Does anyone out there have any experience of wireless tyre pressure
monitoring devices - the sort which have special valves containing a sensor,
and a central display with LEDs and a bleeper and report status?

Yesterday, I wrote off an otherwise perfectly good 225/45x17 tyre because I
had apparently been driving it flat for a while without noticing.

In days of yore I could always tell by the seat of my pants if a tyre was a
bit flat. But many modern cars are grossly over-tyred, with very wide low
profile tyres which *look* flat when they're not, and don't really *feel*
any different when they are.

At £100 a throw, you don't have to write off too many tyres before a
monitoring system would be cheaper.

Any comments or recommendations?

TIA.

How about manuall checking your tyre pressures weekly, at the same time as
you make all your other routine checks?

You do make routine checks don't you?

Must be "very" low profile if you can't tell the difference when it's
flat .

Depends on the car, a flat at the rear of a 'proper' Citroën with LHM
suspension is really quite difficult to detect unless/until you take
some corners fast.

Yes, when I had a flat on my Xantia, on the motorway at maybe slightly more
than 70, I didn't notice until I smelt burning rubber :-) I'm old enough to
remember the Citroen GS ad where they blew a tyre out when it was in between
two trucks at speed :-)

That's the easy option, centrifugal force keeps the tyre round even without
the air when you are driving fast.
It would have been fun to see them do it on a curved bit.

I did manage to drive a Astra est for 5 miles or so round country roads
and I could not make out what was causing a increase in road noise,the
car handled fine that was my first ever puncture and it continued to run
on the rubber rather than the wheel rim, when it was repaired the
puncture was caused by a horse shoe that went right through the tyre
much to the amusement of the kwikfit fitter

The rear Bridgestone tyre on my Honda (also 45 profile) didn't look
flat but had no pressure at all. The sidewalls on some tyres are so
thick it can be hard to tell.

Yes, I do make frequent visual checks - and occasional checks with a
pressure gauge (plus under-bonnet checks), but - as others have pointed
out - if you pick up a nail and a tyre starts to deflate while on a journey,
weekly checks ain't going to help.

Do you have anything *useful* to contribute?

Renault fit them to several cars, kwikfit sometimes forget and rip the

Unfortunately routine checks don't cover all eventualities.
Does anyone visually check all 4 tyres every time they use their

I can sympathise with the OP as I wrote off a 255x40x17 tyre in a
similar way. At low speeds, on a straight road, it's very
difficult to detect a flat low profile rear tyre.

In my case it was the n/s rear tyre. Fine in the morning. Jumped
in and drove about 300 yds straight up the road on my way home.
Realised something was not quite right, so stopped and found the
flat tyre.
Changed it for the spare, but the damage was done. With the
weight of the car on the fold in the tyre, the carcass had
started to delaminate.

The only consolation, if you can call it that, is that the tyre
would have been scrap anyway, as a the puncture which had caused
it to deflate during the day was an unrepairable one on the
shoulder.

I checked and decided against the option of tyre monitors.
Aftermarket ones rely on wireless dust caps, which are too easily
nicked. I just check the tyres a bit more frequently than I did
before.

You can get sensors integrated into the valve stem that sit inside the
tyre and you can buy sensors that mount around the centre of the rim
with a steel band (bit like a big hose clip) but they cost a bit more.

Remember to tell the tyre fitters that you have the system as the
sensors have a nasty habit of ending up in the bin or smashed.

These look similar to the systems fitted by some car manufacturers;

No connection to the company just the first Google hit that matched what
I was looking for.

Yeah I do. Old military habit. Pressures and tread depth is checked around

It is. Fortunately, this car has the lowest profile tyre I've yet owned,
which is only a 215/55/16, so it still looks like a tyre.

I fitted a set of those valve caps that show a red strip when the pressure
drops. They were just under £10 for the set and work a treat. When I first
got them I kept a check on them with a digital pressure guage - but I'm now
happy that they work accurately and a quick visual check when washing the
car is all that's needed. I've had them on for over a year now and they
haven't been nicked yet.

One day, a mom was cleaning her son's room and in the closet she found a bondage S&M magazine.
This was highly upsetting for her.
She hid the magazine until his father got home and showed it to him.
He looked at it and handed it back to her without a word.
She finally asked him, " Well what should we do about this?"
The dad looked at her and said, "Well I don't think you should spank him."

