Dual Tire Pressure Equalization System

So is anybody using a Dual Tire Pressure Equalization System?
and if so what brand are you using?
looking for a better way for my dually, as trying to check the pressure on the rear tires is a pain
thanks

I debated these for a while but ultimately ended with the feeling that I didn't put enough miles on the truck to justify it.

Instead, I opted for a TPMS from TST so that I can know what all 6 truck tires are at a glance.

When it's time to air up the tires, I use a straight dual-head air chuck and the same for a digital tire pressure gauge (straight dual-head).

The biggest thing- when I have the tires rotated or any shop does work to remove the wheels, I make sure to tell them to ensure that the inner dual valve stem lines up with a hole in the rim so that my tools reach through.

As a career mechanic I find it sad you need to tell them that. Hang the first tire, it takes literally no time to set the outer valve stem opposite the inner valve stem and hang the outer wheel.

You know what they say about signs and warnings... they're there for a reason.

That one or two times that I didn't, I paid the price for it.

As a tire engineer I see little to no advantage and some definite downside with the tire equalization gizmos.

If/when you get a puncture or leak in one tire BOTH tires will have the air pressure reduced till the limit is reached then one tire will continue to leak. Now you have an underinflated tire being 100% overloaded. This can lead to damage that may result on both tires ultimately failing.

The gizmos do not provide timely warning. You can still drive hundreds of miles before you stop and check tire inflation. At that point it is too late. BOTH tires will be scrap.

TPMS will provide timely warning to the driver on low air pressure.

If you are having problems getting to your valves to inflate or install TPMS simply use the appropriate hose extenders with the outer end firmly attached (pop rivet) as seen below.


When inflating tires be sure to support the hose when pressing the air chuck to end of hose so not to over stress the rivets or hose mount.

I have over 30k miles on above and similar with no problems.
I got my hoses on Amazon.

Do you have a recommendation on TPMS system for dual wheel trailer? They don't interfere with vehicle system or navigation system wifi, do they? We have a 2011 Wildwood and just bought a 2016 Ford F150 4x4 Lariat. Thanks in advance for any tips!

In my experience of several years running a dually, the tire equilization accessory defeats one of the advantages of duals. If one goes flat ... they both will. On two occasions I had one of the duals go flat ... one due to a valve stem and one a screw. I was able to continue on at a reduced speed to a more convenient place to fix the flat. If I had had the equilizers added I would have been sitting right where it all started and neither place was pretty.

I bought a TPMS back before I started writing my blog. I have Tire Trakker and like the Lifetime warranty, user replaceable sensor batteries. Battery operated monitor and especially the Early warning from the "Rapid" air loss.

Full disclosure. They sponsor the blog I write, but since I do not own the blog (I write for the blog owner RVTravel.com) I receive zero income and no commission from any sponsorship or sales of TPMS.

I do have a post on "Best TPMS" where I identify the features I think should be considered before purchase. There is no single brand or type TPMS that is "Best" for everyone as we all have different wants and needs.

I use crossfire, when tire pressure drops 10 psi valve closes so both tires don't go flat as some people have stated earlier. After the numerous posts where people with TPMS had blowouts with out warning I thought the extra money was not worth it IMHO. To each their own, I have only had them on for 6 months so no long term experience yet. Good Luck!
