TPMS-tire pressure monitors question.

[Standup]

We have a 2014 Sunseeker built on a Ford E450.
Can I assume that all 6 tires have a tire pressure monitor?
How about the spare underneath?
Anyone? Thanks!

[TURBS]

I don't think it has any.

[Standup]

There is a tire pressure warning light on the front panel.
I should have asked if there were individual tire "sensors".

[dndnva]

We have a set of 6 TST 507 Flow-Through sensors and wouldn't do without them. They work great, wireless monitor is perfect, and their customer service is outstanding. I had an issue with one sensor last year and they talked me through the fix on the first call. I feel such a sense of comfort knowing the status of each tire as we travel. As soon as my new Legacy comes in I will install them before leaving the dealership!

[Campin Cajun]

If your RV is equipped with that system then yes, each tire will have it's own sensor. With only having a light on the front panel you will not be able to tell which tire is low when the light comes on. It would also be good to know what the factory settings are.

[Standup]

thanks, Campin. The standard line is the light comes on "25% below the door post value". So I've been told. Ford E450 manual is typically vague. I can deal with knowing if 1-of-6 is low. Can't see the cost and complexity of a full-on monitoring system. Maybe I haven't heard enough horror stories.

[Campin Cajun]

No problem Standup, you can maybe look into some type of programmer that would allow you to set the low and high PSI to a certain pressure. That way you would know that if the light came on its time to stop and check pressure before the tire blows out.

Full monitoring system only cost me $300 installed for my dully. Check Americas Tires.

[Joseph Carozzoni]

We have a 2014 Sunseeker on the E450 and there are no sensors. We went with TST and the version with the user replaceable batteries.

lower the pressure on one tire in the back and you will know if system works or not.

[TURBS]

I'm pretty sure they stopped at F350 srw. No duallys.
I've been wrong once before.

Can't remember anytime you were right other than tricking Ms. Amy into marrying you.

[TURBS]

Now that I think about it, just because you can see the tpms icon on the dash doesn't mean that it's equipped.
They probably use the same dash insert for many applications.
My truck has the active skid control icon on the dash but my truck doesn't have asc.

Or put proper pressure in your tires on a warm Colorado day, especially at altitude. The next day when it drops to zero and you go down the mountain, you will likely know whether or not the TPMS is working. This is a common Colorado issue. Some tire shops reset the TPMS to lower pressures when installing snow tires - I'd rather see the light and realize I need more air in the very cold temps.

I have never seen a spare equipped with TPMS in passenger cars and SUVs - but I've never had a motorhome either.

As it turns out, there is no TPMS on this rig. There is no warning light after all on the dash. I just saw the one in the Ford E450 manual, and made an assumption. Went to Les Schwab, they could sense no signal. Big trip next week. I'll be checking pressures daily. What an industry.

[Standup]

Actually, I notice that there is no TPMS warning light on the front panel. I saw it in the Ford E450 manual for the van, and made an incorrect assumption. Went to Les Schwab where they could sense no signal from transmitters. Guess I'll be checking pressures constantly for now. Big trip next week. What an industry. Does the gross weight of this C put it over the Fed's requirement for a TPMS? Is that it? Will check out the aftermarkets when I have time.

[f5moab]

I wouldn't worry about it if it is a new vehicle with new truck tires. I don't mean not to check them occasionally, but chances are they will be ok. I can still remember the days when TPMS was a dream of some congressman.

I have TSTs on my trailer and they work (had the tireminder system but it failed the first trip)

Here's the requirements...

49 CFR Part 571

Tire Pressure Monitoring Final Rule

. Vehicles Covered

The agency proposed to require TPMSs on passenger cars, multipurpose passenger vehicles, trucks, and buses with a GVWR of 4,536 kilograms (10,000 pounds) or less. The agency did not propose to require TPMSs on motorcycles, trailers, or low speed vehicles, or on medium (10,001 -- 26,000 pounds GVWR) vehicles, or heavy (greater than 26,000 pounds GVWR) vehicles for reasons explained in the NPRM.

The Alliance recommended that the agency limit the applicability of the standard to these types of vehicles to those having a GVWR of 3,856 kilograms (8,500 pounds or less). The Alliance stated that the majority of vehicles above 8,500 pounds GVWR are used commercially. The Alliance argued that those vehicles are maintained on a regular basis and do not need a TPMS to assist in maintaining proper inflation pressure in the vehicles' tires.

The Alliance also recommended that the agency explicitly exclude incomplete vehicles, i.e., vehicles that are built in more than one stage, from the standard. Normally, the first-stage vehicle manufacturer is responsible for certifying that all vehicle systems that are not directly modified by subsequent-stage manufacturers meet all Federal motor vehicle safety standards. The Alliance stated that in the case of direct TPMSs, the first-stage manufacturer will be unable to guarantee that, even if physically undisturbed, a non-defective TPMS will function as designed after vehicle modifications (such as adding metal hardware to the vehicle or lengthening its wheelbase) are made by subsequent-stage manufacturers.

Advocates recommended that the agency expand the application of the standard to include medium (10,001 -- 26,000 pounds GVWR) and heavy (over 26,000 pounds) trucks and buses. Advocates stated that tire under-inflation is a pervasive problem with these vehicles, especially given the high percentage of these vehicles that are equipped with re-treaded tires.

TST 507 Flow Thru -

[f5moab]

And TST is great to work with. I ordered the flow thru sensors and they would not fit on my wheels. He exchanged them immediately for the standard sensor. Had them over a year and they have never failed to work (not true of the Tireminder system I first tried). Just changed the batteries in mine last week...and within a minute all were displaying on the screen.
