My Enkei Evo5 rims just arrived and I was told by a friend with a TC that I have to get the valve stems swapped from the stock hubbies to my new rims.

That would entail me having to take off all four tires from the stock rims, removing the valve stems, putting them all back on, taking all the tires off my new rims, replace the new valve stems with the stock valve stems, put all the tires back on and then high speed balance my new rims . . . again (they came from the store balanced already).

I think that is the biggest load of crap Ive seen in a while. As you can tell Im pretty ripped about this. I just wanted to take my stocks off, and put my new Enkei's on, but noooooo. Scion makes things complicated.

Is this true!?

 

you can roll w/o the tps right?

 

You'll be fine without the TPMS Valve Stems. I think most people with aftermarket wheels didn't bother with swapping them over. You'll get the light on the dash because the sensors aren't there, but other than that it's not like your car won't work.

 

I can't stand stuff that has been done half ___ though. I guess no one has swapped rims yet to know.

 

Have you looked through the wheel/tire forum? A ton of people have aftermarket wheels. There are also several threads about TPMS and issues related to swapping them, not having them, etc. Did you not know you had them before you put tires on your new wheels?

 

I bought my rims and tires from wheelsnext and they actually mount and balance the tires for you then ship them to you.

So no, it didn't cross my mind that I needed to swap them. I am thinking about just going to my dealership and getting a new set of them for my new rims. We will see.

Oh and I do believe I am in the forum that relates to my car in the category or Wheel & Tire.

But thanks for letting me know. I will check there.

 

Yeah you're in the right forum. I only ask if you looked through it because you said "I guess no one swapped rims yet to know".

It will probably be cheaper just to swap them from your stock wheels to your new ones. With new ones you have the cost for parts, then they have to program the new ones into your computer so the TPMS will recognize them (or so I've read) which they'll probably charge you extra labor for. That would of course leave your stock wheels without, but I don't know if the computer would recognize more than 4 TPMS sensors anyways.

But before you go through the trouble of either swapping or buying new, make sure the TPMS sensors will mount on your new wheels. I've read some wheel designs don't have enough room on the rim/barrel for the sensor to mount. Tirerack will probably know, they sell Enkei's.

There is also talk of rigging a PVC tube, sealing it with a valve stem on one end. Then you put the four sensors in the tube, close it, and fill it to like 30psi. Then keep the tube in the car and it will read fine no matter what wheels you run. Not sure if anyone here on SL has done it yet though.

I read that the government is requiring all manufactures to start making TPMS standard on cars. So in a year or so just about every car will have them.

 

I had no idea that the gov't was making manu's do that now.

Thanks for the info. Putting them in a PVC tube requires almost as much work as it does to put them in the new rims. I will see how much this place that I know of will charge me before I make anymore decisions.

Thanks again for your quick response.

Hindsight is 20/20 WheelsNext.com sucks with a BBB rating of C+. Their communication is terrible!!! I have a BBB claim against them right now.

I bought my wheels & tires from WheelsNEXT.com back in December!! I made sure my setup came WITH TPMS sensors installed. I paid a lot of $$ and can't use them because, the ID codes for the TPMS sensors were never provided. It looks like my only choice is to have the wheels broken down also but just to get the ID codes.

I want them to pay for the cost!

 

I had a great experience with them. I canceled my order 3 times in one day and they told me that Enkei was out of my rim style so it would be 10 days to get them in and 1 day to ship them to my house. They got it to my house in 9 days. I was excited.

That sucks that its not working for you, but your right, they should pay for the installing of the TPMS.

 

The TPMS "serials" have to be programmed to your xB, so you're better off having the stocks ones reused. That way, you save a trip to the dealership. To my knowledge, the only way to add the serials are through the Toyota scan tool.

TPMS run ~$100 each... so yea, that's definitely another hurdle to jump if you do decide to get a new set.

Do you know how to GET the ID Numbers off Sensors already installed. I have 2 sets Stock Steels that came with my xB & another Toyota/Scion set that came with my after market wheels. Right now I have been told the wheels have to be broken down each time so the correct ID can be programmed into the TPMS computer. This will cost a lot of $$$ & just does not make sense!

Obviously, I don't have the codes for any of the wheels & if I do have ALL 8 broken down, then how do I keep track of which numbers are for which wheels? I understand that after each tire rotation the TPMS must be updated as to which tire is on the vehicle?

