TPMS not required?

I recently purchased four new/used TRD offroad wheels and tires for my TRD sport.
The wheels only have std rubber valve stems so i was expecting a dash warning after
install. There is no dash light just just the trucks inability to check tire psi on tire pressure
info page. So without any tpms sensors is there no fault recorded?
Thanks

 

You've not driven it far enough yet. The light will come on.

You have to drive a certain number of miles before it realizes there really is no signal. Its a 'feature' that reduces false positives.

 

I run 2 sets of wheels with my 2017 Tacoma. The TPMS are in the one set but not the other. When I put the winter rims on with out the TPMS the only thing that happens is a light will come on in the dash. I usually will go 15 miles before it even comes on and just ignore it. Last year I retired and took a part time job 4 miles from home. I only saw that light come on 3 or 4 times all winter. I hear guys saying they put a piece of tape over it so it doesnt bother them. I never needed to do that.

 

Ok thanks i've only driven probably 10 miles or so. I ordered 4 tpms sensors for the "new" wheels online and was hoping I could
return them $140. I am curious if I have these installed will the truck not recognize the stock TRD Sport TPMS sensors when I switch
back to my old tire/wheel combination?

 

I believe they've been federally mandated since 2008, so I imagine the warning is coming.

I imagine they'll just need to be reprogrammed and then you'll be good to go again. It may be as simple as a push of a button, but I'm not 100% sure on that.

 

Have you had the truck since new? Some wheels don’t play nice with tpms so some people will drill four extra holes in their spare so that it reads that instead. Just curious.

 

It is a 2019 TRD Sport I bought this summer. It was a Demo vehicle.
DCSB. I bought the TRD Offroad tires/wheels off CL because they were
taken off with less than 100 miles. $600. Same Cost of new tires so rims were essentially
free. My Sport tires only have 2k miles so I have two sets of basically new tires and rims.

 

You should be able to pick up new TPMS sensors for $15-$20 each. Paying $140 for a set is too much. If you have the sensors installed at the time you get the tires mounted there is no extra cost. Most tire stores will charge you $10-$20 each to install them if you're not having new tires mounted.

If you're going to drive the truck on the highway use the sensors. Battery life is typically 7-10 years, but I've seen some last longer. The factory sensors are still working on my 13 year old truck. Spending the equivalent of about 2 tanks of gas every 7-10 years isn't going to break the bank and it is cheap insurance.

 

Most shops will charge a dismount/mount and programming fee to do this. They will likely recommend balancing as well, since the TPMS will be changing the weight dynamic of the wheel. Call around and ask questions. $30/corner, another $120, would not be unheard of.

And if you reinstall your OE wheels/tires for season change, the system will have to be reprogrammed. So $ 2x a year for programming.

 

As I asked yesterday in post 13 of this thread https://www.tacomaworld.com/threads/tpms-bypass.684874/#post-24160294

Where are you finding these prices for quality stuff?

 

So the way the TPMS works is each sensor has a unique ID that it transmits its data attached to. The truck is programmed to look for data from ONLY those 4 unique IDs that it's been told to.

Anytime you switch to a set of wheels with different sensors, you need to program into the truck what sensor IDs that it should be looking for. The dealer or a tire shop will charge to do this each time, if you plan on swapping often for winter tires etc, I recommend looking into a tool that allows you to do the programming yourself.

I have this one:

$219 Autel MaxiTPMS TS501 PRO, 2025 TPMS Programming Tool Same as TS508, Up of TS501 TS408S, Relearn Activate 99% TPMS Sensors, Program Autel MX-Sensor 315/433MHz, TPMS Reset & Diagnostics, Lifetime Update

https://www.amazon.com/dp/B00BHCFNTS/ref=cm_sw_r_cp_apa_i_ywIxFbEV6F33A
Its very easy to use and works on almost all makes and models. There are plenty of other options out there as well.

 

Don't get too comfy the light will come on at some point.

 

Such a pain that these even need TPMS sensors anymore. My golf just uses the ABS sensors to detect a change in rolling resistance and figure out pressure. Set the tires to 30 psi and press a button on the dash to calibrate. Easy peasy.

 

My wife's Honda uses the wheel speed sensors also, makes switching winter / summer tires much easier. For cars that's great.

I'm glad the Tacomas use individual sensors though, makes airing down much easier. The individual sensors let you monitor pressure while sitting still and for each tire. Much better for off road application.

 

The internal TPMS is pretty useless for airing down though I suppose on a pinch you could use it. Firstly it’s not very accurate and secondly It makes large jumps in changes. Most people use the gauge on the deflater.

 

An option that I used was to find a tire dealer that can clone the sensor IDs. My dealer here, Commercial Tire, was able to copy the fours sensor IDs on my first set of wheels to a set of programmable sensors on a second set of wheels. The advantage is that the ECU doesn't see a difference between the two sets. I swap back and forth between my winter tire set and summer tire set with no TPMS warnings. I think they were $50 each with programming.

 

They aren't super accurate but much better than a light not telling you which tire or anything other than low. Had the this come up last weekend with a Lexus GX not having individual tire pressure displayed. On anything going off road the individual reporting is much more useful even if it isn't perfect. These aren't F1 cars so 2 or 3 lbs isn't the end of the world.

 

make a pipe bomb. put behind seat. forget it.

 

Thanks for all the help guys/gals. I'm leaning toward driving without TPMS installed in new tires and wheels.
The warning finally came on today. Save $140 on TPMS, $100 on install and $30 when swapping tires.
Just have to check air pressure once in a while and keep an eye out for a low tire.

 

Are you storing your old tires and rims near where you park every night? The truck might not know the tires/rims are not bolted to the truck.
