Tag tire pressure

Yahoo Message Number: 13716
Hi all,

Interesting posts on tire pressure. One member stated he put 100psi in the tag but he also stated he used the tire/weight presssure tables. Well, if you follow the tables the pressure could go down below 70 psi (not my recommendation). But, the question is, how much pressure for the tag when it's individual wheel weight is really off the chart (low)? And, what is the basis for your recommendation? My tag wheels are 4100 lbs each and I use 85 psi but without a very definitive reason. What think you? Lyle,

Leaving the current debate on lawyers and tire pressure aside for the moment, I am interested in how various members have been determing how much tire pressure to carry in the tag axle tires. My 04 intrigue weighs in at only 4100 lbs on each tag tire. To use the tire inflation charts would be foolish as the chart would indicate a pressure so low that it is in fact off the charts, on the low side.
So, do you carry the same pressure as the duals or just wing it? And, please, if you have just be winging it don't be embarassed to say so.
Some guidance from coach and tire manufacturers in this area would be indicated by a lot of "don't know" responses.

How about going by the manufacturer's recommendations posted in your coach?

Per,

Thanks for the response and question. My answer is, because I have not been able to detect any logic to the manufacuter's recommendations posted in my coach. What I am looking for is a logical, understandable method for determining tag tire pressure. If you have some please share it.

Help!After installing US Gear in our coach, we have lost all gauges except the air pressure, fuel, water temp, and alternator but including the Cat readout. Checked all fuses and th ey look O.K. George Desmet 2000 Affinity

Perhaps the logis goes back to real road experience.
Consider what happens if you go over a bump. A speed bump is an extreme example, but it serves the purpose.
When the drive axle goes over the bump, the tag axle is pretty much unloaded, since the drive axle is lifted 3-4 inches by the bump. When the tag goes over the bump, the drive wheels are similarly unloaded, and a much greater load is momentarily placed on the tag.
Low pressure in the tag will cause extreme flex of the tag tires if the pressures are low, which is detrimental to the tires. When you weigh the coach, you only get a static reading. If you coould determine the load on each axle while on the road, you would find loads are constantly changing.
Also, for those who reduce tire pressures: If you blow a tire on the drive axle, the remaining tire needs to carry the load. I personally blew a tire on the way to Moultrie, and I drove a couple of miles before I realized the tire (inside driver's side) had gone.
With low tire pressure in the good tire, it may not have carried the load.

Mike,

Did Les Schwab ever give a good reason for their advise or do we just take it for granted?
Per,

I like your logic. I had not thought about dynamic vs. static conditions. What you say makes sense so I will think a little more about it. It may also make sense in the situations you describe to carry more air in the tag than in the drive tires. Even though the increased load on the tag will usually be of short duration (speed bump example) there could be a situation where you lose one of your duals and therefore the load on the tag would be much greater for an extended period. Thanks for the input.
