I have the Trialmaster with steel wheels and E rated KO tires which can go up to 80psi, everything from the factory. I set the cold pressure to the 43F/49R and have constant issues with the high pressure warning. Carry 5 people often, however our temps vary 30+ degrees most days, which the vehicles TPMS monitor doesn't seem to like. Ineos really needs to increase the max tire pressure warning PSI or an aftermarket programmer needs to make a way for owners to change it on their own. There should also be a way to acknowledge the warning so that it doesn't keep taking over the screen.