Every modern car I've driven, bar the Xantia, I find it easy to tell when a
tyre is soft. Up until recently, over the last 15 years or so I've always
had access to, and used company pool cars. They don't get looked after as
they should do and within a couple of miles I can tell whether the tyres are

Don't kid yourself. I keep a close eye on tyre pressures.
Checking at least once a week, and on a run would expect to
detect a loss of as little as 2-3 lbs, simply from how the car
handles. However it can be difficult to detect a flat low profile
tyre at low speeds.

I only drove about 300 yds at a fairly low speed.. A flat
concrete road on the trading estate where I work, which was
enough to start delaminating a 255x40x17 tyre.

Because it was low profile, the rim of the wheel was running on
the fold of the tyre.

With a normal size flat tyre the fold is clear of the rim. The
fold is less severe, and not having the weight of the car on it,
is more likely to survive for a short period without damage.

In days of yore I could always tell by the seat of my pants if a tyre was a
bit flat. But many modern cars are grossly over-tyred, with very wide low
profile tyres which *look* flat when they're not, and don't really *feel*
any different when they are.

At �100 a throw, you don't have to write off too many tyres before a
monitoring system would be cheaper.

Any comments or recommendations?

TIA.

Some of the 'check it' comments might be applicable to the OP (and to
me!) - after all, he says he drove for a while in that state. But such
checking really doesn't address the journey on which the problem starts
to manifest itself.

There are a great many multi-axle and multi-wheel-per-axle vehicles - I
don't have the experience, but I can't believe a low tyre would be that
obvious.

I think that pressure sensors (of whatever sort are implemented) are
potentially a major contribution to road safety. (Hmmm, now where did I
here that before?)

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

As an aside, have you ever told another driver that one of their tyres looks
soft. I have and it is normally met with apathy of abuse. Yesterday I told a
young woman and at least she giggled.

I just cannot image how badly some cars must handle with a soft tyre.

Soft tyres and failed brake lights seem to be ignored by many.

Yes. It is. They do. They are. :-)

Sometimes the difference in shape would be obvious to someone walking
past the vehicle.

Soemwhat frightening when you see them that bad at 90+ on a busy motorway.

My experience too.

I have stopped telling people for fear of their reaction.

Roger Mills coughed up some electrons that declared:

Does anyone out there have any experience of wireless tyre pressure
monitoring devices - the sort which have special valves containing a
sensor, and a central display with LEDs and a bleeper and report status?

The difficulty comes with mounting something with a bit of electronics and a
battery as an aftermarket valve-stalk attachment (eg think of the wheel
balance and the forces on the stalk doing 70 down the M1 with your R14
wheels or whatever). It can be done for large trucks, but everything's a
bit bigger and slower than for a car, so the relative problems are
lessened.

Lots of solutions exist as a manufacturing option where they get to mount
stuff inside the wheel.

My advice is to get the easiest to use tyre gauge, keep it in the glove box
and use it once per week or fortnight when you check your washer water or
whatever.

Halfords are selling a digital one branded Michelin which I've got
(previously having use the old fashioned but ever reliable mechanical
ones). Seems quite good and just a little bit quicker, little bit easier
which is what you want for a boring routine job.

Cheers

Have you tried using eyes? They're wireless and great for detecting low
pressure in tyres, using a system of pattern matching against stored
reference patterns. You have to use them fairly regularly. I use mine
before every drive.

And presumably you also have a system of elaborate mirrors so that you can
watch the tyres while in motion?

As others have testified, if these very low profile tyres lose pressure,
they're knackered in very short order!

S'okay, I was taking the ****. You just set it up so good!

I can't imagine it does the wheels any favours either

I thought some cars use the antilock braking sensors to compare the speed of
each wheel - over a significant distance. If one is revolving at a different
speed consistently then it warns of a puncture

That quite clever. Does it warn of four punctures while you are going
round a roundabout? Or one, when one wheel is spinning in the verge? :-)

MINIs do that, or at least the latest revision.

Dunno. Mine doesn't. Besides which, I don't know whether that would work.
There is a school of thought which says that the distance covered per wheel
rev is determined by the amount of tread laid on the road - rather than 2 x
Pi x standing height. If that is that case, a soft tyre would not rotate at
a higher speed than an inflated one.