There are a lot of posts on TPMS but this area of information is not clear yet. I have spoken to a couple of dealerships. One says the wheels have to be broken down each time the other says the ID numbers can be scanned & read without breaking down the wheels!

I know LongoToyota is the highest volume dealership Toyota has so, your dealership must deal with this issue daily!!

 

I dont think it matters WHERE your tire is as long as the TPMS is still near the car. Who knows, that does bring up a good question. How does the TPMS tell you (through the dash) which tire needs to be inflated?

I might just have my new rims installed and just live with the CEL.

 

Pulling out your gauge cluster and just putting a piece of electrical tape over the LED seems a lot cheaper to me...

Roll of electrical tape is a lot cheaper than getting tires dismounted and remounted. Twice. Lol!

 

Yeh, but the wife just today noticed the light & asked what it was for and I had to explain that I paid for the extra sensors but now they don't work. It's one thing if they were $25 each but at $87 each, now it's a problem.

I will hear about the light EVERY TIME she gets in the car! I will think about the $$$ for sensors that are in the wheels but not getting read.

 

it's not really that expensive to have a tire shop de-rubber a rim, granted you need 8 done... still not that bad overall for some peice of mind... tax time is coming up soon, so maybe a little extra $ is coming your way?
or, if you have a trade or adult school nearby, they will probobly do it for free for you for experience..
i know my old auto shop teacher would let anyone and everyone bring their cars in to run on the dyno we had, and we were tested on hooking everything up rght,, strapping down the cars, etc......

 

The IDs are actually stickers on the sensor itself. To my knowledge, they haven't added the technology where the scantool can pick up the signal (they are obviously wireless connected to the monitoring system) and return the codes.

The programming involves using the Toyota Scantool (you may hear being called "The Toyota Brick") and can't be done with out (at the last time I checked).

I'll double check the repair manual pages specific to the xB to see if any of the features I'm hoping for (wireless serial# read, external serial program method) have been implemented... but sometimes (ok, always), we think faster than we're given the tech =P

And the position of the monitor does not matter. Toyota's system detects pressure differences and reports variances to trigger the light. It does not tell you the specific tire it's from. The official reason is "We want to ensure consumers are regularly checking their tire pressure and do not solely rely on this system for it."

And for anyone reading this for fun and have checked all their tires when the light was triggered... make sure you check the spare's pressure. That has been the culprit in most cases (I think the xB2 has a spare sensor... I'll check @ work later today to confirm)

Alternatively... it's not really recommended... but you open up the cluster and remove the tpms warning light bulb... lol. No bulb, no illumination! Luckily there isn't an audible tone

You might want to take ih8onyu's advice. Look for a local adult school (or tech training school, or even a community college) that offers an automotive program. They usually take victi... volunteers' vehicles for minor services. They will have a schedule based on their agenda, so you get an idea when they will do it for you.

If your local place has you sign a waiver for the work that they are 'no responsible for any damages' etc etc... then you may want to run away Just make sure you tell them there is a direct-type tire pressure sensor mounted on the stem. Hopefully the instructor has seen a few newer vehicles come through...

After that, I'd just have an actual tire shop touch your new wheels.

Thanks for the response. It's the different perspectives that make Scionlife great.

Getting the numbers off the Stock units first makes sense and my local dealership will likely help me. I think I will suggest they offer providing the ID numbers as a FREE Service they can offer via coupon at an upcoming Scion meet at the dealership. (Bring in your Scion for Oil change & Tire Rotation & Dealership will provide the ID Codes written into the Scheduled Maintenance book)

For the AfterMarket Wheels, I will consider the tech school angle also. Free is good but damaging an $87 sensor Per Wheel & possible scratched rims from NOOB techs do concern me.

I have considered the Harbor Freight $39.99 Manual Changer just to break the bead & read the numbers but I am afraid of the cost of the damages if I do it myself!

 

My mistake on the spare. No spare sensor is present.

Also my mistake on reading the values off the sensors. It seems they did add the auto-detection in the current line of sensors, so they are registered when using the techstream tool

 

WOW, Great, about the auto detect issue!!!

Is there any way to quote & post the information on here? It would be a GREAT STICKY for the whole site and SAVE A HUGE amount of cash duckies as it were!!!

Thanks for checking into this!! Everyone's response had been to just tape over the light but a little diligence paid off. Great work!!
