  1. I would still get on a truck scale and ensure the new tires can support 110% of the measured load based on heavier end of each axle. If you can't get individual ends at least assume 52% of the axle reading. In 2017 RVIA changes the tire requirement to be able to support 110% of the GAWR. This was done to at least partially address the known tire overloading seen on a majority of RVs. You can meet the 110% either with higher Load Range and higher inflation or with larger tires.
  2. In addition to finding the OE size and Load Range i suggest you also get the unit on a truck scale to learn how close to the GAW rating your RV is. HAve you looked for a Holiday Rambler forum? You amy be able to find someone with your exact model and year who can point you to the location of your Certification label that has all kinds of important weight and tire information.
  3. Comment: As with many such articles many people simply collect information from various sources on the internet and write a post for publication. This is a source of income for many. The problem is that some times the authors have no personal knowledge on the topic so do not always do a good job of separating the "wheat from the chaff". One telling comment for the drivinvibin site is when they said ST stood for "Special Tire" when in reality ST stands for Special Trailer. 'China Bomb" is a popular but incorrect "title" given to many tires that come on RV trailers. This "reputation" was developed when RV companies focused on buying the cheapest and lowest capacity tires possible and we ended up with almost all trailers coming with tires made in China,. Couple this fact with the reality that most RV trailers are overloading their tires, so when there was a tire failure for any reason (overload, high-speed, under-inflation or even a nail) the RV owner simply decided that it must be the tire's fault and since all tires were coming from China all tire failures occurred on tires made in China, the reason must be because the tires were made in China, Even the punctures or overloaded or under-inflated tires as certainly the RV owner can not be expected to be responsible for any of those conditions. I could just as easily blame the city of Elkhart, Indiana for making poor quality RVs because almost every problem is on an RV that was made in Elkhart Indiana. So should we all boycott RVs made in Elkhart? I also found the article a bit racist as the authors managed to find a picture of a man who is descended from Asia ancestors selling tires in an effort to support their unsupported contention that tires made in china are almost all junk.
  4. When you say they "Look Good" I bet you are just referring to having good tread. You can review tire inspection on this site. https://www.rvtiresafety.net/2014/08/how-do-i-inspect-my-tires.html Some related info. Herman is correct that the tires may be 2020 but you should have the complete DOT serial for each tire recorded as they may not all be the same. Have you been on a truck scale when the RV is fully loaded to the heaviest you ever expect to be? This is important as it is well documented that over half of the RVs on the road have a tire or axle in overload. I also cover load and inflation in many posts on my blog.
  5. Certification sticker location on motorhomes moved around a bit before 2010 or so. You didn't say what year Thor you have. Certification label for motorhomes is suppose to be on driver door jam if there is a driver door. If no driver door then somewhere near the driver left elbow. I have seen on the floor or just behind the seat but start looking there. This means your Thor Chateau 22b should be on driver door jam just as on cars and P/U.

