Towmax PowerKing blow out pics

Yep this happened. Hard to believe the way the tread rolled off and sidewall split. Max air at 65psi was checked b4 leaving, about 20 miles into trip, going between 55-65 in 85 degree temps. Tires are 3 years old with just under 2k on them. These are Load D, Max GVW on trailer is 10600, upgrading to Load E now just to give the tires some capacity room.

  • I just posted on fifth wheel forum of my blow max failure on my 2014 Jayco Eagle. Load range E. Unbelievable that this just continues to happen.
  • Just replaced all 4 tires on my 2013 34" Jayco WhiteHawk. Same tire size and rating as yours. Tires a little over 3 years old with over 15,000 miles. Tires still had plenty of thread and basically looked new except for one that was wearing on the inside. Date code on the tires was 2/12 if I remember. Decided to upgrade since we're heading out on a 5,000 mile fall trip out west. Went with the new Carlisle HD, Load Range E. These tires are getting good reviews and are readily available at Discount Tire. I will post a review on them after we return. Good luck.
  • If they went minimal on the tires then the rims are probably rated for 65 psi like the tires. I think load range E tires require 80 psi.
  • Yes, Jayco got away with the D's because the truck carries some of the weight of the trailer...(the tongue weight).

    I'm one who is in favor of reserve tire payload...LRE's would be much better and give you that reserve.
  • This is a Travel Trailer. 36.2', dry: 945 tongue, 8500, 10600 GVW.

    Got it, makes perfect sense that the tongue weight would allow more room for the tires to meet weight. I am still going on caution to upgrade to Load E with the thinking of stiffer sidewalls and more room to allow the tires not to be so close to load. Taking the theory of towing with 80/20 capacity, probably wouldn't hurt to have the same mindset for the tires.
  • Is Jayco Eagle a 5er? Something over 2,000 lbs would be supported by the truck.

    If TT, then probably something in the range of 1,000 lbs supported by truck.

    Oops. Missed the last sentence. Yes, the weight on the truck reduces the amount of weight on the TT tires.
  • Interesting enough, the GVW is 10600, but these Load D Towmax that came on my Jayco Eagle show a max spec of 2560lb. So that comes to 360lbs under the rated GVW for the trailer. Am I right or missing/misunderstanding that these tires were placed under the GVW of the trailer and really should be upgraded by Jayco? Or does the tongue weight of 945lbs allow for lowering the tires to load D?
