I would sell them to someone with a work trailer on Craigslist at a price that no one could refuse.

I have a coworker that just had a blowout on one of his Blomax tires without warning. He said he cheked the tire pressure before leaving. He also said he had about 4000 miles on them. When I called the tire warenttee place they said I would need to take pictures,weight the trailer, and send it in before they would warranty the tires. Any trailer damage would be on me! Thus the 17.5 inch upgrade with 4805 pound capacity truck tires.

Geez, reading all these issues, I'm glad I opted for the Maxxis upgrade option on my TT when I ordered it! Anyone know when they started offering this as an option?

I was not aware that it was an option. When did that start? Many may be interested in it.

Not sure. I ordered my 2016, and it was an option. The trailer comes with 15" D wheels/tires, but I paid a bit under $500 to upgrade to 16" E Maxxis ST tires and wheels (including spare).

The 17.5s are almost bulletproof. I haul around a 30k pound excavator on 8 of them. Expensive upgrade but worth it if you dont want to worry about it. Unfortunately, They dont make any 17.5 wheels in a 6 lug pattern (that ive found).
Im getting ready to trash my 15" blowmaxs and upgrade to 16s and LT tires.

I wanted to make that change, and probably should have, but elected instead ($$) to keep the wheels and put on Maxis M8008 ST radials, E rated at 80psi for 3,420lbs. I too have the 6,000lb rated axles. I hoped that the extra 420lbs rated per tire over the axle would give me enough margin to at least keep the tires round and full of air.

So far (13,500 miles into a 15,000 mile trip) so good. The tires (which I check pressure on and inspect every day) look great.

HOWEVER, my next rig/upgrade will have 17.5" wheels and G114 H rated tires.
SSBN608, check for the GAWR on the side of the tailer. If it says 6000 pounds you are probably okay. My sticker said 7000 pounds but on the axles it said 6000.

I cruise at 62 miles per hour and always check for 80 psi before every trip. The tires have lots of tread left. When I got home I noticed the remaining 3 tire treads were bulged indicating tread seperation. I started to look at the trailer weight limits and discovered that the tires and wheels are not rated for hitch unloading (dynamic loads). Jayco calculates 20% of the weight to be on the truck. The problem is dips in the road cause dynamic loading far greater than the rated capacity. I also looked under the trailer for any damage and found that the Dexter axle sticker stated the capacity at 6000 pounds each. When I calculate 20% of the 12000 pounds and 1000 pounds of cargo weight being on the truck, the axles are overloaded by 626 pounds static. The Dexter axle site says that trailer manufacturers should account for dynamic loading. I contacted Dexter and asked if the warenttee would be honored under these conditions. They said if the axles are overloaded they would not be covered. I contacted Jayco and I am waiting for their them to call back. The cargo capacity stated on the factory sticker is 2600 pounds. With the axle capacity at 12000 pounds my true cargo capacity is only less than 400 pounds with a full load of fresh water. We dry camp and need to travel with water often.
Unless this trailer loads most of its cargo towards the front, a basic calc shows the axles to be overloaded at GVW by about 700 lbs, and, as you say, this is just static loading. This thing should have 7200 lb axles under it, IMO. I'd call your dealer and see if they can get Jayco to replace the axles, as you should be able to safely tow that thing at the 15,950 lb GVW spec'd for it. Also, the nickname for those tires is "BlowMaster". Either get a good set of LTs like Michelin XPS Ribs or Bridgestone Duravis R250s or jump up to the GY G614 or the equivalent Sailun tires, but you have to have 110 psi-rated wheels. The better option, so I've been told, is the 17.5" wheels and tires. Of course, having good tires does nothing for the overloaded axles. If your dealer can't, or won't, deal with Jayco, then call them directly and climb the "responsibility ladder". If you get stonewalled, then it's either attorney time, or you simply buy yourself a set of new axles and sell the old ones to offset the cost. Gives yourself an excuse to install as set of wet bolts and bronze bushings. :-/

Wheels are stamped with max psi rating. Either on the back side of the bead or, more rarely, in the valley inside, necessitating a tire break-down. Don't forget that, if you do jump up in wheel capacity, to make sure you get zero offset wheels or you'll lunch your bearings PDQ.

Since I need to upgrade the rims, I am going to 17.5 inch lynx rims with 215/75 R 17.5 Sailun tires. They are chinese but are load range H and have a 4800 pound capacity rather than 3520 that the Tomax has. They are also rated for 75 miles ler hour, Towmax 65. I ussually cruise around 62, the 75 mph rating should make them run cooler. I just found out today, Jayco installed the wrong axles. They installed 6000 pound capacity not 7000. They are going to replace the axles but I am on my own for tires and wheels. Before this fifthwheel I had a TT and went through eight Goodyear marathon tires due to tread separation. I switched to an off brand chinese tire and the tread separation problem went away. I would have paid for a Jayco tire and wheel upgrade if I knew you could get one.
Glad to see Jayco stepping up and acknowledging their mistake before it =really= cost them. Personally, I'd like to see the 7200 lb axles, but 7000 is a whole lot better! FWIW, I'm looking at an Eagle HT and saw they're offering a 16" Maxxis 8008 upgrade...on a 9950 lb GVW FW. Now =that's= overkill, IMO, but it's a start. :-)
