Fix for air pressure sensors??????

[fdlock890]

Hello all.

I have replaced my stock rims and tires with 20" and toyo 33-12.5 20's. The problem is that the tirese need to inflated to 65-80 lbs, so my tire problem light comes on, and my tire pressure readings are just x's. Is their a fix for this problem? The dealer says the computer can not be recalibrated to the increased air pressure, and that the computer can only read up to 55 lbs. Does anyone know of a fix for this? Thanks Lock

Sorry,I've never heard that before.My TPMS read over 55PSI.
I've never really pumped them up really high,but I know I've seen 58PSI before.I run them at 54 cold.
Have you had someone attempt to recalibrate these or is someone just talking BS without knowing squat?

They will read "X" untill you drive it a ways. I'm pretty sure that they will read at any psi.

[fdlock890]

My sensors will start out with x's, and then they will read 63 lbs for about 10-15 minutes, then the light comes on and the readings go to x's. I am not sure who I could go see that may be able to recalibrate the computer for me. The dealer said it was not possible, but we know how that goes....

Don't run them that high! It says that on the tire as max but you should run them from 30-35psi. Call around to a few shops that sell the toyo's and ask what they suggest running them at. I did that on my toyo mt's and they said 30-35. If you run them that high you will wear the inner part of your tire down too fast. I run mine at 35

I called toyo when I installed my m/t's they calculated original to new and came out with around 60 psi.

Don't air them up that high. 32-35 PSI is plenty enough air pressure for these, it's frustrating to me when tire shops try to use the Max Pressure as if it's a Recommended Pressure. The Recommended Pressure is based on your vehicle and use, NOT the tires themselves. 60 PSI was causing problems for mine too, 35-psi is about perfect.

The purpose of this bulletin is to disseminate Toyo's recommendation and policy regarding inflation and tire maintenance of original equipment tires and direct replacement tires (same size and load range) on multipurpose passenger vehicles.

For the purpose of this bulletin, multipurpose passenger vehicles include all vehicles equipped with LT designated tires or medium duty truck tires. Multipurpose passenger vehicles include recreational vehicles (including class A, C, and B RVs), busses, and EMS (emergency medical service) vehicles.
Inflation of Original Equipment Tires on Multipurpose Passenger Vehicles:


Toyo's policy is to maintain the pressure specified on the vehicle's tire information placard (certification label) as established by the vehicle manufacturer or final stage manufacturer.

Replacement tires must also be capable of supporting no less than the vehicle's GAWR (per axle). Tire Inflation and GAWR Information:
The vehicle's tire information placard (certification label) includes information regarding the tire size, inflation, GAWR and other information. The tire information placard is usually located on the driver's door hinge pillar,door latch post, or the door edge. In RVs the tire information placard is placed on the bulkhead at the left of the driver's seating position.

Thanks for all of the advice. I called TOYO, and they told me these tires should not even be on my truck. I told them they are E rated, and the guy calculated the tires, and the GVW of my titan, and he said I was sold the wrong tires, and to get them off NOW. I know plenty of guys running these tires, so I think HE was FOS. I will drop the pressure, and thanks for all of the help. Lock

You know,if a tire manufacturer told me that,I would seriously consider taking their advice.They are in the business of selling tires,why would he tell you not to use these? Did you ask him the reason why and maybe ask for another recommendation?
Something tells me this guy was NOT FOS !

I have 35 toyo M/T's and from going back and fourth from the dealer to the tire shop making sure all sensors were working and having the system reset. The end result that the shop and the dealer came up with was that my tires were to thick for the computer to get the signal from the sensors.

Too thick for the sensors to read???
I'm sure there are a few members running 35" Toyo's without any problems.
Alot of tire shops are breaking the sensors dismounting the tires.Nissan came out with a TSB instructing that once the outer bead of the tire is broken loose,to unscrew the sensor and let it fall in the tire before removing the tire from the rim.Alternately when reinstalling a tire,once the tire is on the rim,screw the TPMS back on before sealing the bead.Maybe your sensors got broken on removal/install?

No, not necessarily. Too many people who don't know what they're talking about act like they know everything these days and they act like an authority just because they're an employee but they never took the time to learn their products.

Sorry, but unless he can provide a good reason like maybe he didn't listen and is assuming that you're running on stock rims, that guy is a total idiot. Who ever heard of yanking tires off a 1/2 ton because they're E-Rated, that's the stupidest thing I've ever heard in my life!!!! E-Rated is great, our trucks are designed to run on D & E rated tires.

Too many people are running 33x12.5-18 Toyo M/T's (also E-Rated) on their Titans and love them to buy into that BS. The 'E' rating stands for the sidewall strength, size, and angle that provides a weight capacity that's classified in the 'E' range which I think is a great range for us to be in. I'd say to inform that moron's supervisor that he's providing false information that is hurting their customer relations and potential sales.

Here's a link to an 'E' rated set that's been running on an Armada for 2-years now and I dare someone to tell him that they're wrong.

#2 to this..... That sounds EXACTLY right and quite possibly is the OP's problem too!!!!

I'm not saying the Toyo rep's word is gospel either,but I would ask for some clarification other than these are wrong. I also would not totally rely on possibly an 18 year old pimple faced kid behind the counter that put these on his friends truck because they "look sick" either.
But if I was concerned enough to contact the manufacturer because the tire dealer couldn't help me,I would at least listen to their advice,maybe ask for someone else to clarify this before I ruled the guy out for being "FOS"

I have two sets of 35 toyo mt's and they work great..both sets with sensors

[fdlock890]

I called TOYO because I received conflicting information. Discount tire told me these were fine to run, and the are E rated. I wanted to run the air pressure lower than what they had set it at, so I called TOYO to get a straight answer on what pressure I should or could run. The guy at TOYO asked a bunch of questions, and told me that my truck was too heavy for these tires. I scratched my head and reconformed with him all of the information we discussed. So I called Discount back, and they told me that these were E rated and that all of their information says they are fine to run. So then I did some digging, and yes they are E rated, and they are OK to run on the Titan. WOW, what a headache for some darn air pressure info........
