I've had a set of larger upgraded alloys and tyres fitted to my RRS Supercharged. They were fitted by Land Rover here in Portugal who also calibrated the tyre pressure monitoring system to work with the new wheels, however, after a day of driving the light on the dash stating TPMS Fault showed up.
I took it back and they fitted a new TPMS system but again after a day of driving they light came on. I'm due to take it back to Land Rover again next week.
I've checked the tyre pressures and they seem find. I noticed in the manual it says the TPMS may not work with upgraded alloys.
My questions are has anyone else experienced this and is this a problem that can be overcome.
I'm not sure if Land Rover Portugal have enough experience to fix the problem so maybe with some advise I can point them in the right direction.
Any help would be much appreciated  2008 RRS Supercharged

I believe the TPMS sensors are in the valve caps and do need to be calibrated for a larger rolling radius. It could be that the dealer is not being entirely truthful when they say have recalibrated.... do you have the choice of another dealer?
