  1. I think the better way to specify a lug nut is the size of the socket that fits the nut and the size and threads per inch on the stud. Any auto parts store can help you confirm those dimensions if you take in a lug nut, I would also think that appropriate lug nuts with a SS cover should be available from the Auto Parts stores. I doubt that they are unique to the wheel simulators you have.

    Needing New Tires

    Didn't your TPMS sound a warning? If not I suggest you confirm the low pressure alarm level (no lower than 5 psi below the minimum inflation needed to support the measured load on the tires. You can fail a tire in just a few minutes of operation at extreme low inflation. BUT Just parking on a flat tire with steel body cords can "kink" the steel so that when inflated and driving down the road the "kink" is a stress riser and the "Zipper" can start.

    Needing New Tires

    "Zippering" is the name for the failure mode when steel body tires are run with very low inflation (-20% or lower). You can get this failure on any brand Steel body tire. I suggest you get a TPMS which can warn you of air loss and with the cost of your size tires a single warning can pay for the TPMS system. Here is a post from my RV Tire Safety blog with a picture of such a failure. There is a link to an article on Zipper failures in my post too.
  4. If you change brand or size just be sure the replacements carry equal or greater load capacity.
  5. Yup go to a dealer of that brand tire where they can inspect to confirm the "damage" is only cosmetic or structural.
  6. Sorry folks. Looks like I fell down on the job of monitoring this forum. RE: [email protected] the OP. The wear is not "Damage" but is what is called River Wear. There was a similar post on an RV forum and it is a wear pattern that can occur on non-drive positions. According to the Tire Maintenance Counsel Division of The American Trucking Association "Radial Tire Conditions Analysis Guide" It is called "Erosion/River/Channel wear" It' appearance is Circumferential wear along rib edges next to a major groove. The "Cause" A slow wear rate on free rolling axles. It may vary with individual tread designs. They say "Erosion wear should not be of concern" You could try reversing the direction of rotation by swapping tire position or place the tires on a drive position. This condition is not covered in the link that RAYIN shared but is covered in the TMC Radial Tire Conditions Analysis Guide You can order a copy HERE. It is a bit pricy for non-tire engineer but at over 140 pages it covers just about any tire condition you might run into.

    DOT serial

    Thanks. Yes ALL tires sold are suppose to be registered so the owner can me notified if there is a recall. BUT many do not bother. I covered the topic of Registration in THIS post. The post includes links to allow you to register your own tires or to send new contact information.

    DOT serial

    Some comments on DOT date code. re "oval" Tire mfg use different methods of changing the aluminum"plug" in their molds for the "date code". Not all use an oval plug. Some have used stamped steel strip or "tin" so it can have a different appearance. Some things that is true about all DOT serial The code comes AFTER the symbol DOT by law The first 2 characters are a plant code. the next 2 are a size code. The last 4 numbers are the date code. The serial may have as few as 8 characters and as many as 13 with most having 12 or 13. The date part of the serial only is required on ONE SIDE so may not be on the curb side but facing in toward the coach. My advice is to find the code and record it when it is convenient to you. Nice weather day. If needed i have suggested a $5 or $10 bill and a flashlight and a 10 year old to craul under the coach if needed. Remember you may need to "roll" the RV forward or back a few feet to get the serial in a position that the 10 year old can see it. Keep the full serial with your other important part numbers as you never know when you will need this information.
  9. People need to be very careful when switching tire type from ST to LT as you will need to go up in size or up in Load Range (inflation), or both to carry the load. It is also important to have a MINIMUM of 10% Reserve Load (Capacity over measured load) with 15% to 20% better.
  10. My interpretation is that it is basically a tire with a TPMS sensor attached to the inside of the tire.
  11. "What is the Best Tire" is a little like Chevy vs Ford or Coke vs Pepsi as long as you stick with Tier 1 and 2 I would include availability of company stores that can provide service. Mail-order can save you money up front but offering service can easily be more important.
  12. Been using Surge Guard 30A unit for 3 years. It has warned me a couple times of miswired power pedestal. last week on my way from Ohio to Gillette I used the Surge Guard the first night with no problem. The second night it went through its normal check and all was OK, but when I connected the RV plug I had no power in the RV! Did this a couple times but never got power to the RV. I pulled the Surge Guard out of the system and plugged the RV directly and all was OK. I could not figure out why I could not plug the RV cord into the Surge Guard. For the rest of the trip I was able to plug things in normally with the Surge Guard in the system. I figure there is a relay and switch inside the Surge Guard and the switch is failing. Is the Surge Guard rebuild-able?
  13. Be careful with "beads". Some tire companies may VOID the warranty if they learn you have used something inside the tire.
  14. Visual of the inside of a tire may reveal something you do not see on the outside of a tire when mounted B U T you are still not seeing the critical location of a tire which for radials is inside the structure at the outer ends of the steel belts. Unless you have specialized inspection equipment ($$$$$$$$$) you can't "see" the location of interest. Based on years of experience 10 years is the MAX for tire use as the odds are against you.
  15. You will find that with a few exceptions from Michelin almost all tires (LT and commercial) have the same load capacity when inflated to the same inflation.
