After market Tyre Pressure Monitoring Systems

[aitch2]

I see there are a few of these on the market now. Are they any good?

Has anybody got any experience, or recommendations?

[Crow555]

I got one of these based on a review I read on autoexpress if I remember rightly. It seemed (to them) to inflate the tire to the desired pressure more accurately than the rest.

Edit: actually, ignore what I just wrote. You're after something complete different I think.

Check your tyres with a tyre gauge once a week, cheaper, more accurate and less hassle IMHO

This one worked for me..

Thanks smileymikey, but was not asking for advice on how to look after my car.

I am just curious about TPMS, because, living in a warm climate pressure variation due to temperature is considerable, and I would be interested to be able to monitor it.

Trade feedback is that TPMS systems fitted by the manufacturers (which have to be honest, gone through a far more vigorous testing cycle than any after market part)are an absolute pain in the arse. I would recommend close scrutiny as suggested already, perhaps even getting your tyres Nitrogen rather than air filled and be vigilant.

I have the tyresure kit fitted to my Celica. It is great, and I got it cheap as I ran a group buy through the GT4OC.
It gives you individual readouts for each tyre's pressure and temperature so you can see exactly what is going on with each tyre.

Would help you spot slow punctures early, or tracking problems resulting in uneven heating etc

Definitely recommend it, yes you can check with a tyres gauge once a week, but I can check mine anytime I like, from within the car, while I am driving

Most OEM TPMS systems (on non-premium products) don't have sensors in the wheel instead rely on the wheel speed sensors.
They are crap, inaccurate, need recalibrating often, and are only fitted as a cheap way to comply with legislation.

Proper TPMS systems are very good and easy to use.

I have gone the Nitrogen route on my 911, and it has many advantages, especially in that it is not temperature sensitive and that it is totally dry, and not effected by high humidity. The tyres also seem to retain their pressure better, but it can be a pain trying to find Nitrogen when needing a top-up.

Anyway, I am about to fit new tyres, and think I will probably stick with the Nitrogen, but I am tempted to fit a TPMS as well.

OP My suggestion would be go the Nitrogen route....UK price around two pounds a wheel....then check how things go from there!

So you check them but what next? Still got to stop for air.

You need a Hummer. CTIS (central tyre inflation system) lets the driver inflate or deflate tyres while on the move!

[aitch2]

I just want to hear of anyones' experience of after market systems, particularly recommendations for good ones.

I did.

Tyresure system
Recommended!

What else do you want to know about it?

If I could get a CTIS for my Dakota, certainly!

Maybe not for the GT4

Thanks Filski, that is actually the system I have been looking at.

Are BMW a non premium brand now then?

I only ask, as the last time I looked, that's exactly how their system works.

Really? I just did a quick Google search and everyone is talking about the sensors for BMWs being in the tyre valves, which is a proper system.

Maybe the entry level models have the crap version to keep the cost down?

[Superhoop]

I think theirearlier TPMS system used either tyre valve sensors, or the ones that are strapped into the rim - Not sure which

I believe their later system uses wheel speed sensors to detect an increase in rotational wheel speed as the tyre deflates

If you want a failsafe system how about one of these.....

..and getting off your arse and actually checking it yourself instead of relying in an automated system that can fail.

Yup, its foolproof, especially when you are doing 90 mph and you have a rapidly deflating or overheating tyre.- see you in the crash barrier!
