Tire pressure and fuse location

What tire pressure should I have in my 2001 Affinity with a tag axel? Also does anyone know where the 30 amp fuse for the Thomas compressor is located.

If you haven't weighed it yet then you go by the plackard that shows the tire pressures. It won't be totally correct but better to be too high than too low with tire pressures

Herb,
Mr. D is correct. You really need to weigh your Affinity. Mine weighs 40,000 pounds with a full fuel tank and about half a tank of fresh water and nothing else. No driver, passenger, or junk stored in it at all.
So next time you are at a T/A or Petro etc run it across the CAT scale. Doesn't cost much and is really the way to go to determine correct tire pressure.

Luck,
Bob

Ok, so BlueDog, why didn't you give the OP a starting point?

As to the OP, you can look at the data plate on the coach and it should give the max pressures you need to run. This is a "worst case" basis meaning that you are loaded to the max. On my coach, the pressures are 120 front and 110 in the rear as the max. By weighing the coach, you can fine tune the pressures. Until you can get a coach weight, it is safest to run the pressures listed on the data sheet installed in the coach.

We went to the Country Coach factory last summer and they recommended and put into our 2002 Affinity the pressures that are printed on the panel next to the drivers seat. We had been running about 10 lbs per tire less than that. Our coach drove better after going to the standard pressures. One little special thing about Affinities you should know about (at least 2002 Affinities), is they have special high rated wheels in the front. Normally the wheels are rated to 120 cold pressure. Our Affinity has 130 lbs wheels on the front steer tires. The high rated wheels can be identified if you look closely because they have smaller holes in them than the standard ones.

1. The best answer is to get at least each axle weighed on a scale and use the tire manufacturer's inflation chart by load weight on each tire. Use the same inflation on each tire on the axle.

2. The temporary answer is on the Coach manufacturer's plate which is low on the driver side wall in the cockpit of my old rig. Keep in mind that how you load the rig and the type of tires now on your 11 year old rig may make these recommended pressures less than accurate.

Country Coach installed six new free tires in 2002 on a recall on my then 7 year old rig, because the manufacturer's recommended tire inflation was too low.

They executed a rather major recall in 2001-2002 for tires on various rigs they had sold through 2001 and provided erroneous inflation guidance.

About that time, Toyo Tires published a policy that they did not want their tires installed on Country Coach rigs because of the "errors" in specifying tire size and inflation rates that continued over several years at the Country Coach plant.

All,


From 2006...............may make placards suspect.

