New Prius XLE - Wheel Question

Either 42611-47551(Dicastal) or 42611-47671(not Dicastal).

Toyota sources the wheel from two different manufacturers, so there are two different part numbers. I'm sure they're 100% mechanically interchangeable, and probably 100% cosmetically interchangeable as well. But if you want to be completely certain they're cosmetically identical, you'll need to pull off a wheel and check the back for which logo it has. It will either say Dicastel or have a logo that looks something like ( S ), where the S part is shaped like the Sennheiser logo. I tried to find out which brand the logo belonged to, but I hit a brick wall. One source said they come from Thailand, but I couldn't narrow it down beyond that.

 

Yes. One wheel to rule them all, one wheel to bind them.

 

Does anyone happen to know the part number for TPMS?

 

42607-47020 VALVE SUB-ASSY, TIRE PRESSURE MONITOR - $100.02 MSRP

 

If this is for a temp spare, I would just use a regular valve.

 

For a compact spare, absolutely. I don't even know if the sensor fits in a compact spare.

For a full-size spare, it depends. If you're going to be keeping the spare in the car at all times and/or rotating it with the other four tires every 5k miles, it's probably worth installing the TPMS valve and getting some sort of scantool that allows you to register them yourself(so you don't have to pay a dealership to do it for you a couple/few times a year). But if you plan to just leave the spare out of the car most of the time and not rotate it, then it's probably not worth the hassle/money to use a TPMS sensor over a regular valve.

 

When our TPMS fail, I'll probably just go to reg valves. AFAIK that's still legal up here.

 

That's not required - the manual explains how to register them yourself, and switch between 2 sets, via the multi-information display.

 

Nice. I had heard that, but hadn't checked the manual yet to be sure. Way nicer(and cheaper) than the old days. I like that there's the option for two sets of tires, but I wish there was an option to include a spare tire. You can still use a fifth wheel/tire in a rotation, but it looks like each rotation will involve more programming steps.

 

Apparently the catch is you need to make sure you've got new-enough sensors (post-2018?). So make sure no dodgy dealer tries to give you an old part.

Although maybe that's not really an issue, due to non-removable batteries? Old ones should be well past their best-before date...

 

@KMO how did you managed for the winter tyres 19". Now in EU prices went bananas.
And i do not know if the various ADAS or sensors get confused passing to a 17" set..

I got the 17" optional 5-point dark metal rims from the EU accessory/option brochures, fitted with 215/55R17 Nokian Hakkapeliitta 10s.

Rims shown here:

Wasn't particularly keen on that wheel style, but I think they look better in the flesh. And I guess it's nice to change style occasionally. I'll certainly know which season it is.

That came to just under €2200, I think, including TPMS and installation.

Although Toyota Finland are now including winter wheels+tyres free on Priuses along with various other models: https://www.toyota.fi/tarjoukset-kampanjat/toyota-talvirengaskampanja

Site doesn't say what exactly they're specifying beyond "winter tyres with alloy rims €0", but I imagine it's the same as what I got, possibly with friction rather than studded. (They say "worth €2372", and my bill indicated a couple of hundred euro discount. My first estimate for 19" was over €3000).

Overall wheel circumference isn't changed significantly by the 17"/19" change, so shouldn't be any sensor issues.

I had been expecting to need a "change inspection" for the rim size change, but that was waived - I think Toyota Finland did their type approval paperwork.
