Thanks to whoever mentioned tire tiers, It made me do some research on the subject. What I gleaned from reading the following websites is; tire tiers are basically established on initial price, mileage expectations, and market. Tire quality and workmanship does not appear to be a qualifier. http://www.moderntiredealer.com/blogpost/b-o-b/340110/what-s-in-a-tier-who-knows by Bob Ulrich http://www.moderntiredealer.com/article/312245/what-is-a-tier-two-tire-tier-three by Bob Ulrich http://fleetowner.com/management/feature/fleet_tire_gamble by David Cullen Those are just a few of the search results:"differences between tier 1, tier 2 and tier 3 tires." Michelin and other major tire mfgrs. say some tires they make overseas does not have a USDOT number because they did not design that tire for the U.S. market. All tires made for the U.S.A. market will have a DOT number on them. Roger am I viewing this correctly?

Roger, starting with the last of your reply first, The entire metal valve stem was replaced. The tire shop said the aluminum rims used their own design and the gasket was not replaceable, the steel rims were different, gaskets were replaced on them. Sailun S637 truck tires are available nationwide today. The tire shop I patronize is one of a small midwest chain, however most truck stops carry Sailun truck tires today. They are all-steel construction, they do not have a limited lifetime mfgr. tread warranty. reviews on simpletire.com Here is one tire thread on escapees.com about Sailun S637 tires dated 2016. I did discover something that mildly upsets me after I got home. Sailun truck tires are now made in Vietnam, under the same ISO and USDOT standards used in China. It brought back memories better left in the past. I will say they ride well, an improvement over the 9 yr old Goodyear G670's that I realize were hardened by age. Only time and rolling experience will tell me more about these tires. I may discover I should have bought the Firestone FS561 LR L tires; at the least I will be a test-case for running Sailun truck tires instead of a top-tier tire.

I apologize men, I've been mainly focused on caring for my wife and trying to maintain our farm. Anyway, I decided on Sailun S637 all-position truck tires. The Firestone FS 560 were a discontinued tire, replaced with FS561. The load range L tires would have been too much for my GVWR of 31,000#, and caused a very harsh ride unless deflated to an unsafe level, plus excessive sidewall flex=more tire heat, which is the main enemy of tires. The 6 Sailun S637 load range H tires were $1,930 final bill. I had a 4 wheel alignment done on the MH last Thursday. Toe-in was .53" more than double Spartan specs., and thrust was out .34". My old Goodyear tires wore-well considering the alignment corrections necessary. The alignment cost was $300, but by the time I drove to Indianapolis(next-nearest truck shop), fuel cost+alignment would've added up to nearly the same money.

I"ve made my decision and new tires are on MH.

As stephikroll said, Winnebago still makes these cables. I had Camping World replace mine-twice, then my extended service contract provider determined the valves were actually bad, as I maintained, and authorized new valves installed too. If you look up your model coach on the Winnebago website you'll find the plumbing schematic for your MH.

Our MH is a 2000, with a 125G fuel tank. When I purchased it in 2013, it had been parked in a barn for 6 years. I've never had a fuel issue - yet. I do full the tank if the MH is not being used for a few months to reduce condensation. Don't be hesitant to use your fuel below 1/4 tank for water concern, everything in the tank is shaken thoroughly as you drive today's neglected highways. The only reason I never get below 1/4 tank is the APU fuel pickup is near that point. Diesel Kleen Clear-Diesel is advertised as a fuel & tank cleaner. I've never used this product, nor do I understand how it can perform as advertised.

Cummins Filtration sells a OCV oil filtration system that captures and returns oil to the engine. When I first read the pdf I was concerned about the "increase crankcase pressure" statement, but near the bottom of the pdf it states the pressure increase, the highest of which is 11" water column/near 1/2 lb. pressure.

My first reaction was, OK Ray that was really brilliant_. I do think UV rays had an effect, they were yellowed.

