New Rav Tpms

Recommended Posts

When I bought the new RAV I did not know that it had the simple (non USA version) TPMS fitted. I listed the Pitlane II wheels as options and kept the silver alloys for my winter rubber. After reading a couple of the posts below I've decided to just order the valves for my winter wheels as when I'm away my wife can forget about checking tyre pressures and it's not the first time I've had to pump them up for her on my return.

So, firstly I've ordered the new tyres, Goodyear Ultragrip 8 Performance 235-55/18 H 104 XL @ £170 per corner delivered to door. My local Mr. T is charging £292 for the TPMS and £40 to fit the tyres. £1012 all in.

Keeping the car for five years works out at £202.40 per year which I think is reasonable for peace of mind and safety. The winter wheels/tyre/TPMS combo will only require to be 'read' by the ECU once which takes 2 mins and no charge. The ECU will remember both set ups and auto change when swopping wheels.

I've just been admiring the photos of your Rav in the photos section David, it's very nice. I'm in the process of doing the same thing for winter motoring only I'm using the Pitlane anthracite wheels through the winter, I thought they're less likely to show the 'muck'. I've opted for Continental winter contacts at very similar money to your Goodyears.

This is really good news ... :D

I'm assuming this is what your local dealer has told you? Do you believe them? :)

I posed a similar question with my local Toyota dealer last week and am still awaiting a response!

Yes, this is what the service manager told me. Do I believe them? I'll reserve an answer to that until I can test out his claim. When I get the winters on I'll swop over a summer and see. If there is a problem I'll hold them to their original advise and expect free setup at each bi-yearly change.

Hi Chaps.....'Smee here.....thicko....

What two "set ups" has the ECU to remember.....? Are there different pressures for winter tyres?

No, not quite ... the ECU knows the identity of the TPMS valve in each wheel so it knows which pressure to monitor. The two set-ups are the four summer wheels and the four winter wheels.

The piece of useful additional information that GreyRacer has brought to the debate here is the assertion that the ECU is capable of knowing about two sets of wheels (their TPMS valves to be precise) and that it has the presence of mind to automatically switch between the two. I'll believe it when I see it - but I desperately want it to be true! :)

I've established the same facts, fingers crossed !

It'll have to remember two sets of sensor valves Kev - keep up :rolleyes:

That's if the ECU has the capability to store eight sensor codes................

Edit: see posts above :thumbsup:

Right, Philip.......capiche.......but good luck.......when I wanted a fifth sensor logged on to my SR180 ECU, I was assured it would only store the original 4 fitted ones. Pants......it took the fifth no bother, but I wait with interest can it store 8 different "IP" type addresses....?