Washington, D.C. – Country Coach, one of the nation’s largest manufacturers of Class A motor homes, has launched its fifth recall in seven years to replace the tires on some of its motor homes, blaming the Toyo tire company for outfitting its recreational vehicles with tires unable to carry their weight.
Country Coach, a Junction City, Oregon-based subsidiary of RV Holdings Inc. told NHTSA that Toyo’s M102z models were responsible for more than 50 tire failures since 2003 – a charge that Toyo has strenuously denied. This most recent safety campaign underscores what appears to be an industry-wide problem: RV manufacturers under-rating the axle weight of their vehicles and outfitting them with tires that cannot bear the load, particularly in the left front. In the last several years, at least five manufacturers, including Fleetwood, Newmar, Airstream, Four Winds and National RV Inc., have initiated recalls involving more than a dozen motor home models with incorrect weight or tire pressure ratings.
With government scrutiny increasing, this problem is also pitting tire manufacturers against RV-makers as both try to lay the responsibility for these accidents on each other. In March, Toyo issued a technical bulletin to its dealers sternly advising against outfitting any motor home manufactured by RV Holdings Inc. with a Toyo tire. The bulletin, in part, complains:
In multiple recalls and internal service bulletin campaigns conducted from 1999 to 2005, the manufacturer and the brand-name owner NRVH and CCI have repeatedly failed to warn Toyo about safety problems related to suspension components, and the installation of incorrect tire placards that led to tire failures. Based on this history, Toyo cannot be confident of receiving future communications from NRVH and CCI relating to problems on coaches that have been outfitted with Toyo tires.
In the meantime, RV owners have borne the brunt of these miscalculations in the form of sudden sidewall blowouts on the road. The Country Coach tire failures have mostly resulted in property damage accidents. But in other cases, motor home tire failures have resulted in injuries and fatalities.
Rick Morrison, an attorney with the Montgomery, Alabama based-Beasley Allen law firm is currently litigating two separate cases of left-front tire failures on motor homes manufactured by Monaco and Newmar that have resulted in fatalities.
“As far as I’ve seen, there is no engineering process, no testing, nothing that the RV manufacturers have done to make sure that the tires are appropriate for their vehicles and have the appropriate load-bearing capabilities,” Morrison says.
Some of the recreational vehicles most vulnerable to weight and tire issues are Class A Motor homes, the largest, and usually the most luxuriously appointed RVs on the road. They measure 24-40 feet in length and feature a kitchen, cockpit, living area, a bathroom and a bedroom. Over the years, manufacturers have found a way to maximize the living space with motorized slide-out units. Some models have multiple slide outs. But, as other motor home manufacturers have discovered, slide-out units can also considerable stress on the front tires. In 2004, the Newmar
Corporation initiated a recall covering two of its models that had suffered front tire failures. In 2000, after two fatal accidents, the Fleetwood Corporation recalled the tires on 3,745 of its some of its models. In both cases, the manufacturers increased the load rating and replaced the tires with more robust models. One RV blogger captured the current trend on the enthusiasts’ website Main Menu Page “We keep demanding goodies, i.e. four slide out design is not unusual today. I have had reports of overweight coaches with tires, wheels or some other component failures caused by too much weight. More than one manufacturer has had to do a complete tire recall because of overloading.”
As the Country Coach case demonstrates, outfitting recreational vehicles with the proper tires can become a trial and error process, because some manufacturers have failed to determine the actual weight of a recreational vehicle, loaded with water, furniture and other accessories of motor home living.
Country Coach’s tire problems date back at least to 1999, when some of its models began to suffer tire failures related to what RV-maker claimed was under-inflation. In October of that year, Country Coach announced a recall for certain 1998 and 1999 Allure and Intrigue models with slide-out galleys. Earlier that year, the company had received 12 complaints of steer axle tire failures due to under inflation. Country Coach’s initial remedy addressed the tire tag specifications, which recommended a pressure that was too low for the tire to handle the load leading to a possible failure. It directed consumers to go to a Country Coach dealer for a replacement tag and to have the tires properly inflated to a higher pressure. Two months later, Country Coach determined that the RVs operating on under-inflated tires might have already been damaged and announced that it would replace the front tires of 448 units. According to quarterly reports filed with NHTSA, Country Coach replaced 438 tags and 394 tires.
That recall forced the company to take a closer look at the weight ratings of its motor homes, and in 2000, the company discovered that its Affinity Grande Chalet motor homes had been assigned an inaccurate front axle weight rating. An inspection of all of its products since 1990 uncovered more models with the same problem. In total, 289 1995-1998 Allure and Intrigue motor homes had been similarly misclassified. The vehicles were rated as 9,000, 10,410 and 11,000 pounds, when they should have been rated at 13,200 pounds. This time, Country Coach offered to replace the incorrect tire tags and replace the front tires and rims at no charge.
Later that year, Country Coach told NHTSA that it had found a problem with the weight distribution on its older vehicles. In April, the company issued a service bulletin notifying 994 owners of Allure and Intrigue motor homes-about half of whom were included in the first recall-that they need to change the configuration of the ride height control valve. This time, Country Coach proposed to swap the old ride height control valve design, which consisted of two valves on the front axle and one on the rear axle, with a new design. The original design put too much weight on the front left tire, Country Coach said. The new configuration located one ride height control valve on the front axle and two on the rear axle to more evenly distribute the weight.
In 2002, Country Coach launched a second, bigger recall for a tire under-inflation problem. This second action involved 550 Affinity, Magna and Concept motor homes in model years 1995-2000. Again, the vehicles’ tire tags were incorrect and 301 of them had been assigned incorrect front and rear axle weight ratings. This time, Country Coach offered to replace the tire tags and the tires of all vehicles with incorrect cold inflation pressures and assigned correct axle weight ratings on those that had been miscalculated.
But the overloaded tire problems persisted. From December 2003 to March 2005, 32 of the recalled motor homes suffered one or more tire failures. Another 19, which were not included in the recall but used the same tire, also experienced tire failures. In 2005, NHTSA opened a recall query, after receiving two complaints of front tire failures for motor homes that had already received the reconfigured ride height control valve design. In its reply, Country Coach blamed the tire manufacturer, Toyo. “The root cause of the failure, in CCI’s opinion is overrating of the 275/70R X 22.5 M102Z and M140Z tire’s performance, durability and weight carrying capacities by the manufacturer.”
Toyo, which sold 17, 252 of its 275/70R22.5 Toyo M102Z, H load range in the U.S. between 1996 and 2002, repeatedly denied any defect in its tires and blamed the problem on overloaded vehicles on under-inflated tires.
Neither response satisfied the government. In May, NHTSA received another consumer complaint of a tire failure on one of the recalled vehicles and raised the level of inquiry in July 2005 to an engineering analysis to determine if Country Coach’s remedies were adequate. NHTSA conducted two field surveys as part of it’s investigation, that checked weights and tire pressures on several Country coach models and found motor homes with disproportionate axle loading, overloaded and under-inflated tires, loads that exceeded the vehicles gross axle weight rating and some that remained unrepaired from prior recall campaigns.
Country Coach announced on June 30 that it would initiate a recall to replace the tires, but did not specify which models or model years would be affected.

