Aftermarket TPMS?

[The Other PaulG]

Reading a Chris Scott tyre article, I see that there is a wide range of aftermarket TPMS systems available.

Has anyone tried them? Any thoughts? Given the identical list of functions for all of them, it makes me think they might all be very similar internally. My only concern perhaps is that they seem too cheap! But if they work, £30 to know your TPs are ok as you rip through Germany at three figure speeds on hot roads would be very reassuring.

I had the Garmin ones in the past on bikes without built in. They link to Garmin devices. They basically fit into the tyre valve and have a small battery. Is that what you are looking for?

You discover very quickly if you lose pressure in those cases

What bike are you on?
Have you considered or looked into the possibility of "activating" its own TPMS? It can be retrofitted in some cases.
Saves you having to always use a GPS (Garmin solution) or add other crap to the bars.

Yes, I too hate clutter on the handlebars. To that end, I don't use a satnav, Garmin or other. My bike is a 17 year old Guzzi so I doubt it has its own TPMS functions.

I may not permanently mount the display for the TPMS, just handy to be able to do so for long fast rides (where the mind has time to drift and ponder issues such as rapid deflation..)!

If the aftermarket systems work, I'll give one a go.

FOBO is a good system, it connects to your phone for pressure reading and temperature.

I used it on my V7 and it just told me over my comms if pressure was low as it would squeak a warning over Bluetooth

No need to worry about three figure speeds then Paul

I fitted the Chigee G3 version to my 1250RS. When cleaning my bike a couple of weeks later I found that the front tyre pressure monitor was rubbing against the RH disc calliper due to the clearances between the calliper and the side entry tyre valve so I took the whole lot off! TBF to Chigee they gave me a full refund and didn't want it back so their customer care was excellent. It would be worth checking if this type of TPMS is suitable to use with the standard non BMW type tyre valves with the rubber bases if you have that type of valve.

Ah no, most probably not.
Will probably also not work in the wet.

I just mentioned as I added TPMS function to my hexhead last week (17 years old too) and works more than ok.

Harsh!

It doesn’t even comfortably get into 6th until 80 plus, I’ll have you know!

Brut33's tubeless thread reminded me that I never concluded this one.

I bought a TPMS system from ebay. Because it's a safety item I bought the most expensive one (although they all looked very similar, quite possibly the same item). It was £18 delivered... https://www.ebay.co.uk/itm/356731126573

the bad -

• it's not pretty
• it also provides tyre temperature info, but given where the sensors sit (they replace the dust caps) I doubt they can measure the carcass temperature at all accurately
• the mount is a bit basic and ugly - I'll be making something a bit more elegant to mount this and the Beeline.

the good -

• very simple to install
• they don't leak (I was concerned they themselves may allow slow deflation)
• they also present the time, and you can set alarms for pressure / temperature
• they are accurate, without being well calibrated

So... the read-out they provide is about 5psi higher than testing with 2 separate pencil gauges. However... you quickly calibrate your brain to accommodate that. What they do seem to do well, is show you changes in pressure. For example, during a ride the read-outs for both tyres will increase by about 3psi... which suggests to me that they're reading accurately.

Therefore, I am very happy with them -I glance at the gauge periodically and as long as I am not seeing any decrease in pressure, it gives me confidence that all's well. On long motorway slogs, I find that a comfort. On that basis, very good value for money for under £20!

Looks like you can’t go wrong for £18 Paul.

Good to know, thanks

I nearly didn't buy it because I couldn't believe it would actually work for such a crazy low price.

 

[DJ123]

i saw a few of these on Amazon and did wonder if they would actually work!

I'm assuming the batteries in the display and sensors are replaceable, rather than chargeable?

 

[GSian]

To be honest they look ok, It's not that important of how accurate they are, just that they'll warn of rapid air loss if you get a puncture.

went riding 2 weeks ago with a new bunch of speedsters. 1 guy had a £29 screw on set, with a handlebar mount that showed current temp, air temp and changed as we rode showing pressure of tyre as it heated up. Small, unobtrusive to clip on a handlebar. Quick release and all the size of a box of Lion matches. He was happy with it. Replaceable batteries on handlebar reader and I think on the screw on pressure sensors. Auto on off as well. If I didn't have a BMW with this function already, I'd be happy to buy them. PS, just seen your bolt on's..his was much neater...

I’ve fitted the chigee Q3 on my 1150GSA
Very happy with it so far