It was a used MH. You may read all about it on irv2.com, it was over a year ago.Just use the search button for "dropped valves".

Could be, I replaced mine in 2015, they were 15 years old when one cracked because I dusted off a floor mat by swinging it against the front tire.

My mechanic (FMCA member) told me to remove my chrome covers that hid the hub-caps, because when hidden you seldom check the oil level, with the covers removed you see them every time you enter/exit the MH.

One of the irv2.com members bought a newer MH with the 650HP Cummins. Three months after purchase #6 cylinder dropped the valves, total bill was $29,xxx, of which Cummins paid $10,000, the remaining $19,000 came out of his pocket. He said he was offered an extended service contract and declined. Adding insult to injury it happened again later. I bought an extended service contract when we purchased our 2000 Winnebago Ultimate Freedom in 2013. The ESC cost $4,000 for 3 years but since the MH had no records we thought it wise to purchase the Camping World ESC; which was $50 deductible for each work order written at CW repair shop, not each covered line item. By the end of the 3 years the ESC paid for the initial cost + my deductibles I paid. None of my claims were ever denied, and no claim was for the chassis portion of the MH./or work order. Since then CW revised their coverage maximum to 7 yr old RV's instead of 18. IMO it's somewhat like buying health insurance, you hope you never need it, but if you do you're satisfied with your purchase.

TST allows the user to set high/low parameters for air pressure alarms. I have my unit set for 10% low alarm, 20% high alarm relative to my set air pressure. The tire temperature alarm lowest setting is 158*F, and is what TST recommends, they say high temperature tire failures usually occur above 200*F (can't remember the exact temperature). I made the decision to use 10% lower than set tire pressure because of the 20% low = run flat advice. Thanks for the advice about my (130 psi rated) aluminum rims, the hot temperature of my tires causes my front tire pressure to reach 137 psi.(thus my 20% high decision) causing me concern. I know tires are built to withstand pressures over the cold pressure on the sidewall but wasn't sure about rims. The rise of my front tires from cold temperature pressure of 115 to 137 hot seems excessive to me. It might be because whoever added air prior to my ownership did not use a moisture trap on the air compressor; I always use a moisture trap on my air hose.

I've been pricing new 275/70R22.5, LR H all-position tires. So far the best pricing I've found has been local dealers. a small independent tire shop in the city is enrolled in the FMCA tire program. The manager also said he sells Firestone, and quoted me $$2,478.20 for 6 FS560, total price including taxes, mounting, balancing. Quoted $2,580.20 for 6 FS561, which are load range L, whereas my owners manual calls for load range H. I hesitant to buy the LR L because the sidewall may be too stiff/rigid, and result in a log-wagon ride. Which do you recommend? FWIW,my MH is 1,8xx# under GVWR of 31,000# as we travel.

August 3, I was having a valve stem replaced in my truck tire. While talking with the tire store manager about buying new MH tires, he said I would probably not be able to sell my 9yr old take-offs because Indiana DOT was cracking down on commercial vehicles running tires over 10 years old-from date-code on tire. He also said he stopped buying used truck/MH tires over 5 yrs old for that reason, and-no re-sale value. Aug 17; UPDATE: I phoned my retired state policeman cousin and asked him about that 10 yr thing. He said BS, do you really think anyone is going to lay on the ground and try to read a date code that is inside the duals?

I don't know if this pdf will be of help, but It's just one of my downloads for the W keyless entry system. My W owners manual has programming instructions for the TriMark system. There is a lot of information about the TriMark system on the internet. Here is another pdf. that includes programming instructions for a 2004 Vectra/Horizion. My OEM had to be replaced with the replacement system by Camping World, who BTW did an excellent job.

