Dual Tire Pressure Equalizers
I can see the pros, are there any cons to using dual tire pressure equalizers on the rear of a coach?

I had an inside dual blow out...was able to get off the road in a longer distance than would have been allowed with both tires gone.
Last week inside dual went flat due to valve stem. Again I could move the coach because I still had a good tire.
So the con is if one goes flat they both go flat.
Not good, especially at higher speeds.

Tire equalizers
I have 40 years experince with HD trucks. Dual tire equlizers benifit tire wear on duals by making sure booth tires are inflate absolutely equal. In the case of any sudden loss of presure in one tire or a pre set differential they are designed to shut off and you do not loose presure in the good tire.

Thanks for the replies.
Ron D, this is the info I got when I stumbled on them. I think for the cost of tires, $150 for both sides makes a lot of sense. I think I'll go ahead and install.

I have an air pressure gage I think was called"The Octopus". It attaches to both this at the same time. Solves both problems.

Tire equalizers maintain equal pressure between the tires at all times. A tire inflater does not do that.

I was always tempted to get a "Cat's Eye" or other dually equalizer but didn't because I'm not sure how they would marry with a TPMS.
I understand that, if one dual suddenly goes flat, the system will close so that both tires don't lose pressure... but if a single TPMS sensor is monitoring the pressure for the pair of duals, wouldn't this hide the flat dual from the TPMS sensor?

I would think that would be the case. I suppose you'd have to "T" the pressure sensor at each tire before the equalizer, so the sensor can read each individual tire pressure.
I understand how the equalizer can close off based on a pressure difference after a blowout. But what if there is a slow pressure leak, such as one tire running over a small nail. As the one tire slowly deflates, won't it take the other tire down with it? This may be less of a concern with a TPMS, but seems like it might be an issue if you didn't have one?

Equalizers have been proven over millions of miles on HD truck fleets. I have fourty years experince in this industry. If you want facts visit a HD tuck tire ditributor taht sells them and services major over the road fleets.
