Tire decision... My turn :)

5th wheel is a Komfort 3530 40ft bunkhouse
GVWR is 15,500lbs.
Wheels are 16in and rated up to 110psi.

Making a few assumptions here since I honestly have not weighed the trailer but lets use the GVWR of 15,500 and the 20% pin weight "rule".

pin weight 3,100
wheel weight 3,100 x 4

I have pretty much narrowed my decision to Maxxis m8008 and the Goodyear g614.

Maxxis m8008 ST235/80R-16= 3,420 max load and $160.00 x 4
Goodyear g614 235/85R-16= 3,750 max load and $320.00 x 4

Assuming you owned my trailer and were not swimming in money which tire would you choose?

    ...........Most likely the Maxxis does NOT have a Steel matrix embedded in the sidewall , this is what prevents the weight of the trailer's side to side movement while traveling . The G614 , Michelin Ribs , and Sailun All Have a steel matric in their sidewalls . The steel matrix in both the tread and sidewall makes the listed tires above heavier than the ST grade of tires . , jf

    Some RV manufactures install Sailun S637 on new trailers. They are an all steel cord construction, just like the Goodyear G614. Goodyear will pay for any damage to your trailer if a tire blow's out and it is found to be defective. Sailun will not, but you are not paying for the insurance either. I already carry insurance that will cover the damage so I don't need Goodyear's.

    Neither I would get Sailuns.
    They seem to be every bit as good as the goodyear but much cheaper

    Check out 16" Sailun tire here

    I purchased 4 last year.

    IMO its a no brainer. The Maxxis isn't even in the same class as the all steel ply carcass G614 .
    However as Lantley says the Sailun S637 is a commercial grade LT235/85-16 G load range tire at 3750 lb capacity/110 psi would be my pick for a trailer with 7k axles.

    I have sent a email message into my closest tire dealer that handles Sailun. Ill see what he can do for me. In all honesty I have never heard of Sailun before coming to RV.NET not that that means anything. Thanks again for the additional option.

    I sure wouldn't put a Maxxis ST tire mor any ST brand on any 15500 lb trailer that size unless it was used little and not on long interstate runs at close to max loads.

    Looks like I would choose the Maxxis with a little trepidation, not sure how they get such a big price difference. Don't think I would drive over 65 with the Maxxis.
