  1. So fagnaml have you contacted TireMinder? We would be interested to learn what they said or did.
  2. Yes dimensions and tire to tire clearance are important but so is the load capacity yet no one mentioned the load capacity. Lets look at load capacity & dimensions. Your OE 255/80R22.5 had dimensions of 10. 4 wide and 38.84 OD on 7.5 wide rim LR-G gave you 5205 / 4805 Lbs S/Dual load capacity Min dual spacing was 11.30 I have a post on my blog on Min Dual Spacing and here is a graphic of that spacing There are 265/75R22.5 tires with the same load capacity as your 255 The dimensions are 10.31 width 38.43 OD and 11.61 min spacing so these should fit as you only loose .0.31" clearance and support the load as LR-G tires
  3. Alliguru OK to be clear the hole in your wheel is larger than 0.42 and is closer 0.52 (there are only 2 sizes in that range and we don't need to measure to 0.001". Your picture was good. Well lit and nice focus I added the measuring point on the grommet to your picture so we are both talking about the same spot. NAPA has what you need for $6. Part #: NTH 90431 I would not use the Nylon adapters as you need the softer rubber grommets that will adapt to the small variations in hole size and seal against the stem threads when you tighten the nuts, FYI I have a couple of posts on my RV Tire Safety blog with more details. https://www.rvtiresafety.net/2013/01/what-valve-should-you-use.html https://www.rvtiresafety.net/2017/07/care-and-feeding-of-your-valve-stems.html The aluminum nuts on your TPMS have a spec of 62 In-Lb NOT FT-LB so "snug with a small wrench should do it. Due to the tendency of the aluminum nuts to corrode, I recommend a small dab of Never-Seize on the aluminum threads Your GMC dealer can confirm the torque specs for aluminum TPMS but here is a chart, https://shop.myerstiresupply.com/ERP2Web49/documents/pdf/DVTDynamicTPMSAppGuide2016.pdf
  4. There are only 2 hole diameters for the Automotive market. 0.445 and 0,618 I haven't seen that exact valve but many times the metal threads are the smaller standard and metal valves are sold with 2 different rubber grommets One to fit the .445 hole and one to fit the .618. Without seeing your TPM with the shoulder nut off the stem I can't be 100% certain. You can email me directly and we can work out a "Fix" tireman9@gmail.com I will post the answer here later
  5. If you go to Discounts, then to Michelin, when on Michelin go to How It Works. There you can find dealer locator.
  6. Have you contacted TireMinder directly? If taking the monitor to the sensor doesn't give a reading then yes the sensor may be dead. I have posted a recommendation on my blog that we all test our TPMS at least once a year. This will confirm the pressure when the sensor gives a warning and conforms that each sensor is working as expected.
  7. Here is a good worksheet for those checking the tire position weights. It covers all types of RVs. https://fifthwheelst.com/documents/BridgestoneWeighForm.pdf
  8. What prices were you quoted when you called around? Different locations seem to respond to market pressure so the price in one location is not necessarily the same in another part of the country. This labor rate is not standardized by the tire companies.
  9. You didn't mention your current tire size. Are they 16" ST type? one option is to check out the "Commercial not ST type" 17.5" wheels & tires that can provide increased load capacity which should result in some improved reliability. You will need to look at your actual scale weight numbers and compare with the tire load capacities. For 5th wheel RVs I suggest that the tires provide at lease a 15% load capacity margin if possible.
  10. If you have been happy with your current Hankooks why are you shopping for different brand? Tire prices can vary across the country and tire companies are adjusting prices every few months so I suggest you get the current price for replacing your Hankooks and then check the alternates you are considering when using the FMCA discount. You are the only one that can include the cost of travel (if needed) to get your tires replaced. One other thing to take into consideration is the cost of disposal of your old tires. Some stores charge a different price than others. I wrote a post on "selling old tires" that could offset some of the new tire cost and would eliminate the old tire "disposal" charge. This could amount to a couple hundred dollars difference. When I replaced the tires on my Class-C I sold my 8 year old 16" tires for $300 on Craigslist.
  11. 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.
  12. 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.
  13. 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.
  14. 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.