Just my .02
Luck,
Bob

Yep, tires can be overloaded by the RV manufacturer. Used to be much more common than now.
Our DSDP had a front axle rated at 12,000#'s and tires to match. Found the empty rig (when fuel and propane tanks filled) weighed 12,050 on the front. That made it illegal to be on the road or even sold. Newmar fixed it by having Spartan replace the axle with a 14,600# unit. They also replaced the front standard duty steel wheels with heavy duty steel wheels. I asked about replacing the tires and they said it wasn't needed. I did have to run 120 psi and Michelin rerated (in writing) the tires to use the 125 psi rating with 120 psi in the tires.
After almost 9 years running it that way I did replace the 275/70 tires with 305/70's (and Alcoa wheels all around) and can now use the full 14,600# axle capacity.

So if I go by the placard, I could still be doing it wrong if the placard was not updated.
Is there an easy way to tell if the recall was performed?

I read the response posts to say, that the placard could be meaningless even if updated.

If you're still running Toyo's, the recall wasn't performed. Toyo explicitly says in their notice from 2006 to NOT run any of their tires on Country Coaches. The notice is fairly explicit:

Click this link for Toyo recall notice and advisory:

Effective immediately, Toyo Tire (U.S.A.) Corporation recommends against the installation of any Toyo tire on any model motor home manufactured by National RV Holdings, Inc. (“NRVH”), including Country Coach (“CCI”) and National RV (“NRV”) motor homes.

My fronts had been replaced with Goodyears on my 2003 Lexa, but I still had original Toyos on the rear when I bought it last year. Visible cracking of sidewalls etc., but that's not uncommon on eight year old tires. I'm now running fresh Michelins in all eight positions.

"If you're still running Toyo's, the recall wasn't performed."

I believe the Recall work was done by Country Coach, and they did install 6 new free Toyo tires on my rig and provided me with a new placard to place in the cockpit. Of course those tires would be 10 years old now.

Toyo did not do a recall. But they did finally put out the above notice because they did not get co-operation from CC on the proper application of Toyo tires on newly manufactured rigs.

This all occurred following the Firestone/Ford Explorer rollover issue that was highly publicized.
