  1. If something gets in the core the only "fix" is to replace the core itself. There is no opening between the stem and core like n a water faucet so drying to clear the dust by removing the core will not work. Re over tightening the core. Spec is 2 to 5 in-Oz. I just tested a neat tool from SLIME. A Torque limiting tool. $5 at Autozone. I tested it and it "clicks" and releases at 3.5 in-oz. Will be posting on my blog soon as a tool I "Endorse".
  2. I like your approach. Until you get actual individual tire position weights you should be good.

    New Tire Questions

    Yes in the "old bias tire days" the number of body piles would increase with an increase in "ply rating" i.e. Load Range. One main difference between Sailun and Firestone is there is no dealer network with tires in stock for Sailun. Yes in general more flex does generate more heat IN THE SAME TIRE. Without data I don't know how we can make a comparison between different tires especially across manufacturers.
  4. I have a number of posts on valves and valve cores in my blog. Too much to re-post here. BUT Yes valve cores can stick open and it may be possible the TPMS holding the core open may have contributed to this issue. Just get some new cores at any auto parts store. Don't over-tighten. Read this post on how tight is tight enough. 3/4 turn after air leak stops. Use a metal valve cap with an internal gasket if not running your TPMS.
  5. Interesting report that basically says passenger and Light truck tires should be removed from service before year 7. RE the observation on the "death and injury" chart is only reporting total number not the rate. Without the sales number making a conclusion can be very misleading.

    New Tire Questions

    Where are you finding the information on "heavier" sidewalls? Higher Load Range can be achieved in a number of different ways. Without seeing the actual specification and actual test results and an actual tire section there are just too many assumptions being made. I once was able to "upgrade" a LR-D to a LR-E in LT type tire with only a change in the bead wire.

    You only "gain" anything from going up in LR is when you increase the inflation. It is the air pressure that supports the load not the tire construction.
  8. If you leave your tire load on your tires, I suggest you inflate to the tires to the inflation number molded on the tire sidewall. This will lower the bulge of the sidewall and decrease the "flat-spotting" of the tread.
  9. Commercial tire dealer may not understand RVs. Get on a CAT scale. Assume one axle end has 53% of the total axle load and use Load/Inflation tables to learn your Cold Inflation Pressure. Get the tire to a Herculese tire dealer and get it inspected. Tires should not have bubbles in sidewall.

    Tire wear question

    Can't really see tire wear in that picture BUT do the two tires measure the same OD? (OC is easier to measure once off the trailer.) If OC is more than 1/4" different you MUST have the larger tire inspected ASAP for possible belt problems. here is more info on that https://www.rvtiresafety.net/2018/05/st-tire-belt-separation-autopsy-how-to.html

    Tire PSI

    Here is the Double Coin Load charts. http://www.doublecointires.com/wp-content/uploads/Double-Coin-TBR-Data-Book.pdf While I didn't check all the numbers I believe you will see they match all other tire company tires of same size & LR except for a few Michelin tires that are sometimes different by 5 psi or have load capacity difference of a few hundred pounds. When an RV size tire is made the tire company doesn't know what vehicle it is going on. Only time a tire company knows that info is for regular production cars and smaller trucks. Load charts have been around for more than 50 years so the tire companies know how to make tires to perform to those. Getting on a truck scale to learn your actual axle loads is easy, Low cost (I believe less than $20). At FMCA Conventions RVSEF offers a real service to measure each tire position as very few RV have 50/50 side to side laod split which is the assumption for the 80psi on the Federal stickers. I would support 90 - 95 until you get individual position scale weights. Be sure you have a 15% Reserve Load capacity above your ACTUAL heaviest end per axle. if possible. Get and run TPMS and be sure it is programed correctly.
  12. All tires have "Made In xxxx" molded on the sidewall so no need for bar code translation.
  13. Well the "SmartWay" program is a reasonable way of comparing fuel efficiency of tires. There are specific performance standards a tire has to meet to get the rating. In general you can compare across brands as the "Big Guys" will display that Logo in their literature if it meets the standards. A claim for "better fuel economy" without the SmartWay logo is what you call propaganda. I believe that when you look at same size, Load Range and type (Rib vs Rib or Traction Vs Traction ) you can figure similar fuel economy. If you go to the Goodyear web site The Endurance LHS is not included in the Goodyear RV tire data book. It is on pg 14 of the GY Commercial tire Data Book under "Long haul" It does show SmartWay but as a "Long Haul" it may not deliver equal MPG as an "RV" tire which are normally considered Regional. You would need to talk with someone at GY Commercial truck tires
  14. "more fuel efficient" than what tire? Do they carry the EPA "Smart way" seal?
