Recommend tire for my use

[steelworker77]

Have a 2017 Nitro XLR toy hauler 5th wheel 17,200 gvw 2 7k axles. Had two tread separations happen within 5 miles of each other on way home today from trip. Has the 235/80/16 E rated Westlakes on it from factory.

Would like to order new tires tomorrow as well as start repairing damage.

Is there a certain size/brand/load rating I should be looking for? It seems the e rated tires are not heavy enough for my application. Any help appreciated

Were the separations on the same side of the trailer?

No both on front axle each side

That could be a load problem with the tires. On one side could be one tire going and overloading the other tire on that side.

To answer your question, Goodyear G614 or for around 25% less Sailun S637, anything else is china junk

Will the stock wheels handle the G614 @ 110 psi?

[A32Deuce]

Only restriction I have seen on wheels is load rating, no pressure limit. That's a steel wheel.

3 of the guys that we camp with are running the G614s at 100 psi, if you go much lower than that the tires are subject to -inner ply shear- when you turn corners, the rubber tries to tear away from the next layer of rubber.
The goodyears are $300/each, the Sailuns around 225/each

Back of my aluminum wheels say load limit is 3960lbs so I should be ok with the G614'S? I believe they are 3750 at 110 psi.

Your tire choice seems like a good plan to have extra capacity. Any more tire capacity would be wasted as exceeding the axle rating. Maxima tires are also a good choice, 808's?

On dual axle RV trailers one axle can be carrying much more weight than the other. You should get it all loaded-up again and find some scales to see what your individual axles are carrying. Sometimes even a single wheel position can be over weight.

I doubt your wheels are rated for LRG tires of any design. Ask the tire dealer. You should consider any of the steel cased ST235/80R16 LRG tires. By using that size the trailer's certification label stays valid and you can inflate the tires to any option above 80 PSI all the way to 110 PSI that will provide much needed load capacity reserves.

Steel valve stems are recommended and probably necessary for 110 PSI.

By the way; under the new load capacity reserve guidance from RVIA, the GY G614 would not qualify as OEM on certified 7000# axles.

Last fall I was driving in Iowa towing a 12,000 lb loaded 5th wheel. I had a catastrophic failure of the right 2 tires and a rim. I was driving 5 year old commercial Maxxis tires. I needed a new set of tires and found the Goodyear Endurance and a set of Carlisle tires at the same price with the CLS 16 ST235/80R16 with superior specs. With 14 ply rating, G load at 110 PSI and speed rating M (81MPH). The tire weighs 60 lbs and can support 4080 lbs. I have put about 8,000 miles on them and run about 67 MPH. Carlisle has a reputation for good trailer tires. These were made in China, but I feel many of the earlier problems with tires made there have been dealt with. Carlisle does make tires in the USA also.

That is not a fair comparison, the Endurance is not a 'G' rated tire; keep us informed how your chinese tires hold up
