I had ordered OEM Jag rims and snows mounted with sensors for my 2010 SC from a reputable re conditioner. For two winters I suffered with the TPMS not being picked up. Had main TPMS error for the entire winter. I got the supplier to send another complete set of sensors and had them swapped this week. I mounted the tires today and have driven quite a bit and not one error....which is what the swap procedure should have been like as stated in the manual.

Pleased to say the least despite the $100 it cost to break down the tires and re-balance.

So contrary to what many have said, you do not need the dealer to enter the sensor codes into the ECU when you switch.

 

This accords with my experience. I have now fitted the old wheels and snow tires to a new Jaguar with no TPMS issues. Done correctly the TPMS self learns the second set of TPMS.

I now think the waiting period is only necessary if a new TPMS is fitted. This is because the TPMS stems are shipped in sleep mode to save the battery. It takes the TPMS on the car some time to ping the sleeping stem into action. If the valve stem has already been wakened up the TPMS can find it quickly. I think the TPMS pings the valve stems every 30 minutes or so whether the ignition is off or on.

 

The only variance this time around was 2 things. 1, the sensors, 2 when I picked up the tires remounted with the sensors I asked the tire guy if he could use his basic scan tool to see if they were communicating. The device he had would just hand shake with them and report the frequency once awake. It took about 10 seconds for each to respond and confirm 315.

The tires sat for another week in my garage then I did the swap as I have every other time. Put the car in the middle bay, jack remove, place snow on, repeat 4 times. Then torque to final spec with torque wrench. Left the car (not on purpose) for a couple hours before I took it out to drop my son off at work. Not a single error or even hint that I had changed them. (other than my Blizzaks are quieter now than my 2 summer Pilot SS's which are quite scalloped in front)

I am convinced that the sensors were bad.

 

Cwood, what did the sensors cost you. Were the first or second set oem or other brands? Thanks.

 

both sets of sensors looked identical and were ford branded. The second set were previously enjoyed even as the provider of the original mounted set begrudgingly sent them out to me so I would stop bugging him about the fact that the sensors were not working.

So, no idea what the cost is. I think they were Siemens manufactured but will have to look at them when I get home. I posted a picture of them in a past thread here.

 

JaguNy,

I have been trying to put together a low cost used/reconditioned set of wheels and winter tires with sensors. I have seen many vendors selling aftermarket 315mhz sensors that are compatible with our cars for around $50 bucks each. Do a Google search and you will see a wide selection.

If anyone knows of a decent set of winter wheels/tires I would be interested. I can be e mailed at eo145@aol.com..

I am kind of on the fence with this since I recently retired and stay home most of the time. I do little driving and the winters in New Jersey/NY have not been too bad. I also have an all wheel drive vehicle to use if really necessary.

I may just get rid of my OEM Conti Pro Contact and go to an all season tire like Conti Extreme Contact DWS which is supposed to do somewhat better in snow.

Try Detroit wheel and tire for reconditioned oems and snows mounted with TPMS.

 

Thanks CWood. I will certainly check them out.

I originally wanted a winter tire/wheel 19 setup but struck out, so I bought 20 inch winters. I am charged $160 each time to put the rubber on an off. Adds up to $320/year. I am considering buying a new summer wheel set to avoid this process. I think I could get 50 percent back on the set if I sell th car in 3 years.
