We have had several diffent rigs in the last two years of fulltiming. In addition we've had experience with both Michelin XPS Ribs and the Goodyear G614's. Both tires have given excellent service, however, you must be careful to use them in the proper application.
We previously had a very heavy TT that came with 15" D load rated tires and rims. We continually had tire problems and upgraded to E Load tires. That didn't work too well because we did not know at the time the rims could NOT support the E load pressure, they were rated at 65lbs and we actually split a rim at the weld (steel rim). We upgraded our rims to 16" steel welded rims and changed to the Michelins and never had another issue and put over 15,000 on them before trading off to the HR Alumascape.
The Alumascape grossed out at 16,900 with 7,000lb axles and came equipped with Goodyear G614 G rated tires and appropriate sized aluminum rims...ran those tires/rims for close to 15,000 and again...NOT ONE PROBLEM! Can't say much for the rest of the HR though!
Now have the Bighorn 3600RL, it unfortunately came with Goldway tires! They are, however, G rated LT tires and so far look good, but we are watching them quite closely!
Our experience is that LT tires of the proper size and load rating for your carried load are the ONLY way to go...In addition, BOTH of the tires mentioned are steel belted SIDEWALLS; this is what gives them the ability to take the stress of flexing when we make severe turns, etc.
We also use pressure pro and make certain we are ALWAYS running the proper tire pressure for the load we are carrying, which is in most cases between 105-100lbs. Good Luck and be safe!
