My wheels are mid way through refurb process and the tyre fitters say they probably can't put my TPMS valves on because Cup2s don't have enough space around the valve.
Anyone fitted them to Cup2s?
Anyone fitted them to Cup2s?
Anyone fitted Tyresure (TPMS) valves on Cup2 wheels?

Sound a bit vague from the tyre fitter, lots of cars have these nowadays, so you think they would have fitted them before, should not be hard for a competent tyre fitter to measure your tpms valve and where it needs to fit and give you a definitive answer either way.if it was me, I would not be filed with confidence after that about them even fitting the tyres to a expensive car that can do 170+ mph.would probably just take the whole lot to a proper tyre place when wheels are done and get their advice and them to fit it all.the place refurbishing you wheels is probably great at that, but does not mean they are experts at tyre fitting, after all anyone can buy a tyre fitting machine, its not hard to fit a tyre, but takes skill and experience to do it properly.but just my two pence worth, cheers
Yes, they had fitted them often before, just not to Cup2 wheels, they were just giving me a heads-up that it was going to be tight because of how cup2s indent the valve into the rim.
Anyway the followup to this is that they do fit and they look good and work well.[

So, 2 and a bit years on, and there's a follow up cautionary tale.
The batteries in the wheels should last 6-7 years but as has been told in the 997 forum with Porsche TPMS the batteries will last a lot less time if you let a tyre go soft.
Over winter my car goes for weeks without going out, so without me noticing that the TMPS is screaming "TYRE SOFT" every 3 seconds for the rear left tyre. It seems the sensors in the wheels go into sleep mode when the wheels are not moving and pressure is correct. But if the tyre goes soft the sensor wakes up to tell you even when the ignition is off. A bit of a silly design really.
So for weeks my rear left sensor was using battery at normal driving rate. It did last long enough for me to see the low pressure when I next switched on, but it's now dead.
Fair enough, but can I find a replacement anyway in UK? - No. But as I have these on two cars and as I can easily see this happening again and as the sensor cost 1/4 the price of a complete kit I decide to buy a complete kit and have a stock of 3 spare sensors. I buy exact same make and model. Mine is a P409. Tyresure have a newer model called P421 so I avoid that.
My tyre man fits it for a tenner and off I go to reprogram the sensor to the central console. But I can't make it work? It does not help that the instructions are in Chinese translated to english using something like google! A few phone calls and the sensor seller can't make it work either. I email the manufacturer in Taiwan not expecting any response - but they are amazingly helpful with clear instructions and then diagnosis because they can't make it work either. Then they realize I've bought a "new P409" and not an "old P409". The sensors changed with changing the model number.[][] The currently sold P409 uses P421 sensors. Indeed a quick swap showed I could either see 1 rear left sensor or the 3 other sensor depending on which console I switched on[].
So they point me to a Taiwanese ebay seller who stocks the old P409 and I buy one from him which today arrived (by very slow boat), hey presto I have 4 working sensors after another tenner to the tyre man.
These TPMS systems are a nightmare to maintain - don't let your tyres go soft when not using the car and if you have a car new enough for an official Porsche TPMS thank your OPC gratefully and pay up the glossy price because they are working hard to look after you[8|]

Yep. Got my kit from D911. Good piece of gear. Nice to know for certain correct psi's in your boots especially when driving with "spirit"! Gives an audible warning when pressure and temps drop below parameters you can customize.
