan_crash1.jpg and stragely enough losing 15psi gave no feedback through steering on French autoroute!!

Agreed, but when doing 2 hour stints it is not possible to continually check.
The ONLY 'van tyre problem I've ever had (touches wood) actually occured on leaving a motorway service area. During the stop the tyres and the wheel bolt torques were both checked as this was the first long run after a service, so I know that all was good. Onto the motorway and 5 miles down the road we come to a halt in traffic, due to an incident ahead. Some stop/start crawling for 10 minutes then a complete halt as the motorway was closed for the air ambulance. Engines were switched off and folks got out to stretch legs. At which point it was noticed that one tyre on the van was pretty soft, and going down. One wheel change later and the nail in the tyre was obvious.
If we had not been stopped for the incident it could have been a very serious problem at 60 mph .... a TPMS "might" have warned me in time ... who knows ??
I have often thought about TPMS since then, but the lack of reliability has put me off. I certainly believe that a reliable, easy to use TPMS would be a major safety addition... but the numerous web reports about failures is not prompting me to purchase at the moment .. :(

Yea thats what scares the crap out of you,you were lucky but seen a accident on M5 couple of years ago in which the van ended up as a flatbed trailer spewing debris far and wide

Run flats any use :-\
-
Ok, so you have tpms and your doing 50 with a pikey palace. The tyre blows out. Instant flat. How does tpms help?
A slower deflation then yes. See, I think there is more credit being applied to tpms than is reasonable.
I'd use it as a day to day check for performance reasons. I'd be intrigued to see the pressure differences over a cold morning start followed by a run down the motorway at 5am. That sort of thing, if its accurate enough of course.
But the Holy grail against all eventualities...? Nah, don't think so. In conjunction with run flats maybe, but that's mega bucks and brings in other nuisances like ride quality and cracked rims and.... Tram lining. ::)
Edit, Al beat me to it. ;)

as usual :) ;D
-

yes you can fit Tyron bands to keep the deflated tyre on the rim but most places near my local dont have the facilities to change tyres with these fitted but seeing as my tyres will require changing due to age later in year may be a option then
-
What size are the tyres :-\
-
175x13 C, 97 +standard 16" Cd wheels on car

It doesn't ... it cannot do anything about an instantaneous blow out.
However, the majority of research appears to indicate that an instantaneous blowout is an extremely rare occurrence, most deflations start somewhat slowly, and then get worse quickly, often then as a blowout as the tyre overheats due to running soft (in a soft tyre the plys actually rub against each other as they pass the "bump" at the bottom every rotation, this friction leads to a rapid heat build up then structual failure), so TPMS "may" give some warning that this is happening either by pressure drop, or by temperature rise.
The main problem with the "pikey palace" scenario is twofold ..
1) The tyres are usually carrying a higher load than a car .. eg, my 'van is 1600 kgs on 2 tyres .... thats 800Kg/tyre. the car is 2200 kg on 4 tyres . thats 550kg / tyre .. a large load differential so when things go wrong the do so faster.
2) Lack of "feel" ... experienced drivers like yourself can instantly tell if a car tyre is "soft" as the car "feels" different, if front the steering is "just not right" .. if rear it just "feels" wrong through the seat of the pants... this doesn't happen with a trailer of any description, there is no "feel" at all .. so a soft tyre on a 'van just keeps getings worse and you just don't know it...
TPMS has the ability to inform the driver of the state of the trailer wheels in pressure and temperature ... but the reliabilty is still, IMHO, too suspect.... if it doesn't tell the truth all the time .. it may well not provide the very information it is designed to ....
-
The TPMS setups are actually pretty reliable these days (unless it has a Renault badge!) and if they include temp sensing then all the better.
Reality is that a blowout is normally caused due to heating of the tyre wall due to a slightly flat tyre
-
lets look at what can cause a instantanious blow out among the reasons I see are under inflation poor maintanance .incorrect type for purpous, poor tyre construction, belive (Firestone had this problem in USA a few years back) catastrophic damage caused by large foreign objects theres nothing you can do about the latter two but if you take steps correcting the others then you will vastly reduce the chances of said blowout (god this is turning into a tyre thread) also read in Auto Express TPMS will become compulsory on all new cars soon.

I'm guessing you refer to OEM as fitted to new cars ... the aftermarket add-ons for older cars / caravans seem to have some serious reliability problems from the reading I've done ... :(

My research indicates the "downside" of those internal types are :
Tyre needs to be removed/refitted to fit .. and change batteries/service if a a fault develops. Most tyre fitters will "try" and tell you you cannot refit as they always change the valve (not true you service the unit itself). Easily damaged by said stupid tyre fitter. Large weight requires offsetting by accurate balancing, but that will be another large weight somewhere else on the rim. Can suffer from a poor signal due to screening effect of the tyre .....
"upsides" .. secure.
Other type is http://www.tyrepal.co.uk
"Downside" more stealable, possibly less accurate, appear to be be less robust.
"upsides" - Light so no balance problems. Easily moved from wheel to wheel. No difficulty changing tyres. Battery easily changed.
TBH, it is the tyrepal "type" that I'm looking at, but they do sem prone to problems... ok .. the manufacturers have a good reputation for sorting out problems ... but if the problem results in no warning when one is needed ....... :(
-
I think they are a good idea for towing. Having had a tyre failure on a twin axle trailer (slowish deflation - picked up a nail in roadworks) when towing, you rarely get any clue that anything's wrong, and if it saves a sudden failure later.... :y

Think I have made my mind up to purchase a set and become the Guine pig on here, probably the valve replacement type as the in wheel type seem a pita as Entwood sez if any problems + only lookin to fit for long distance journeys/towing so can easily remove when not required now just researching the most reliable type & contacting said manufacturer regarding extending the system as most seem to come with 4 sensors should be able to get a system for approx £200 and its me burfday soon so anyone wanna buy me a prezzie knows whats on the shopping list :P :P

I notice they do a can-bus system, as the Insignia has tyre pressure monitors, I wonder if the caravan could be added to the system.

Is the insignia on run flats AA?

I'm now on my 2nd car with factory fit TPMS and have to say it is vey good.
The only real issues I had previously is the sensors only last 7-10 years so I was getting an 'odd' failure. Occasionally it would say sudden loss of pressure to nearside front, but after few yards would be fine again. New sensors solved the problem.
If you use run flats you HAVE to have TPMS fitted. Tyre place should refuse to fit unless you do as its very difficult to tell (on a car anyway) if the tyre has lost considerable pressure
-
Yes brother in law has tpms and run flats on his Beemer(Spit).
Didn't understand the true meaning of the dash warning, and as the car drove ok he continued on his way across Europe. Until the tyre eventually disintegrated of course.
Oh sigh....
Having driven the car though, if you think omegas feed back through the steering a lot, try run flats. Horrid. :(
-
I know a chap who had a 530d tourer... he had a pressure warning come up which he ignored, and on the way back from Heathrow one day felt a bit of a shimmy as he joined the M25. Two days later got the tyre checked and found two inches of tread missding from the inside edge :o
Apparently no change to the cars behaviour :-\

If the Insignia sensors transmit @ 433Mgz then possibly yes they also do a serial data node to integrate sensors into your present monitor interface.

Nope.
