TOWING AND TPMS HIGH PRESSURE ALARM

[bakepl]

Those of us towing heavy with high towball download will generally need 50+ psi in their rear tyres to avoid over heating (outside the EU perhaps). The TPMS will only allow 49psi max cold to be set and in a warm to hot climate it does not take long for the high pressure alarm on the rear axle tyres to be set off, this then seems to intermittently lock out the scrolling functions on the centre screen (just when you need them) . I have raised this with Ineos chat and received the following response: 'Our engineers are aware of this and there is no ETA or date when the software upgrade will be available.' I know Ineos engineers will be busy with their other projects like the EV etc and this request in the scheme of things this could be considered trite..... but could I please ask those forum members who tow to contact their dealer and 'Ineos Chat' about this and ask for a fix - surely this is a minor request and it cannot be that hard to widen the 'not fit for purpose' parameters of the TPMS they have set for the cold tyre pressures. I has at a guess that not many of the 'engineers' who programmed this have ever experienced towing with a heavy load over the rear axle in hot climates. Fingers crossed with a little effort of owners it can be changed in the not too distant future. (otherwise its a fantastic towing vehicle and great replacement for my LC100)

I will add towing to the list of tyre pressure requests listed over here (already has highway, offroad and sand pressures) and here (a Towing sub menu or additions to the existing Temperature menu).

I reminded my dealer of the thread yesterday, they have previously said INEOS staff read it.

Yes they need to dumb it down to work like every other TPMS... guess it's like the 90 litre fuel tank.. fine in the EU but..... otherwise the vehicle is fantastic, don't care about the footwell non issue, steering non issue, nor the fact it's not the worlds best rock climber or whatever, it's just a great all round tough 4x4 and excellent tow vehicle out of the box.

There is a difference between designing an Info console and the real world experience of using it remotely. We need to constructively bridge that gap.

Done! Emailed my local service agent and contacted Ineos through the chat system. I agree with your observations. Not being able to reset or clear the "fault" is a pain in the arse. The on screen pop up that comes up when you try to clear or reset, to check the owner's manual is useless. There is nothing in the manual advising of these limits, or how to clear or reset faults.

Cheers, now I'm South in the cool for a while it's no problem.....guess they only tested the extremes of this feature in ól blighty and not down under in summer.. oh well... guess they'll get to it eventually.

Grenadier TPMS, I wish to remove it entirely!

Either the User Guide is incorrect or there are other ways to adjust the temp tolerance to suit ever changing driving conditions or load, or I am not operating the TPMS correctly.

I am totally onboard with the Grenadier, its design, handling on or off road and all its nuiances (my tenth 4x4 over 40+ years), including the obvious 'Built On Purpose' with compromises. I learnt many years ago adjusting tyre pressures to suit ever changing road conditions, the load and air temperatures are paramount to safety and wear.

We just returned from 4 weeks in Outback Queensland. Left Canberra @ -2c eventually to Longreach after 5 days back country driving @ 32c, all up a 5,000km trip. Perpetually living with tyre warning errors on the dashboard for the ENTIRE trip either Cold/Hot, with or without camper, bitumen or gravel, (100kms/hr on bitumen or 50 kms/hr gravel), naturally adjusting tyre pressures to suit. The Grenadier performed very well on gravel of all types even with substantial corrugations (lower pressures) or sharing the narrow roads with large road trains on and off the bitumen (even half on half off)!

Surely INEOS engineers cant expect drivers to reset TPMS settings many times a day (or waiting for tyres to cool), to eliminate tyre temp warnings? There must be some reality here. I had reset the TPMS many times almost every other morning (as per User Guide). I use the 'Maxtrax Indeflate' (with 2 hoses, just rear or just front), yet the TPMS readings always differ on either side, regardless of sun, air temp or time to reset etc.

Even if this last trip was more of a shakedown for more extensive planned trips later, living with this is just rediculous. I now have 20,000 kms on the clock, they have always been incorrect.

Why isnt there more attention to this or do most just drive around the suburbs?

I think they just need to widen the parameters for pressure and temperature, I like having the TPMS but yes it is a bit too sensitive. You only really need to know when you have a puncture or when temps get high enough to cause tyre damage.

I have just covered around 5,700km to Central Australia and had the same experience. I degree difference will set the between two tyres will set the notification off and you have to keep activating the indictor stalk button to get it to go away (for a short period). Then there is the tyre rotation issue where the car does not recognise the sensors once the tyre rotation has been completed. To make things worse, a 5 tyre rotation will really throw things into a spin! The best that the dealer could manage during my last visit was to get front and rears in reverse order. They tell me they need to reprogram each individual sensor after a tyre rotation.

Yes a real pain, please contact your agent and Ineos. I was advised by Ineos ages ago that their 'engineers' were aware of the issue but wasn't on their 'to do' list basically. Hopefully with enough people bringing the issue up they will address it. Just dumb the system down like every other off the shelf system would be fine enough. Otherwise the vehicle does exactly what Ineos says it does and does it well. Yesterday completed 1200kml straight drive (with rest stops) and the vehicle performed superbly. Very comfortable for the entire journey. For those wondering the steering and left foot rest (RHD) a non issue.

I found the corrugations to be the Achilles heel of the Grenadier but this is probably because my tyre pressure's were still too high.

What tyre pressures did you run on corrugated roads whilst towing?

I have just covered around 5,700km to Central Australia and had the same experience. I degree difference will set the between two tyres will set the notification off and you have to keep activating the indictor stalk button to get it to go away (for a short period). Then there is the tyre rotation issue where the car does not recognise the sensors once the tyre rotation has been completed.

Whatever you do DO NOT rotate the tyres! You're only accelerate the wear even if recommended and described by the manufacturer. This is common knowledge in the motor industry.

Having worked pumping fuel at a garage in my youth (yes VERY old days) for 15 years, got to change and repair many tyres, Particularly road tyres.

To explain.

Run your hands gently on top of the tyre tread forwards the gently backwards. You'll notice at the edge of each groove it is slightly raised (like a saw tooth) more on one and not the other, Mainly due to breaking. Naturally, presuming you have good wheel alignment, balanced wheels including camber etc.

Therefore if you rotate the tyres to different sides, your tyre will turn in the opposite direction, Very soon this wears down that raised edge quickly and starts a new edge on the opposite side of the groove. You only accelorate the wear each time you rotate.

Move the wheel from front to rear and rear to front. The front wheels do alot of brraking and steering and that's not considering off road work.

Hope it helps.
