Bill & Susan, in the absense of individual weights you have little choice but to go with the maximum. Once you have obtained actual weights you can make another decision. Your ride quality may suffer at max pressure but your safety should be improved.

You need to inflate the tires to the pressure stated on the tire placard in lieu of actual weights. It should be stuck to the console that contains the transmission control and light switches. You might need 120 in the front but I am sure you don't need 120 in the rear.

I have an 04 Inspire and it came from the dealership with low tires. I had a problem finding out the proper air pressure and consequently began wearing the front tires on the edges. I had the fronts exchanged with the two from the rear, and put 110 in the front and 100 in the rear. No more uneven front tire wear. Hope this helps

Congrats on your new coach, I think your going to like it.
You should have tire charts with your Country Coach information that will give you proper pressures for a given load. Until you know your exact load, I think I would "ballpark" it based on the load you think you added to the coach. One thing for sure, if you put in 120#s all around you know your not under inflated, but I think thats overkill.
On my Inspire, I carry 105#s front and 95#s on the duals.
Good luck with your new coach!

We have 2006 Inspire also and just returned from the East Coast Rally. In one of seminars, CC people stated that all tire manuf now require that you carry the stated pressure on the plack next to the driver. They said it has turned into an Ford Explorer issue with low tire pressures. No buts.....

There is a label that states the tire pressures that is located on my coach on the left lanel by the drivers feet. The front tires will have a different(and probably lower) pressure than the front. I would use these pressures as a starting point.

Ray,

I also have an Inspire and keep 102 psi front and 98 psi in the rear. I have had the unit weighed three times and feel comfortable with these pressures. Somewhere in the coach documentation you should find the factory weight data sheet. My factory weight data sheet was located in the file box that was provided with the coach.
That will give some starting data until you can have the coach weighed by wheeh position. My Toyo tire data sheet was located in the coach chasis book. Toyo tire data can also be found on the web.

At Moultrie, GA in spring 2005..... at FMCA, Perry, GA spring 2005 and at last week's East Coast CCI rally the tire manufacturers (Toyo and Goodyear), the tire dealers (Les Schwab), and Country Coach unanimously agree that tires should be inflated to the Federal Gov't mandated placard pasted on the interior coach wall by the driver's left knee..... absolutely no ifs, ands or buts - PERIOD.

By the way, those values are for "cold" tires, where they define "cold" as either 65 or 67 degrees F. Of course the tires will increase pressure as the tire heats up, perhaps to as much as up to 160 or even 180 psi in VERY hot weather and strenuous driving conditions, but they say the tires can handle it.
I inflated mine to placard values six months ago, and have not had to "adjust" pressures ever since. Yep, they read a few pounds high on warm mornings, and climb by 15 pounds or so in moderate temperature driving, but I don't fuss over them.
I find great relief in now "knowing" what the "correct" pressure is.

Joe,

You may see tire temperatures as high as 160 to 180 but pressure should never go that high. For that matter with running the tires at 120 psi the temperature should stay around 150. We have been running Smart Tire for 4 years and even in the desert of Calfornia in the summer our temperatures never went over 160 or pressure over 140 but then we don't drive over 65 mph.

The label on the shift console next to the driver is a good starting point. I would never run lower than that value. You should have a card from the tire mfg in your document box or perhaps you can get a chart from them on their web site; I'd go with the higher of that value or the CC label. My preferance would be to stay at least 5 lbs under the maximum rating of the tire or wheel, though.

However, if you are 'pretty well loaded' you will want to get the actual front and rear axel weight and if possible, side to side weight to ensure that you are not exceeding any weight limit or significantly out of balance.

My 2004's weight wet (full fuel/water/propane but empty of everything else) was 3000 lbs under the max, but unfortunately only 1000 lbs under the rear axel weight. That's going to make it difficult to load 'legally', particularly if I want to tow anything. Note that adding pressure to your tires does not allow you to exceed any weight rating.

Hello All

Went to the CCI rally in Kerrville and had a wonderful time and met several new GOOD friends. When assessing the cost of joining CCI I would suggest that the dues are less than taking four people to the movies with popcorn, and the pleasure of making new friends is priceless.
OK, tires - while in Kerrville we were able to have our coach weighed at each wheel position - something that I have been wanting to do for years. The weights were as follows:
Driver Front 7940 lbs. Passenger Front 7600 Lbs. GAWR 16,600 lbs. Actual 15,540 lbs.
Driver Duals 10,100 lbs. Pass. Duals 10,100 lbs. GAWR 20,000 lbs. Actual 20,200 lbs.
Driver Tag 4650 lbs. Passenger Tag 4950 lbs. GAWR 11,000 lbs. Actual 9600 lbs.
The inflation placard in the coach calls for 125 lbs in the front, 105 lbs in the duals and 85 lbs in the tag. The Michelin inflation tables (without an extra 5 lbs for good luck) call for 115in the front, 85 on the duals and 85 (the lowest pressure that the table goes to) in the tag.
So, the placard is 10 lbs high for the front axle, way over by 20 lbs on the duals and uses the lowest table pressure for the tag. Why such high numbers from CC for the steer and dual axles?
I have been running the placard pressures since new. I have been told by a knowledgeable source that CC had a problem with Toyo tire blowouts (may have been a lawsuit) and therefore the CC attorneys mandated that CC use the highest pressures available for the placards irrespective of the inflation tables from the tire manufacturers. Who knows?
This post is for information purposes only - I am not sure yet if I am going to adjust my pressures downward although I think I am going to do it in the duals - if I do it in the duals and steer axle it will first be to see if there is any appreciable increase in ride quality. I will report back if I make the adjustment.

Kindest Regards,

Brad Burgess

After getting slammed pretty hard over cold tires and hot tire pressure there are three things on this site that will always make you a dart board...politics, religion, air pressure in tires.

Not sure I want to start this, but keeping your tires to within 3 to 5 PSI is not really required. I have Smartire on my coach where you can monitor both both tire pressure and temperature. Quite often on a sunny 70 deg day, there will be 5 psi difference between the sunny and shade side of the coach, after running for an hour. Both tires were the same pressure in the morning ! Based on this item , alone adjusting for 3 psi is clearly excessive. If you follow the FMCA recommended procedure of weighing the coach and then setting 5 to 10 PSI safety factor above that, even losing 5 psi for the altitude issue.I , typically don't add air more than once a year, and I check the pressures and temperatures 2 or 3 times a day when traveling. On 90 to 100 deg days the temp can run to 135 in the tire. This causes pressure build up much greater than the 3 to 5 psi adjustment spoken of. I KNOW, this topic has been beat to death as well, but adjusting for that amount of pressure is a waste of time IMHO
