You should maintain the same cold tire pressure year round. I run 42psi rear and 38psi front on my Vintage … year round… I just have to check a little more often when it gets colder … You wouldn’t want to under inflated your tires …

The TPMS sensors read tire pressure… It’s the VCM where the values are stored to show the psi levels and trigger a warning if low.

We don’t have access to make changes … I don’t believe the dealer can either … Change like that would probably have to come from Polaris/Indian.

 

To be clear(er), I don't want to set it to a low pressure. When I first get on in the morning the pressures are 35F/38R. But, the light still comes on. On a good warm day, it goes off after driving for a bit. This summer, the light never came on. And, now that the days have been cooler, it seems to never go off.

 

Don’t the wheels have to make numerous rotations in order for the tpms to register?

 

Yes. It takes a few minutes sometimes to register.

 

Air pressure will naturally lower (condense) when cooler or cold ambient air temperaturs are present and can also rise (expand) during warmer or when hot ambient air temperaturs (includes surface contact temperature) are present.

Look at this way, the tire manufacturer's all have to provide PSI settings, provide speed limitations or limits for recommended tire inflation rates for safe useage per each tire design, as everyone knows tires are also made for different reasons/use and of couse for many different types of vehicles, motorcycles, etc.

The TPMS on our motorcycles can only provide the current or actual PSI of each tire in real time. If you know a particular tire requires 42 PSI to operate safely, and as it is designed to be used and should the PSI goes down or up beyond the manufacture's required limts then who's actually liable.... you are. If Indian/Polaris would let any owner manipulate the TPMS notification/warning system on a vehicle or motorcycle built by them and you have a blowout or wreck due to operating the vehicle with over inflation or underinfaltion of what the tire recommended PSI, speed limitation, weight load etc, etc is, then Indian could be liable for your misuse of the TPMS while operating the vehicle with incorrect +/- tire pressure.

IMO: It will never happen, and Indian should never make it available for anyone to manipulate the TPMS on any road/street vehicle.

 

I don't think we have anything to say about the thresholds. I had my tire pressure warning light come on one hour into a ride, like an idiot I forgot I could see both tire pressures on the lcd and I pulled over. Impossible to check manually on The Springfield and when I restarted the bike the warning light was off but it came back on again about two hours later this time I remembered the lcd and toggling through Front:37, Rear:41.


The next week I asked the Indian service manager about it and he said, "Just keep the front at 40", that was the fix.

 

Yeah you need to add air to bring up the cold air pressure. Those are way too low of a pressure. And yes it will go off as the tires heat up. But you don’t base air pressure off a hot tire

and no you can’t adjust the threshold