Remove that tire sensor and re-check the air pressure. I once encountered low pressure readings on one tire, I removed the flow-thru sensor and check pressure again, it was normal the last reading. Turned out the sensor was not pushing in the tire valve stem enough to obtain a proper reading, nor would it allow adding air to that tire. Tireman9, back when I was in high school I worked one summer changing truck tires at my uncle's garage, but was never allowed to air them up after I mounted one. An older experienced man did that using a cage made from 2" pipe. Well, one burst, the man lost a hand. Still today, I'm somewhat paranoid about topping my MH tires off before leaving home. Air/gas pressure can be deadly, that's why pressure vessels are tested with water pressure. If one of my MH tires drops to 58 psi, it will remain there until I reach someplace that sells/installs new tires.

Excellent article Roger! My TST system is a bit different, but in the ballpark of your settings. The MOP + 15% is reasonable and logical. I have a question; my front tires are aired to 115 psi, during summertime driving it is not unusual to see operating temperatures of 135-137*F, my aluminum rims are rated for 130 psi, is this cause for concern?

That poses the question, why then does Michelin state if tires are inspected annually after the 5 year mark, they may continue to be used until 10 years?

I plan to install Sailun truck tires on our MH when DW is able to travel again. If you wish to check up on them this is your size. Sailun is a popular tire in Canada, and is becoming known in the U.S.A. now. I notice many HDT's at truck stops running them. I replaced my 5er tires with sailun load range G tires and eliminated my tires worries, never had another tire failure.

Received my magazine today, the way some articles are written, allowing towables is a done deal. The editor could respect the membership enough to wait for voting results.

Cecil hasn't updated his blog since 2012. I'm going to attempt to send him a PM through irv2.com if I can locate one of his posts there. The last email I received from him Willa had passed, and he wasn't doing well. Another version http://seajaythesailorman.blogspot.com/feeds/posts/default

For some unknown reason serial # 785079FB of my 1999 Norcold 1200LRIM is not included in the recall.When I entered my S# on the lawsuit page it said "not included". In order to increase protection against a potential fire, I have installed an ARP unit. This recap of the entire Norcold debacle is quite informative, and disheartening-if one wishes to take the time to read the entire webpage. What really stumps me is, Norcold has not changed the design of the cooling unit, nor have plans to change, according to a man on irv2.com who phoned Thetford and asked, then posted the reply.

I had to cancel our Indy reservation. DW is not healing as Dr.forecast. That cost me over $300 in lost fees, but DW's health is foremost. I considered what someone said about "corporate attorney"- load/inflation charts and their statement about inflating to federal tire placard pressure. Appears to me they covered their 6 for both positions. I remember the Ford Explorer low tire pressure/roll-over issue. I will continue to follow the federal tire pressure placard, just as I do for my pickup and DW's Jeep(wonder how many use a load/inflation chart for pickups or autos?) Following a load/inflation chart figure means you're running tires at their maximum weight limit, airing to +10% means you're running tires 10% over their maximum weight limit. We both know as sidewall flex increases so does flex generated heat. Goodyear says " IMPORTANT: It's a common practice for RV owners to lower tire pressure in their search for a smoother ride. This is not only dangerous, it's relatively ineffective, as the difference in ride quality is not significant. When minimum inflation pressure requirements are not met, tire durability and optimum operating conditions are compromised. Tire inflation pressure should always meet at least the minimum guidelines for vehicle weight." To my knowledge, Goodyear is the only mfgr. that makes an RV specific tire and so states on the tire. Michelin makes truck tires and publishes a RV load/inflation chart. Is my thinking correct on that?

The subject of cost generally rules. The assist program is important to all members, myself included,(joined April '17). Rather than turn FMCA into a clone of Good Sam club by allowing towables, I would not object to FMCA raising dues to $100/yr in order to keep the Assist program, just look at the stand-alone medical assist companies available and their cost per year. I joined FMCA for the experience of being with MH owners. I joined the S.M.A.R.T. organization for the experience of camping and traveling with current or former military members. I joined Good Sam for the overall experience of being an RV'er with folks of all ages.