    NHTSA Recall ID Number : 22T009 Synopsis : Goodyear Tire & Rubber Company (Goodyear) is recalling certain G159 tires, size 275/70R22.5 with DOT date codes 046 through 0403. The tread may separate from the tire. Tread separation can cause a loss of vehicle control, increasing the risk of a crash. Dealers will replace the tires installed on recreational vehicles, free of charge, and provide a $60 voucher for the cost of professionally weighing a recreational vehicle. Goodyear will offer a $500 refund for tires not installed on a vehicle. The manufacturer has not yet provided a schedule for recall notification. Owners may contact Goodyear customer service at 1-800-592-3267. ======= Normally a recall only includes tire replacement. The $500 bonus is special. So is the payment to get the weighed. These are older tires (1996 - 2003) too and should have been replaced a years ago.
  7. OK lets step back a bit. I can give you the answer you need but I do need some information from you. 1. What size are the new XZE tires? 2. What is the Load Range letter? (E,F, G etc) 3. Do you have scale weights for each tire position? If not do you have scale readings for each axle? These readings need to be with the RV loaded as heavy as you ever expect to be. This means full of water , fuel, propane, food, tools and clothes and people. We are looking for the heaviest you expect to be. These weights can be with the previous tires or with the new tires 4. Iambullok mentioned the certification sticker. That has some important information A. GAWR fir F and R axle B. tire size including Load Range letter (e, F, G H etc) 5 To be sure you get my answer you can drop me a line at tireman9@gmail.com as there is sometimes a delay of a day or so after a post is made before I get a notice.
  8. Test message trying to update signature
  9. Just logged in again. Checked the Sig under My Profile. It is correct as it says I will be at Tuscon this March. This post is a check. If it says Gillette there is some problem with the program.
  10. Yes I saved the changes. i have tested with 2 different computers. When I go to my profile it has been updated but my posts do not show the change.
  11. I have updated by Signature under my "Profile" but the new sig does not display
  12. Your tire says "Max xx psi at Max Load of yyy Pounds" Will your tire blow up if you go above xx psi? The simple answer is No. Your undamaged tires are not going to Blowout or Explode or Blowup if you see a pressure greater than xx psi on your TPMS or on your hand gauge. There is a lot of confusion out there because people do not understand the reason for the confusing wording that is mandated by DOT. There are Federal regulations on the words and information that must be molded on the tire sidewall. This wording has been around for years with some unchanged since the 1960's. A recent poll of RV owners responding to a question on tire inflation number on the tire sidewall indicates that 18% think the inflation number molded on a tire sidewall number is the absolute highest a tire should ever have in it. Another 18% think that inflation is "the best" inflation for the tire 2% think it's the lowest pressure the tire should ever have. I am very disappointed with this level of confusion. Here is the reality: Each type and size tire and Load Range has a stated Maximum load it should ever be subjected to. The number is molded on the tire sidewall in both pounds and Kg. The tire industry has published tables that provide the MINIMUM inflation a given tire needs to support a stated load. The tables clearly state that the inflation number is the inflation measured before the tire is driven or warmed by direct sunlight. This is called "Cold Inflation". Not "Refrigerated" inflation and not some laboratory 68F or 70F "standard, but the inflation that would be the same as the surrounding ambient air. Some people know this as the "Temperature in the shade". The confusion comes about because until recently vehicle owners never knew the operating temperature and pressure of their tires. However with the introduction of aftermarket TPMS as used by many RV owners, they now have those numbers presented to them. What is missing are two things. One being training by the selling dealer as to what inflation is needed to support the stated load and second an explanation of what the words on the tire actually mean. I am not sure if the RV salesman has ever received the training other than to tell the customer the information is in the Owner's Manual. Hopefully when an RV owner reads "Max Load" they understand that they should never load the tire more than that. The confusion comes with the inclusion of the word Max as it relates to tire pressure. IMO the wording would be much better and more logical if the tire said "Max Load yyyy pounds at xx Psi cold". I would leave it up to the people at DOT to try and explain why they were not consistent across all types of tires with the wording on load and inflation limits, but I have no idea who to ask. as I expect them to pass the question off and say "Ask the tire manufacturer" but the manufacturer is only following the regulations established by DOT. I have covered the topics of Load & Inflation many times in my blog www,RVTireSafety.net you should be able to find the answers to your tire questions there. I have a large number of posts in my blog that mention inflation. If you have questions I can suggest you review my posts as the questions are asked a few different ways and I provide the answer with what I believe is a consistent interpretation of the intent of the requirements.

    10 Tire TPMS

    I have been happy with TireTraker and their new units offer Lifetime warranty
  14. When getting new tires be sure to record the full DOT serial (or snap a picture of each). This eliminates the need to crawl around after they are on the RV. Keep that info with your other important information. If there is a recall you will have the needed info at your fingertips.
