Michelin XPS rib or Goodyear G614

Pulling a triple axle XLR Thunderbolt 40X12. Want to pull the Power King tires off and put either the Goodyear G614 or the Michelin XPS rib. I like the idea 14 ply of the goodyear, but have read they have some problems with blow outs.but also read they have addressed those issues. Have read good things about the Michelin's. Camping this weekend so gonna make a move next couple of days. so here we go.

  • Actually the ribs are cheaper than the G614

    It can be a catch 22.

    • Goodyear G614 - yes some reported blowouts read about on here, but Goodyear is good about picking up the repair bill.

    • Michelin XPS Rib - only heard of one blowout on RV.net, but he got the finger from Michelin for repair beyond the tire.


    I've had two sets of G614. I ran the first pair 4 years but not a lot of mileage, and sold the unit. These are brand new. I have not had a ton of experience with them, but I have not had any problems either.
  • After doing research and reading the RV blogs for several months, the top rated were the Michelin XPS Ribs for durability, less tread separation or blowouts. Most RVers indicated they had less tread wear with the Michelins than they did with previous tires for the same amount of miles.

    To me it seemed that although the Michelins are more expensive, they will last longer and fewer problems so in the long run may be cheaper and are safer.

    I chose Michelin XPS Ribs.
  • So dry hitch weight is 2383, so load range E LT should be able to handle any load you put in it. The forest River Inc web site does not list GAWR.

    If you hop over to the TH section, I think you will find that you are on the right track! You will also fine similar tire threads with problem after problem with cheap OEM ST tires.

  • A 18k GVWR trailer may have 3500 lbs of hitch weight which leaves 14500 lb on the six tires. That equates to bit over 2400 lbs per tire as a minimum.

    The LT E at 3042 lb times six tires as Me says gives you a whoopin' 28 percent reserve capacity. IMO using the G614 at 3750 lb capacity is overkill and not the best idea for a trailer with 6k axles.

    I use LT E at 3042 lbs on a tri axle GN stock trailer with 6k axles. Ran the first set (Firestone Transforce HT) for 6 years and 48k miles with no tire issues with lots of off road use such as barn yards and pastures and gravel roads.

    6 XPS Ribs at 3042 each provide for 18252 lbs of capacity on the axles. What is the GAWR?

    The Bridgestone Duravis R250's or M895's are cheaper and as good as the Ribs.

    Do you have at least 33" center to center on the axles for LT235/85R16's, if not look at 245/75R16's. With three axles G614 might be an overkill, and they are VERY expensive.

    You are wise to dump the ST's!

    GVWR is 18000. Will check Center to Center measurement today. I do know that space between tires is tight so may have to look at the 245/75/16.

  • I have the GY 614s and have been extremely happy. However there is another alternative out there called Sailun Tires. Here Sailun Tires Several have been happy with those as well.
  • You might also look into the Geostar 574 14 ply, built similar to the Gy and about 1/3rd less price, we have about 7,000 miles on them and so far so good.....
