TPS ?

[ymfb]

As I’m going to ride 1500 odd miles this week I decided to prepare and physically check the pressures, which were 1.6 and 2.0 bar, I pumped them up to 2.5 and 2.9, there has been no low pressure warning, which I recall the trigger point being > 0.1 bar below the recommended but cannot find it in the riders manual.

I have until this today relied on the accuracy of the tyre pressure sensors and they have previously been accurate. Clearly I should not have been so complacent

So from now on it’s back to manual checking.

I assume the likely problem the tyre fitters did something incorrectly and they are buggered?

NEVER rely on TPMS, imho. It is far from infallible. I was out last week ahen the warning light came up indicating a low rear. Stopped and checked it and it was at correct pressure. Switched ignition off, and on again and fault cleared. My brother today had a puncture on his Lexus...tyre was at 10psi when I checked it...his TPMS system didn't register a problem.

Mine only activated at 0.7bar

How long had your bike not been ridden, and TPS only works when bike is moving, is my thinking, and I think post 3 sounds about correct.

Rode it to Swindon and back yesterday, roughly 2 hours, 60 miles. It’s ridden most days, but not everyday.

Wow so how did the tyres get so low.........1.6 and 2.0 bar, did you not feel the difference when front was at 1.6 it must have surely felt weird..........

Why not ride with the tyre pressure readout showing constantly rather than rely on low pressure alarms?
I usually ride with my speed in the upper window & tyre pressures in the lower.
Or if you’ve got a Nav 5 or 6 that can also display your tyre pressures.
I find it very Re assuring to know what they are in real time, especially when riding with a known puncture!

This - I want the earliest possible notice that the pressures are dropping.

Or apparently this works also with the phone, some on here have it already I believe.

I prefer to have the fuel range and temperature showing, but since Monday I have been scrolling round and checking the tyre pressures fairly regularly. As I’m an age where nearly all the bikes I have owned did not include TPS it probably stared off that I didn’t trust them, slowly followed by a gradual conversion to relying on them. That’s changed and now back to distrust.

I will bring it up at the 30,000 mile service, unless of course it gets traded in before

Can the TPMS be set to give readouts in PSI rather than bar?

And, as the OP mentioned tyre fitters, it got me wondering about the spoked wheels on the new 1250 GSA – is it OK for any reputable tyre fitter to be let loose on the gold spoked wheels with TPMS or is it better (safer) to get the Motorrad dealer to change tyres (given it probably costs double the price)?

I think the warning light only comes on when a sudden loss of pressure occurs so wouldn’t come on if it is say just a very slow leak from a valve

If the this is a TFT bike, the RDC limits may be set by the rider, as well as the ability to deactivate the entire warning.
On a 'Clocks' bike, I have not been able to find the exact warning threshold, but for the bikes in my ownership, the warnings have typically come up when the corrected pressure have dropped by 20-30%.
