After blowing 3 Marathons on a trip this spring and wiping out the propane lines, I am done with Marathons and have no confidence in the new Endurance made in the USA. Therefore, I am switching from ST235 80 R16 to LT235 85 R16. G rated and 14 ply with a R speed rating made by Goodyear for trucks and 5th wheels in the USA. They are about 1 inch larger in diameter.Google G614! They require 110psi so I crawled under the rig to check the pressure requirement stamped on the rims. They are good for 110psi. My friend bought the same size Road Lux tires made in China at half the price I paid for the Goodyears. I don't trust the China junk and wanted to buy American to keep our people working. Peace of mind comes at a cost but now I can travel without the worries of the tires.
